禁用嵌入式servlet加载

Question

我有一个使用Spring Boot开发的批处理应用程序.我的批处理应用程序需要依赖关系spring-boot-starter-web.具体来说,我需要一个REST客户端spring-hateoas和jackson-databind支持.如何禁用嵌入式Tomcat启动？我需要使用什么排除？

@EnableAutoConfiguration(excludes = {
   /** What do I need to put here? */
})
@EnableBatchProcessing
@EnableConfigurationProperties
@ComponentScan
public class MyBatchApplication {
  public static void main(String... args) {
    SpringApplication.run(MyBatchApplication.class, args);
  }
}

至少,这些还不够,因为它以一个例外结束:

@EnableAutoConfiguration(exclude = {
  EmbeddedServletContainerAutoConfiguration.class,
  WebMvcAutoConfiguration.class,
  EmbeddedTomcat.class,
  DispatcherServletAutoConfiguration.class
})

例外是:

org.springframework.context.ApplicationContextException: Unable to start embedded container; nested exception is org.springframework.context.ApplicationContextException: Unable to start EmbeddedWebApplicationContext due to missing EmbeddedServletContainerFactory bean.

Answer 1

您可以在创建应用程序时明确禁用Web支持.这意味着您不需要排除任何自动配置:

@EnableAutoConfiguration
@EnableBatchProcessing
@EnableConfigurationProperties
@ComponentScan
public class MyBatchApplication {
    public static void main(String... args) {
        new SpringApplicationBuilder(MyBatchApplication.class).web(false).run(args);
    }
}
