SpringBoot发布war文件

首先必须修改启动类如下:

// 其他import本文中省略
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

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

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

}

在pom.xml中修改打包方式为war

<packaging>war</packaging>

在依赖中指定spring-boot-starter-tomcat为provided

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