SpringBoot项目打成war包，并部署到Tomcat服务器

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
