springboot整合web
在pom中添加web的整合jar依赖即可。
<!-- web依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
springboot整合FastJson
添加jar依赖
<!-- fastjson依赖 -->
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>fastjson</artifactId>
<version>1.2.15</version>
</dependency>
配置FastJson
方式一:让启动类继承WebMvcConfigurerAdapter
import java.util.List;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
@SpringBootApplication(scanBasePackages="com.yunxiang")
public class SpringApplications extends WebMvcConfigurerAdapter{
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
//创建FastJson的信息转换器
FastJsonHttpMessageConverter convert = new FastJsonHttpMessageConverter();
//创建FastJson的配置对象
FastJsonConfig config = new FastJsonConfig();
//将json数据进行格式化
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
//将配置添加到信息转换器中
convert.setFastJsonConfig(config);
//将FastJson的信息转换器添加到HttpMessageConverter中
converters.add(convert);
}
//springboot的入口
public static void main(String[] args) {
/*
* 第一个参数,springboot入口所在类的字节码
* 第二个参数,就是字符串数组的参数名
*/
SpringApplication.run(SpringApplications.class, args);
}
}
注:此过程会出现乱码,但是在springboot的全局配置文件中开启response即可。
spring.http.encoding.force=true
方式二:使用@Bean注入
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.web.HttpMessageConverters;
import org.springframework.context.annotation.Bean;
import org.springframework.http.converter.HttpMessageConverter;
import com.alibaba.fastjson.serializer.SerializerFeature;
import com.alibaba.fastjson.support.config.FastJsonConfig;
import com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter;
@SpringBootApplication(scanBasePackages="com.yunxiang")
public class SpringApplications {
@Bean
public HttpMessageConverters fastJsonMessageConverter(){
//创建FastJson的信息转换器
FastJsonHttpMessageConverter convert = new FastJsonHttpMessageConverter();
//创建FastJson的配置对象
FastJsonConfig config = new FastJsonConfig();
//将json数据进行格式化
config.setSerializerFeatures(SerializerFeature.PrettyFormat);
convert.setFastJsonConfig(config);
HttpMessageConverter<?> con = convert;
return new HttpMessageConverters(con);
}
public static void main(String[] args) {
/*
* 第一个参数,springboot入口所在类的字节码
* 第二个参数,就是字符串数组的参数名
*/
SpringApplication.run(SpringApplications.class, args);
}
}
springboot整合jsp
<!-- springboot整合jsp,需要是war工程,另外需要依赖另外两个包 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
<!-- maven项目为war类型时,要加这个插件后,可以不参加web.xml -->
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
springboot整合Freemarker
springboot官方不建议使用jsp,建议使用模板引擎(themleaf,velocity,freemarker等)。在默认的情况下Freemarker的文件以".ftl"结尾,文件存放在"src/main/resources"的"classpath"路径下的"templates"目录下。
<!-- Freemarker依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
Freemarker的默认配置信息,如果需要修改,就在springboot的全文配置文件中修改
#springboot整合freemarker的默认配置信息
spring.freemarker.allow-request-override=false
spring.freemarker.cache=true
spring.freemarker.check-template-location=true
spring.freemarker.charset=UTF-8
spring.freemarker.content-type=text/html
spring.freemarker.expose-request-attributes=false
spring.freemarker.expose-session-attributes=false
spring.freemarker.expose-spring-macro-helpers=false
spring.freemarker.suffix=.ftl
spring.freemarker.template-loader-path=classpath:/templates
spring.freemarker.settings.classic_compatible=true
Freemarker的模板
<html>
<head>
</head>
<body>
${name}
</body>
</html>
SpringBoot整合Thymeleaf
<!-- thymeleaf的依赖 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<!-- 解决thymeleaf使用非严格的html出现的异常 -->
<dependency>
<groupId>net.sourceforge.nekohtml</groupId>
<artifactId>nekohtml</artifactId>
<version>1.9.22</version>
</dependency>
springboot整合thymeleaf的配置信息(必须写在springboot的核心配置文件中)
#springboot整合thymeleaf
#关闭thymeleaf缓存 开发时使用 否则没有实时画面
spring.thymeleaf.cache=false
## 检查模板是否存在,然后再呈现
spring.thymeleaf.check-template-location=true
#Content-Type值
spring.thymeleaf.content-type=text/html
#启用MVC Thymeleaf视图分辨率
spring.thymeleaf.enabled=true
#应该从解决方案中排除的视图名称的逗号分隔列表
spring.thymeleaf.excluded-view-names=
#模板编码
spring.thymeleaf.mode=LEGACYHTML5
# 在构建URL时预先查看名称的前缀
spring.thymeleaf.prefix=classpath:/templates/
# 构建URL时附加查看名称的后缀.
spring.thymeleaf.suffix=.html
# 链中模板解析器的顺序
#spring.thymeleaf.template-resolver-order= o
# 可以解析的视图名称的逗号分隔列表
#spring.thymeleaf.view-names=
#thymeleaf end
thymeleaf模板
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1 th:text="${name}"></h1>
<a th:text="${name}"></a>
</body>
</html>
注:在thymeleaf模板中,使用"th:text=“
{}” "必须写在HTML的标签中,否则无法准确接收数据。
springboot整合QuartZ
springboot整合QuartZ时,需要在springboot的启动类上开启任务调度。
springboot的启动类
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication(scanBasePackages="com.yunxiang")
//开启任务调度
@EnableScheduling
public class SpringApplications {
public static void main(String[] args) {
SpringApplication.run(SpringApplications.class, args);
}
}
MyJob
import java.text.SimpleDateFormat;
import java.util.Date;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
//创建任务,并且将创建的任务存储在springboot中
@Component
public class MyJob {
//任务执行的时间间隔
//秒、分、时、日、月、年
//@Scheduled(cron = "0 0 0 0/1 * ?")
@Scheduled(fixedRate=1000)
public void run(){
System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()));
}
}
springboot整合JdbcTemplate
<!-- springboot整合jdbctemplate -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- mysql的依赖 -->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
数据库配置文件(配置在springboot的全局配置文件中)
#配置数据库
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf-8
