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

<dependency>
    <groupid>javax.servlet</groupid>
    <artifactid>javax.servlet-api</artifactid>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupid>org.apache.tomcat</groupid>
    <artifactid>tomcat-servlet-api</artifactid>
    <version>8.0.36</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);
    }
}
