最近一直在练习SpringBoot，但是呢，由于习惯使用了SpringMVC+jsp开发项目，所以页面希望用jsp来实现，但是springBoot默认不支持jsp，而是使用自己家族里面的模板技术，所以如果我们需要使用jsp，那需要利用springBoot整合jsp，接下来就简单的整合下JSP，虽然官方并不推荐...... 本实例Github地址10-jsp

项目一览

注意：其中webapp为自己建的目录，包括WEB-INF、jsp、hello.jsp、web.xml都是自己建的

web.xml

hello.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html lang="zh">
<head>
    <title>Hello jsp</title>
</head>
<body>
    <h1>Hello Jsp</h1>
</body>
</html>

application.properties配置文件

这个应该就很熟悉了

#页面默认前缀目录
spring.mvc.view.prefix=/WEB-INF/jsp/
#页面默认后缀目录
spring.mvc.view.suffix=.jsp

JspController

JspController.class

package com.perfree.jsp.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * 测试jsp Controller控制层
 */
@Controller
public class JspController {

    @RequestMapping("/hello")
    public String hello(){
        return "hello";
    }
}

到这里呢，基本就算是完成了，下边要特别注意运行方式，否则会一直404，看到很多小伙伴都是错在这里.......
