spring boot 打 war包

spring boot 、spring cloud打 war包，并发布到tomcat中运行

1、pom文件修改

<packaging>war</packaging>

2、<!-- 移除嵌入式tomcat插件 -->

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-tomcat</artifactId>
        </exclusion>
    </exclusions>
</dependency>

3、增加两个依赖(也许引入其中就够了，没测试)

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.apache.tomcat</groupId>
    <artifactId>tomcat-servlet-api</artifactId>
    <version>8.0.</version>
    <scope>provided</scope>
</dependency>

 

4、新增一个类或直接在Application类中继承SpringBootServletInitializer类并复写configure方法

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
/**
 *
* Copyright: Copyright (c) 2019 WuDG
*
* @ClassName: ServletInitializer.java
* @Description:将项目打包成war则需要集成SpringBootServletInitializer并复写configure方法
* @version: v1.0.0
* @author: WuDG
* @date: 2019/08/13 15:50

*/
public class ServletInitializer extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(DemoApplication.class);
    }
}

5、进入项目根目录，打开CMD终端，输入命令

mvn clean package

6、进入 target 目录下直接复制一份 war包放到tomcat中即可
