springboot内部对jsp的支持并不是特别理想，而springboot推荐的视图是Thymeleaf，对于java开发人员来说还是大多数人员喜欢使用jsp
1、创建maven项目，添加pom依赖
<!--springboot项目依赖的父项目-->
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.RELEASE</version>
</parent>
<dependencies>
<!--注入springboot启动器-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- jstl标签库 -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
</dependency>
<!-- jasper，tomcat对jsp的监听 -->
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
</dependencies>
2、创建springboot的全局配置文件application.porerties
#视图层位置前缀 spring.mvc.view.prefix=/WEB-INF/jsp/ #视图层后缀 spring.mvc.view.suffix=.jsp
3、创建controller
package com.bjsxt.controller;
import com.bjsxt.pojo.User;
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;
/**
* Created by Administrator on 2019/2/6.
*/
@Controller
public class UserController {
@RequestMapping("/toUserList")
public String toUserList(Model model){
List<User> userList=new ArrayList<User>();
userList.add(new User(1L,"张三","男"));
userList.add(new User(2L,"李四","女"));
userList.add(new User(3L,"王五","男"));
model.addAttribute("userList",userList);
return "user_list";
}
}
4、创建jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <head> <title>用户列表</title> </head> <body> <table border="1px solid red"> <tr> <th>id</th> <th>姓名</th> <th>性别</th> </tr> <c:forEach items="${userList}" var="user"> <tr> <td>${user.id}</td> <td>${user.name}</td> <td>${user.sex}</td> </tr> </c:forEach> </table> </body> </html>
5、创建启动类
package com.bjsxt;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* Created by Administrator on 2019/2/6.
*/
@SpringBootApplication
public class App {
public static void main(String[] args){
SpringApplication.run(App.class,args);
}
}
项目目录结构
