SpringBoot中默认是不支持jsp的，但是我们某些情况下可以又需要用到，所以本文记录下SpringBoot整合jsp的过程

整合JSP页面

1.创建控制器

  创建一个自定义的控制器，处理请求，并跳转到jsp页面

/**
 * @program: springboot-02-jsp
 * @description: SpringBoot整合jsp
 * @author: 波波烤鸭
 * @create: 2019-05-12 21:19
 */
@Controller
public class UserController {

    /**
     *
     * @param model
     * @return
     */
    @RequestMapping("/show")
    public String query(Model model){
       model.addAttribute("list",Arrays.asList("张三","李四","王五"));
        return "user";
    }
}

2.配置视图解析器前后缀

  在application.properties中配置

# 配置视图解析器的前后缀
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

3.创建jsp文件

  在项目的main目录下创建webapp/jsp目录

  项目设置web模块，默认没有创建jsp页面的功能，我们需要添加设置

按照如下设置

pom文件修改

<?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"

创建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"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<!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>
    <h1>JSP页面</h1>
    <c:forEach items="${list }" var="d">
       ${d}<br>
    </c:forEach>

</body>
</html>

5.启动测试

  启动方式注意，与之前有区别，如图:

访问请求: http://localhost:8080/show

搞定~ 整合成功
