1. 將項目的打包方式改為war包

<groupId>com.cc</groupId>
<artifactId>aaaaaa</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>

2. 排除內置tomcat

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided
 
</scope>
</dependency>

3. 編寫一個SpringBootServletInitializer的子類，調用config方法

public class ServletInitializer extends SpringBootServletInitializer {

    /**
     * Configure the application. Normally all you would need to do is to add sources
     * (e.g. config classes) because other settings have sensible defaults. You might
     * choose (for instance) to add default command line arguments, or set an active
     * Spring profile.
     *
     * 
 
@param builder a builder for the application context
     * @return the application builder
     * @see SpringApplicationBuilder
     */
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
　　　　　//傳入springboot應用程序的主程序
        return builder.sources(NetworkingAuditManagementApplication.class
 
);
    }
}

重要：

你也可以在創建項目的時候就直接打成war包！

springboot將項目打成war包
