环境版本说明
JDK13，tomcat9，springframework 2.2.4.RELEASE
一.pom文件修改
将packaging中改成war
二.排除内置的Tomcat容器
<!--声明spring boot内嵌tomcat的作用范围 在运行时不起作用-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
三.启动类中继承SpringBootServletInitializer，并实现configure方法
@SpringBootApplication
public class DemoApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication.class);
}
}
四.添加测试控制器
package com.example.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping("/demo")
public class DemoController {
@GetMapping("test")
@ResponseBody
public String getTest(){
return "Test Success";
}
}
五.执行Maven install，并将生成的war拷贝到tomcat下webapps目录中
六.运行tomcat后，访问路径
注意：访问路径要一定要加上项目名称(即:下面连接的demo-1.0.0的名称
http://localhost:8080/demo-1.0.0/demo/test
