1: 创建spring boot项目

使用 Spring initializr  可以直接选择创建包的方式

也可以选择在Pom中更改

    <groupId>com.dgw</groupId>

    <artifactId>demo</artifactId>

    <version>0.0.1-SNAPSHOT</version>

    <packaging>war</packaging>

    <name>demo</name>

    <description>Demo project for Spring Boot</description>

2: 创建初始化类

使用 Spring initializr  自动已经为我们创建完成了, 当然可以选择手动创建下面的初始化器 继承 SpringBootServletInitializer

public class ServletInitializer extends SpringBootServletInitializer {

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(DemoApplication.class);

    }

}

2.1配置视图解析器访问路径

在application.properties 或者 yaml 下配置

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

spring.mvc.view.suffix=.jsp

3: 创建webapp目录

Spring Boot 在 Project Structure 中创建

 Web Resource 创建  这个路径

\src\main\webapp

Deployment Descriptors 创建web.xml

# 路径

\src\main\webapp\WEB-INF\web.xml

web.xml配置信息

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee"

           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"

           version="3.0">

</web-app>

正常创建的目录结构

4: 配置测试

创建控制器

@RestController

public class FisrtController {

    @GetMapping("/sayhi")

    public ModelAndView sayHi(){

        ModelAndView andView = new ModelAndView();

        andView.setViewName("success");

        andView.addObject("msg","HELLO");

        return andView;

    }

}

webapp 路径 创建index.jsp文件

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

<html>

<head>

    <title>Title</title>

</head>

<body>

        <a href="sayhi">send msg</a>

</body>

</html>

webapp\WEB-INF 下创建success.jsp

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

<html>

<head>

    <title>Title</title>

</head>

<body>

    <h2>${msg}</h2>

</body>

</html>

结果:

附录 POM:
