是否需要web.xml来部署Spring引导应用程序

Question

我试图将弹簧启动应用程序打包为战争.根据这个,我修改了应用程序类:

@SpringBootApplication
@EntityScan({"org.mdacc.rists.cghub.model"}) 
@EnableJpaRepositories(basePackages = {"org.mdacc.rists.cghub.ws.repository"})
public class Application extends SpringBootServletInitializer
{

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

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

还在我的pom.xml中添加了以下内容

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

当我打包项目时,我收到以下错误:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.2:war (default-war) on project cg-web: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]

当我阅读spring boot应用程序时,我从未见过有关创建web.xml的任何内容.将Spring启动应用程序部署为战争需要web.xml吗？

Answer 1

根据这个答案,Maven通过将以下代码段添加到您的pom.xml来忽略web.xml缺席:

<plugin>
  <artifactId>maven-war-plugin</artifactId>
  <version>2.6</version>
  <configuration>
    <failOnMissingWebXml>false</failOnMissingWebXml>
  </configuration>
</plugin>
