spring boot war 启动 springboot war包启动

之前我们讲了SpringBoot的jar包方式启动，这里进行war包部署讲解，与传统的部署方式大致一样，传统mvc项目maven热部署方式请看我之前的博客 

1.war包部署首先在pom文件中将打包方式改成war

<!-- 打包方式 -->
 <packaging>war</packaging>

2.加上打包的项目名称(没什么卵用):

<!-- 打包的项目名称 -->
<finalName>springbootdemo</finalName>

 3.修改启动类,继承SpringBootServletInitializer类并重写configure(）方法:

package com.qzsun.springbootdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

import javax.swing.*;

@SpringBootApplication
public class SpringbootdemoApplication extends SpringBootServletInitializer {
    //打成war包需要继承SpringBootServletInitializer并重写configure方法
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SpringbootdemoApplication.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SpringbootdemoApplication.class, args);
    }

}

4.加一个controller进行测试:

@Controller
public class IndexController {

    @RequestMapping("/index")
    @ResponseBody
    public Map<String, Object> index(){
        System.out.println("热部署1");
        Map<String,Object> map = new HashMap<>();
        map.put("name","张三");
        map.put("age",18);
        return map;
    }
}

5.使用maven 命令打一个war包(mvn install),然后将war包丢到tomcat的wepapps目录中，在bin目录下启动startup.bat

6.访问接口成功(这里我修改了tomcat的端口号为8081),
