SpringBoot项目如何打war包问题详解

<packaging>jar</packaging>
//修改为
<packaging>war</packaging>

<!--添加servlet-api的依赖,用来打war包 -->
<dependency>
	<groupId>javax.servlet</groupId>
	<artifactId>javax.servlet-api</artifactId>
	<scope>provided</scope>
</dependency>

<!--最终打成war包，排除内置的tomcat-->
<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>

@SpringBootApplication
public class MainApp {
	public static void main(String[] args) {
		SpringApplication.run(MainApp.class,args);
	}
}

@SpringBootApplication
public class SpringBootMytestApplication extends SpringBootServletInitializer {
	public static void main(String[] args) {
		SpringApplication.run(SpringBootMytestApplication.class, args);
	}
	
	@Override
	protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
		// 注意这里要指向原先用main方法执行的Application启动类
		return builder.sources(SpringBootMytestApplication.class);
	}
}
