　　1.2 在springboot项目的main目录下创建webapp/WEB-INF/jsp的文件夹目录

　　　　技巧01：这里创建的是文件夹而不是包

　　　　技巧02：在jsp文件夹里面创建JSP文件

　　　　

　　1.3 在配置文件中配置JSP文件的位置

　　　　

　　　　技巧01：需要从/WEB-INF开始，不要从/webapp开始，否则会提示找不到的(因为WEB项目会从WEB-INF下面寻找JSP文件)，错误信息如下

　　　　　　

　　1.4 创建一个jsp文件　　　

<%@page contentType="text/html;charset=utf-8" %>
<html>

<head>
    <title>主页面</title>
</head>

<body>
    <h2>Welcomo to the city of ChongQing.</h2>
</body>

</html>

　　1.5 创建控制层类

package cn.xiangxu.springboottest.controller;

import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@Slf4j
public class JspController {

    @GetMapping(value = "/index")
    public String toIndex() {
        log.info("正在进入登录页面.......");
        return "index";
    }
}

　　技巧01：不能使用@RestController代替@Controller，因为@RestController默认的返回值是json格式，就不会根据字符串去寻找相应的JSP文件了
