2.创建ReportConfig

package com.cn.report ;

import com.bstek.ureport.definition.datasource.BuildinDatasource;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.web.servlet.ServletRegistrationBean;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;
import org.springframework.stereotype.Component;

import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.SQLException;

@Configuration
@ImportResource("classpath:ureport-console-context.xml")
public class ReportConfig {

    /**
     * 进行注册Servlet
     * 配置 UReport2 需要使用到的servlet
     */

    @Bean
    public ServletRegistrationBean buildUReportServlet() {

        /**
         * @param  servlet
         * @param  urlMappings 值为“/ureport/*”的 urlMappings 是一定不能变的，否则系统将无法运行。
         */
        return new ServletRegistrationBean(new MyReportServlet(), "/ureport/*");
    }

    @Component
    @Slf4j
    public static class MyDataSource implements BuildinDatasource {

        @Autowired
        private DataSource dataSource;

        @Override
        public String name() {

        }

        @Override

            } catch (SQLException e) {
                log.error(e.getMessage() + "-" + e.getSQLState());
            }
            return null;
        }
    }
}

3.创建MyReportServlet

package com.cn.report ;

import com.bstek.ureport.console.RequestHolder;
import com.bstek.ureport.console.ServletAction;
import com.bstek.ureport.console.UReportServlet;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.context.WebApplicationContext;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Collection;
import java.util.HashMap;
import java.util.Map;


@Slf4j
public class MyReportServlet extends UReportServlet {

    private static final long serialVersionUID = 633049461276487971L;
    private Map<String, ServletAction> actionMap = new HashMap<>();

    @Override
    public void init(ServletConfig config) throws ServletException {
        super.init(config);
        WebApplicationContext applicationContext = getWebApplicationContext(config);
        Collection<ServletAction> handlers = applicationContext.getBeansOfType(ServletAction.class).values();
        for (ServletAction handler : handlers) {
            String url = handler.url();
            if (actionMap.containsKey(url)) {
                throw new RuntimeException("Handler [" + url + "] already exist.");
            }
            actionMap.put(url, handler);
        }
    }

    private void outContent(HttpServletResponse resp, String msg) throws IOException {
        resp.setContentType("text/html");
        PrintWriter pw = resp.getWriter();
        pw.write("<html>");
        pw.write("<header><title>UReport Console</title></header>");
        pw.write("<body>");
        pw.write(msg);
        pw.write("</body>");
        pw.write("</html>");
        pw.flush();
        pw.close();
    }

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        String path = req.getContextPath() + URL;
        String uri = req.getRequestURI();
        String targetUrl = uri.substring(path.length());
        if (targetUrl.length() < 1) {
            outContent(resp, "Welcome to use ureport,please specify target url.");
        } else {
            int slashPos = targetUrl.indexOf("/", 1);
            if (slashPos > -1) {
                targetUrl = targetUrl.substring(0, slashPos);
            }
            ServletAction targetHandler = actionMap.get(targetUrl);
            if (targetHandler == null) {
                this.outContent(resp, "Handler [" + targetUrl + "] not exist.");
            } else {
                RequestHolder.setRequest(req);

                try {
                    targetHandler.execute(req, resp);
                } catch (Exception ex) {
                    log.error("error---> {}", ex.getMessage());
                    throw new ServletException(ex);
                } finally {
                    RequestHolder.clean();
                }

            }
        }
    }
}

可视化界面初步配置完成

此时访问网址：http://localhost:9020/ureport/designer可以看到ureport。但是此时只能保存报表到session中不能持久化保存。

持久化到服务器中

创建在report中创建reportFile包，

1.resources中创建config.properties

#配置文件系统对应的报表文件地址
ureport.fileStoreDir=./src/main/java/com/cn/report/reportFile/
# 是否禁用
ureport.disableFileProvider=false
ureport.debug=true
ureport.disableHttpSessionReportCache=false
# 配置ureport根路径
ureport.contextPath=/ureport

2.resources中创建context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <!-- 创建context.xml是第六步，引入ureport2报表xml配置文件 -->
    <import resource="classpath:ureport-console-context.xml" />
    <bean id="propertyConfigurer" parent="ureport.props">
        <property name="location">
            <value>classpath:config.properties</value>
        </property>
    </bean>
</beans>

3.在report包中创建UreportConfig类

package com.cn.report;

import com.bstek.ureport.console.UReportServlet;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

/**
 * UreportConfig
 *
 * @author wangyq
 * @create 2023/10/11
 */


@ImportResource("classpath:context.xml")
@EnableAutoConfiguration
@Configuration
@ComponentScan(basePackages = "com.cn")

public class UreportConfig {

    @Bean
    public ServletRegistrationBean buildUreportServlet() {
        return new ServletRegistrationBean(new UReportServlet(), "/ureport/*");

