SpringBoot 2.x 使用外置 Servlet 容器（Tomcat）
1、项目结构
2、代码
- HelloController.java：
@Controller
public class HelloController {
@GetMapping("/abc")
public String hello(Model model){
model.addAttribute("msg","你好");
return "success";
}
}
- application.properties：
# 配置SpringMVC的视图解析
spring.mvc.view.prefix=/WEB-INF/
spring.mvc.view.suffix=.jsp
- success.jsp：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>SUCCESS</h1>
<h3>${msg}</h3>
</body>
</html>
- hello.jsp：
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<h1>Hello JSP</h1>
<a href="abc">abc</a>
</body>
</html>
pom.xml：
<properties>
<java.version>1.8</java.version>

3、配置
-
Project Structure：
-
Server：
-
Deployment：
4、运行
直接启动Tomcat报404错误，需要通过spring-boot:run运行。
注意上图，启动的端口并不是我配置的8081，那位知道可以告诉下。
http://localhost:8080/hello.jsp
