新建项目
给pom文件添加这两个依赖
pom.xml文件
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.6.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com</groupId> <artifactId>gongspingjsp</artifactId> <version>0.0.1-SNAPSHOT</version> <name>gongspingjsp</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- jstl --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> </dependency> <!-- jasper --> <dependency> <groupId>org.apache.tomcat.embed</groupId> <artifactId>tomcat-embed-jasper</artifactId> <scope>provided</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project>
创建 springBoot 的全局配置文件， application.properties 
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
新建controller包
在这个包下新建UserController类
package com.gongspingjsp.controller; import com.gongspingjsp.pojo.Users; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import java.util.ArrayList; import java.util.List; /** * SpringBoot 整合 jsp * * */ @Controller public class UserController { /** * 处理请求， 产生数据 */ @RequestMapping("/showUser") public String showUser(Model model){ List<Users> list = new ArrayList<>(); list.add(new Users(1,"张三",20)); list.add(new Users(2,"李四",22)); list.add(new Users(3,"王五",24)); //需要一个 Model 对象 model.addAttribute("list",list); //跳转视图 return "userList"; } }
新建pojo包和User类
package com.gongspingjsp.pojo; public class Users { private Integer userid; private String username; private Integer userage; public Integer getUserid() { return userid; } public void setUserid(Integer userid) { this.userid = userid; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public Integer getUserage() { return userage; } public void setUserage(Integer userage) { this.userage = userage; } public Users(Integer userid, String username, Integer userage) { super(); this.userid = userid; this.username = username; this.userage = userage; } public Users() { super(); // TODO Auto-generated constructor stub } }
新建以下目录
创建userList.jsp文件
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<table border="1" align="center" width="50%">
<tr>
<th>ID</th>
<th>Name</th>
<th>Age</th>
</tr>
<c:forEach items="${list }" var="user">
<tr>
<td>${user.userid }</td>
<td>${user.username }</td>
<td>${user.userage }</td>
</tr>
</c:forEach>
</table>
</body>
</html>
创建启动类App.java
package com.gongspingjsp; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; /** * SpringBoot 启动类 * * * */ @SpringBootApplication public class App { public static void main(String[] args){ SpringApplication.run(App.class,args); } }
运行启动类