    }
}

此时访问http://localhost:9020/ureport/designer保存报表即可存到本地

持久化到数据库中

1.创建数据库表结构

CREATE TABLE `t_report_tpl` (
  `ID` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NOT NULL DEFAULT '',
  `NAME` varchar(255) DEFAULT NULL,
  `CONTENT` text,
  `CREATE_DATE` datetime DEFAULT NULL,
  `LAST_UPDATE` datetime DEFAULT NULL,
  `display` varchar(100) DEFAULT NULL,
  `status` char(1) DEFAULT NULL,
  PRIMARY KEY (`ID`) USING BTREE,
  KEY `name_index` (`NAME`) USING BTREE
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci ROW_FORMAT=DYNAMIC;

2.创建实体类ReportTpl

package com.cn.pojo;

import com.bstek.ureport.provider.report.ReportFile;
import com.cn.report.RptUpdateSerializer;

import org.apache.ibatis.annotations.AutomapConstructor;
import org.codehaus.jackson.map.annotate.JsonSerialize;

    }

    public void setDisplay(String display) {
        this.display = display;
    }

    public Date  getCreate_date() {
        return create_date;
    }

    public void setCreate_date(Date create_date) {
        this.create_date = create_date;
    }

    public Date getLast_update() {
        return last_update;
    }

    public void setLast_update(Date last_update) {
        this.last_update = last_update;
    }

    /**
     * 自定义日期类，携带报表模板信息，在序列化时展示报表模板的说明
     */
    public static class MyDate extends Date{
        Date val;

        ReportTpl reportTpl;

        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");


        public MyDate(Date val) {
            this.val = val;
        }

        public Date getVal() {
            return val;
        }

        public void setVal(Date val) {
            this.val = val;
        }

        public ReportTpl getReportTpl() {
            return reportTpl;
        }

        public void setReportTpl(ReportTpl reportTpl) {
            this.reportTpl = reportTpl;
        }

        public SimpleDateFormat getDateFormat() {
            return dateFormat;
        }

        public void setDateFormat(SimpleDateFormat dateFormat) {
            this.dateFormat = dateFormat;
        }

        /**
         * 覆盖toString方法，此方法将在自定义的序列化工具类中调用
         * @see
         * @return
         */
        @Override
        public String toString() {
            return "<span title='"+ getDateFormat().format(val)+ "' >" + getReportTpl().getDisplay()  +"</span>";
        }
    }
}

3.创建ReportApi接口

package com.cn.service;

import com.bstek.ureport.export.html.HtmlReport;
import com.cn.pojo.ReportTpl;


import java.util.List;
import java.util.Map;

/**
 * ureport2报表相关的接口
 *
 */
public interface ReportApi {

    /**
     * 返回报表结构
     *
     * @param templateFileName 报表文件名 tpl:templateFileName.xml
     * @param params           参数
     * @return
     */
    HtmlReport getHTML(String templateFileName, Map<String, Object> params);


    /**
     * 返回报表结构
     *
     * @param templateFileName 报表文件名 tpl:templateFileName.xml
     * @param params           参数
     * @param pageNum          页码
     * @return
     */
    HtmlReport getHTMLPage(String templateFileName, Map<String, Object> params, int pageNum);

    /**
     * 插入报表模板
     *
     * @param reportTpl
     * @return
     */
    int insertTpl(ReportTpl reportTpl);


    /**
     * 模板列表
     *
     * @return
     */
    List<ReportTpl> listTpl();

    /**
     * 查找
     *
     * @param tplName
     * @return
     */
    ReportTpl findTplByName(String tplName);

    /**
     * 更新报表模板
     *
     * @param reportTpl
     * @return
     */
    int update(ReportTpl reportTpl);

    /**
     * 删除报表模板
     *
     * @param tplName
     * @return
     */
    int delete(String tplName);


}

4.创建ReportApiImpl实现类

package com.cn.service.impl;




import com.bstek.ureport.export.ExportManager;
import com.bstek.ureport.export.html.HtmlReport;

import com.cn.mapper.ReportTplMapper;
import com.cn.pojo.ReportTpl;
import com.cn.service.ReportApi;
import com.github.pagehelper.Page;
import lombok.extern.slf4j.Slf4j;

import org.codehaus.jackson.map.ObjectMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import javax.annotation.Resource;
import java.text.SimpleDateFormat;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.time.temporal.ChronoUnit;
import java.time.temporal.TemporalAdjusters;
import java.util.*;
import java.util.regex.Pattern;



