springBoot生成war包

 

springBoot默认的打包方式为jar，要改成war包需要进行以下配置：

1.在pom.xml文件中声明打包方式：

<packaging>war</packaging>

2.移除springBoot内置的tomcat

<!-- 打包war [2] 移除自带内置tomcat -->
<exclusions>
    <exclusion>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <groupId>org.springframework.boot</groupId>
    </exclusion>
</exclusions>   

3.添加依赖

<!--打war包【3】 添加依赖-->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <scope>provided</scope>
</dependency>

4.编写war包启动类

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
// 打war包4  增加war包启动类
public class WarStartApplication extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(Application.class);
    }
}

5.安装 install ，war包在target包下
