1 步骤
1.1 创建war项目
1.2 将内置Tomcat指定为provided

1.3 SpringBootServletInitializer的子类必须存在,并调用configure方法
package com.gp6.springboot22;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Springboot22Application.class);
}
}
1.4 配置外部tomcat
1.5 新建测试页面
- test.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Test</title>
</head>
<body>
<h1>测试 JSP</h1>
<a href="test">点击看看</a>
</body>
</html>
1.6 Controller
package com.gp6.springboot22.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HelloController {
@GetMapping("/test")
public String hello(Model model){
model.addAttribute("msg","看什么?6,你和我,走一波!");
return "success";
}
}
1.7 application.properties
spring.mvc.view.prefix=/WEB_INF/
spring.mvc.view.suffix=.jsp
1.8 测试
http://localhost:8082/test.jsp