@Slf4j
@Service
public class ReportApiImpl implements ReportApi {


    @Resource
    private ReportTplMapper reportTplMapper;
    @Resource
    private ExportManager exportManager;

    public static final String RPT_NEED_PAGE = "1";
    public static final String RPT_NOT_NEED_PAGE = "0";
    /**
     * 返回报表结构
     *
     * @param templateFileName 报表文件名 file:templateFileName.xml
     * @param params           参数
     * @return
     */
    @Override
    public HtmlReport getHTML(String templateFileName, Map<String, Object> params) {

        //是否需要分页
        String needPage = params.getOrDefault("needPage", RPT_NOT_NEED_PAGE).toString();
        if (needPage.equals(RPT_NEED_PAGE)) {
            HtmlReport report = exportManager.exportHtml(templateFileName, "", params);
            Page currentPage = (Page) params.get("currentPage");
            report.setTotalPage(currentPage.getPages());
            report.setPageIndex(currentPage.getPageNum());
            report.setColumn((int) currentPage.getTotal());

            log.debug("pages---->{}, pageNum={}, total={}, time -->{}", currentPage.getPages(), currentPage.getPageNum(), currentPage.getTotal(), System.currentTimeMillis());

            return report;
        } else {
            return exportManager.exportHtml(templateFileName, "", params);
        }
    }


    /**
     * 返回报表结构
     *
     * @param templateFileName 报表文件名 file:templateFileName.xml
     * @param params           参数
     * @param pageNum          页码
     * @return
     */
    @Override
    public HtmlReport getHTMLPage(String templateFileName, Map<String, Object> params, int pageNum) {
        return exportManager.exportHtml(templateFileName, "", params, pageNum);
    }

    /**
     * 插入报表模板
     *
     * @param reportTpl
     * @return
     */
    @Override
    public int insertTpl(ReportTpl reportTpl) {
        return reportTplMapper.insert(reportTpl);
    }


    /**
     * 模板列表
     *
     * @return
     */
    @Override
    public List<ReportTpl> listTpl() {
        return reportTplMapper.list();
    }

    /**
     * 查找
     *
     * @param tplName
     * @return
     */
    @Override
    public ReportTpl findTplByName(String tplName) {
        return reportTplMapper.findByName(tplName);
    }


    /**
     * 更新报表模板
     *
     * @param reportTpl
     * @return
     */
    @Override
    public int update(ReportTpl reportTpl) {
        return reportTplMapper.update(reportTpl);
    }

    /**
     * 删除报表模板
     *
     * @param tplName
     * @return
     */
    @Override
    public int delete(String tplName) {
        return reportTplMapper.delete(tplName);
    }


}

5.创建ReportTplMapper数据查询接口

package com.cn.mapper;

import com.cn.pojo.ReportTpl;

import org.apache.ibatis.annotations.*;

import java.util.List;


@Mapper
public interface ReportTplMapper {

    @Insert("INSERT INTO T_REPORT_TPL(id, name, display, content, status, create_date, last_update) VALUES(#{id, jdbcType=VARCHAR}, #{name, jdbcType=VARCHAR}, #{display, jdbcType=VARCHAR}, #{content, jdbcType=VARCHAR}, #{status, jdbcType=INTEGER},  NOW(), NOW())")
    int insert(ReportTpl reportTpl);


    @Delete("UPDATE T_REPORT_TPL SET status='0' WHERE name=#{name} ")
    int delete(Object name);


    @Update("<script>UPDATE T_REPORT_TPL  SET   last_update = NOW() " +
            "<if test=\"name != '' and name != null\">, name=#{name}</if>\n" +
            "<if test=\"display != '' and display != null\">, display=#{display}</if>\n" +
            "<if test=\"content != '' and content != null\">, content=#{content}</if>\n" +
            " WHERE id =#{id}</script>")
    int update(ReportTpl reportTpl);


    @Select("SELECT id,name, display,content,create_date,last_update FROM T_REPORT_TPL WHERE ID=#{id}")
    ReportTpl get(Object id);

    @Select("SELECT  id,name, display,content,create_date,last_update FROM T_REPORT_TPL WHERE NAME=#{name} AND status='1'")
    ReportTpl findByName(String name);

    @Select("SELECT id,name,display,content,create_date,last_update FROM T_REPORT_TPL WHERE status='1' ORDER BY name,last_update")
    List<ReportTpl> list();
}

