文章标签 SpringBoot项目 SpringBoot+Mybatis spring ci 文章分类 架构后端开发

一、项目简述

1. 开发工具：IDEA

2. 框架：SpringBoot + tk.Mybatis + Maven ，并集成JSP页面。

3. 本项目只是一个简单的demo，里面进行了基础的视图解析测试、JSON数据测试、数据库连接测试、log日志打印以及TK.Mybatis插件自动生成PO类、Mapper接口和对应的xml文件。

二、项目搭建

第一部分：创建项目

1. File-->New-->Project..-->Spring Initializr-->Next-->Next

2. 此时处于依赖选择这一步，本项目所选择的依赖如下：

Core：Lombok(把属性字段的set和get方法注解化)

Web：Web

SQL：MySQL、Mybatis

3. 选择完依赖后，点击Next-->Finish。此时一个SpringBoot框架的雏形就出来了。

4. 此时搭建的SpringBoot框架，是没有webapp这个模块的，需要手动添加配置，具体步骤在文章的第四部分有叙述。

第二部分：完善项目配置

1. 完善pom.xml文件【此处把本项目中所用的依赖提前粘出来】

2. application.properties配置

#数据库配置
spring.datasource.url=jdbc:mysql://192.168.80.186:3306/bissv100
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.max-idle=10
spring.datasource.max-wait=10000
spring.datasource.min-idle=5
spring.datasource.initial-size=5

# mybatis配置
mybatis.typeAliasesPackage=com.iyungu.phantaci.po
mybatis.mapperLocations=classpath:com/iyungu/phantaci/mapper/*.xml


#demo-two项目名
server.servlet.context-path=/demo-two
#服务IP
server.port=8080

#视图解析器
spring.mvc.view.prefix = /WEB-INF/jsp/
spring.mvc.view.suffix = .jsp

3. generatorConfig.xml【tk.mybatis插件自动生成】

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
    <properties resource="application.properties"/>

    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value="`"/>
        <property name="endingDelimiter" value="`"/>
        <property name="autoDelimitKeywords" value="true"/>

        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.iyungu.phantaci.util.MyMapper"/>
        </plugin>

        <jdbcConnection driverClass="${spring.datasource.driver-class-name}" connectionURL="${spring.datasource.url}" userId="${spring.datasource.username}" password="${spring.datasource.password}">
        </jdbcConnection>

        <!--PO类所在位置-->
        <javaModelGenerator targetPackage="com.iyungu.phantaci.po" targetProject="src/main/java"/>
        <!--xml文件所在位置-->
        <sqlMapGenerator targetPackage="com.iyungu.phantaci.mapper" targetProject="src/main/java"/>
        <!--Dao接口所在位置-->
        <javaClientGenerator targetPackage="com.iyungu.phantaci.dao" targetProject="src/main/java" type="XMLMAPPER"/>

        <table schema="DEMO-TWO-TEST" tableName="u_user">
            <!--mysql 配置-->
            <generatedKey column="id" sqlStatement="Mysql" identity="true"/>
            <!--oracle 配置-->
            <!--<generatedKey column="id" sqlStatement="select SEQ_{1}.nextval from dual" identity="false" type="pre"/>-->
        </table>
    </context>
</generatorConfiguration>

使用方法：打开Maven Projects-->点击自己的项目-->Plugins-->点击mybatis-generator-->即可生成PO，Mapper接口及对应的XML。

第三部分：部分代码

1. Controller层

package com.iyungu.phantaci.controller;

import com.iyungu.phantaci.enums.ExceptionCode;
import com.iyungu.phantaci.po.UUser;
import com.iyungu.phantaci.service.HelloService;
import com.iyungu.phantaci.vo.Message;
import com.iyungu.phantaci.vo.ResponseUtil;
import com.iyungu.phantaci.vo.test.People;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * @Author: Wang Yarui
 * @Description:
 * @Date: Created in 10:40 2018/6/27
 * @Modified By:
 */
@Controller
@RequestMapping("/ph")
public class Hello {

    private static final Logger logger = Logger.getLogger(Hello.class);

    @Autowired
    private HelloService helloService;

    /**

     * @Date: Created in 10:43 2018/6/27
     * @Param:
     * @Return:
     */
    @GetMapping(value = "/showHello")
    public String showHello(String name) {
        if (name == null) {
            return "test/hello";
        }
        return "test/succ";
    }

