1.新建springboot项目,选择以war包的方式package;

2.勾选Web模块,DevTools可不选(用作热部署,不影响运行)

3.创建完成后,项目结构如下图:

4.pom.xml文件中添加jsp的依赖

        <dependency>

            <groupId>org.apache.tomcat.embed</groupId>

            <artifactId>tomcat-embed-jasper</artifactId>

            <scope>provided</scope>

        </dependency>

        <dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>jstl</artifactId>

        </dependency>

5.在application.properties文件中添加以下内容:

#路径,在webapp文件夹下新建文件夹WEB-INF,在往下建文件夹jsp

spring.mvc.view.prefix=/WEB-INF/jsp/

#文件名的后缀,例如:index.jsp,放在jsp文件夹下

spring.mvc.view.suffix=.jsp

.yml 文件配置如下:

spring:
    mvc:
        view:
            prefix: /WEB-INF/test/
            suffix: .jsp

6.新建index.jsp文件,路径结构如图:

7.index.jsp页面内容如下:

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

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

<!DOCTYPE html>

<html>

<head>

    <meta charset="UTF-8"/>

    <title>登录</title>

    <link rel="stylesheet" href="<%=request.getContextPath() %>/css/signin.css">

    <link rel="stylesheet" href="<%=request.getContextPath() %>/css/bootstrap.min.css">

    <style type="text/css">

        body {

            padding-top: 50px;

        }

        .starter-template {

            padding: 40px 15px;

            text-align: center;

        }

    </style>

</head>

<body>

<nav class="navbar navbar-inverse navbar-fixed-top">

    <div class="container">

        <div class="navbar-header">

            <a class="navbar-brand" href="#">Spring Boot+JSP</a>

        </div>

        <div id="navbar" class="collapse navbar-collapse">

            <ul class="nav navbar-nav">

            </ul>

        </div>

    </div>

</nav>

<div class="container">

    <div class="starter-template">

        <h2>登录</h2>

        <form class="form-signin" role="form" name="form" action="/login" method="post">

            <div class="form-group">

                <label for="username">用户名</label>

                <input type="text" class="form-control" name="username" value="" placeholder="用户名"/>

            </div>

            <div class="form-group">

                <label for="password">密码</label>

                <input type="password" class="form-control" name="password" placeholder="密码"/>

            </div>

            <input type="submit" id="login" value="Login" class="btn btn-primary"/>

        </form>

    </div>

</div>

</body>

</html>

8.引入css文件,这个不影响效果,只是index.jsp的页面会不好看

9.新建IndexController.java

package com.example.demo.controller;

import org.springframework.stereotype.Controller;

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

@Controller

public class IndexController {

    @RequestMapping("/index")

    public String index() {

        return "index";

    }

}

如果想使用restcontroller注解，需要以下处理

@GetMapping("/order")
public ModelAndView toPayJsp() {
// return
// "pay_wx";//@RestController注解含有@ResponseBody注解,结果pay_wx没有经过视图解析器解析直接变成json字符串返回给浏览器了
ModelAndView mv = new ModelAndView("pay_wx");
return mv;
}

10.启动服务,访问localhost:8080/index 即可访问index.jsp成功