6.report包中创建ReportFileProvider

package com.cn.report ;

import com.bstek.ureport.provider.report.ReportFile;
import com.bstek.ureport.provider.report.ReportProvider;

import com.cn.pojo.ReportTpl;
import com.cn.service.ReportApi;
import lombok.extern.slf4j.Slf4j;

import org.apache.commons.io.IOUtils;
import org.springframework.stereotype.Component;

import javax.annotation.Resource;


import java.io.InputStream;
import java.io.Serializable;
import java.nio.charset.Charset;
import java.util.Date;
import java.util.List;
import java.util.Map;
import java.util.UUID;
import java.util.stream.Collectors;


@Component
@Slf4j
public class ReportFileProvider implements ReportProvider, Serializable {

    private static final String prefix = "tpl:";

    @Resource
    private ReportApi statisticsApi;

    private String getFileName(String file){
        return file.substring(prefix.length());
    }




    @Override
    public InputStream loadReport(String file) {
        String fileName = getFileName(file);
        Map<String, String> nameInfo = ReportTpl.parseName(fileName);
        ReportTpl reportTpl = statisticsApi.findTplByName(nameInfo.get("name"));
        if(reportTpl == null){
            log.error("未找到报表{}", fileName);
            throw new RuntimeException("未找到报表模板！");
        }else {
            return IOUtils.toInputStream(reportTpl.getContent(), Charset.forName("UTF-8"));
        }
    }

    @Override
    public void deleteReport(String fileName) {
        Map<String, String> nameInfo = ReportTpl.parseName(getFileName(fileName));
        statisticsApi.delete(nameInfo.get("name"));
    }

    @Override
    public List<ReportFile> getReportFiles() {
        return statisticsApi.listTpl().stream().collect(Collectors.toList());
    }

    @Override
    public void saveReport(String file, String content) {
        String fileName = getFileName(file);
        Map<String, String> nameInfo = ReportTpl.parseName(fileName);
        ReportTpl reportTpl = statisticsApi.findTplByName(nameInfo.get("name"));
        if(reportTpl != null){
            reportTpl.setContent(content);
            reportTpl.setDisplay(nameInfo.get("display"));
            reportTpl.setLast_update(new Date());
            statisticsApi.update(reportTpl);
        } else {
            reportTpl = new ReportTpl("", new Date());
            reportTpl.setId(UUID.randomUUID().toString());
            reportTpl.setContent(content);
            reportTpl.setName(nameInfo.get("name"));
            reportTpl.setDisplay(nameInfo.get("display"));
            reportTpl.setStatus(ReportTpl.S_NORMAL);
            statisticsApi.insertTpl(reportTpl);
        }
    }

    @Override
    public String getName() {
        return "报表模板储存";
    }

    @Override
    public boolean disabled() {
        return false;
    }

    @Override
    public String getPrefix() {
        return this.prefix;
    }
}

7.report包创建RptUpdateSerializer

package com.cn.report ;

import org.codehaus.jackson.JsonGenerator;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.JsonSerializer;
import org.codehaus.jackson.map.SerializerProvider;

import java.io.IOException;
import java.util.Date;

/**
 * 日期序列化，用于ureport列示报表时，展示报表说明
 */
public final class RptUpdateSerializer extends JsonSerializer<Date> {
    /**
     * Method that can be called to ask implementation to serialize
     * values of type this serializer handles.
     *
     * @param value    Value to serialize; can <b>not</b> be null.
     * @param jgen     Generator used to output resulting Json content
     * @param provider Provider that can be used to get serializers for
     */
    @Override
    public void serialize(Date value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonProcessingException {
        jgen.writeString(value.toString());
    }
}

创建报表查询

1.创建testController（参数须遵守该规则）

(String dsName, String datasetName, Map<String, Object> parameters)

package com.cn.controller;

import com.bstek.ureport.export.html.HtmlReport;
import com.cn.pojo.testPojo;
import com.cn.service.ReportApi;
import com.cn.service.testService;
import com.cn.util.Result;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.List;
import java.util.Map;

/**
 * testController
 *
 * @author wangyq
 * @create 2023/10/11
 */

@RestController
public class testController {
    @Autowired
    private testService testService;
    @Autowired
    private ReportApi reportApi;
    @GetMapping("/get")
    private String get(){
        return "test";
    }

    @GetMapping("/getuReport")
    public List<testPojo> ureportList(String dsName, String datasetName, Map<String, Object> parameters){
        return  testService.ureportList();
    }


//前端访问该接口获取数据
    @GetMapping("/show")
    public Result show(@RequestParam Map<String, Object> params) {
        String fileName = params.get("templateFileName").toString();
        return Result.success(reportApi.getHTML(fileName, params));
    }
}

配置成功

此时访问网址：http://localhost:9020/ureport/designer可以保存报表到数据库中,通过springbean连接，根据类名创建，然后选择方法名。