    /**

     */
    @GetMapping(value = "/testJson")
    @ResponseBody
    public Message testJson() {
        People people = new People();
        return ResponseUtil.responseBody(people);
    }

    /**

     * @Date: Created in 9:39 2018/7/2

     */
    @GetMapping(value = "/getUserInfoById")
    @ResponseBody
    public Message getUserInfoById(Long userId) {

        logger.debug(String.format("getUserInfoById()方法开始执行，参数userId:{%s}",userId));
        if (userId == null) {
            return ResponseUtil.reponseBody(ExceptionCode.REQUEST_PARAM_ERROR.getCode(),ExceptionCode.REQUEST_PARAM_ERROR.getMsg());
        }

        UUser user = helloService.getUserInfoById(userId);
        logger.debug("getUserInfoById()方法结束执行");
        return ResponseUtil.responseBody(user);
    }

    /**
     * @Author: wangyarui@iyungu.com

    @GetMapping("/testLoggerInfo")
    @ResponseBody
    public Message getLoggerInfo(int num) {

        logger.debug(String.format("getLoggerInfo()方法开始执行，参数num:{%s}",num));
        int result = 0;
        try {
            result = 5/num;
        } catch (Exception e) {
            logger.error("分母不能为0",e);
            e.printStackTrace();
        }
        logger.debug("getLoggerInfo()方法结束执行");
        return ResponseUtil.responseBody(result);
    }

    /**
     * @Author: wangyarui@iyungu.com

     * @Date: Created in 11:22 2018/7/3
     * @Param: [userId]
     * @Return: com.iyungu.phantaci.vo.Message
     */
    @GetMapping("/testLoggerSql")
    @ResponseBody
    public Message getUserName(Long userId) {

        logger.debug(String.format("getUserName()开始执行,参数userId:{%s}",userId));
        if (userId == null) {
            logger.debug("无参数，getUserName()结束执行");
            return ResponseUtil.reponseBody(ExceptionCode.REQUEST_PARAM_ERROR.getCode(),ExceptionCode.REQUEST_PARAM_ERROR.getCode());
        }
        String userName = helloService.getUserNameById(userId);
        logger.debug("getUserName()结束执行");
        return ResponseUtil.responseBody(userName);
    }

}

2. config文件--->MybatisConfig

package com.iyungu.phantaci.config;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.context.annotation.Bean;


public class MyBatisConfig {

    @Bean(name = "sqlSessionFactory")
    public SqlSessionFactory sqlSessionFactoryBean() {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        try {
            return bean.getObject();
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException(e);
        }
    }
}

config文件--->MybatisMapperScannerConfig

package com.iyungu.phantaci.config;

import org.springframework.boot.autoconfigure.AutoConfigureAfter;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import tk.mybatis.spring.mapper.MapperScannerConfigurer;

import java.util.Properties;


@Configuration
//必须在MyBatisConfig注册后再加载MapperScannerConfigurer，否则会报错
@AutoConfigureAfter(MyBatisConfig.class)
public class MyBatisMapperScannerConfig {
    @Bean
    public MapperScannerConfigurer mapperScannerConfigurer() {
        MapperScannerConfigurer mapperScannerConfigurer = new MapperScannerConfigurer();
        mapperScannerConfigurer.setSqlSessionFactoryBeanName("sqlSessionFactory");
        mapperScannerConfigurer.setBasePackage("com.iyungu.phantaci.dao");

        //初始化扫描器的相关配置，这里我们要创建一个Mapper的父类
        Properties properties = new Properties();
        properties.setProperty("mappers", "com.iyungu.phantaci.util.MyMapper");
        properties.setProperty("notEmpty", "false");
        properties.setProperty("IDENTITY", "MYSQL");

        mapperScannerConfigurer.setProperties(properties);

        return mapperScannerConfigurer;
    }
}

3. 注意：util文件--->MyMapper

package com.iyungu.phantaci.util;

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;


public interface MyMapper<T> extends Mapper<T>, MySqlMapper<T> {
    //TODO
    //FIXME 特别注意，该接口不能被扫描到，否则会出错
}

第四部分：补充

1. 缺少webapp模块

2.完整项目下载

3.项目目录
