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:
<?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"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
