Question

我不确定说出这个问题的最好方法，因为我不知道为什么会这样。当我在没有spring-integration-core jar的情况下启动Spring Boot应用程序时，我的应用程序启动正常。第二个我将spring-boot-starter-integration或任何spring-integration-core库添加到我的Maven pom文件中，我的DelegatingWebMvcConfiguration类上的servlet上下文始终为null，我收到以下错误：

java.lang.IllegalArgumentException: A ServletContext is required to configure default servlet handling

在做了一些调试之后，我看到在DelegatingWebMvcConfiguration为我的应用程序设置servlet上下文之前初始化EmbeddedWebApplicationContext类，这对于为什么我的DelegatingWebMvcConfiguration的servlet上下文为空是有道理的为在postProcessBeforeInitialization中使用ServletContextAwareProcessor初始化的所有其他类设置。简单地删除Spring Integration依赖项就可以解决问题，但是我想在我的Boot应用程序中使用Spring Integration。

我的问题是在DelegatingWebMvcConfiguration调用EmbeddedWebApplicationContext方法之前导致prepareEmbeddedWebApplicationContext的原因是什么。

使用Spring Boot 1.1.8.RELEASE的Spring依赖项： org.springframework.boot 弹簧引导启动的Web

我的根配置文件：

   @EnableAutoConfiguration
   @EnableAsync
   @EnableEntityLinks
   @EnableSpringDataWebSupport
   @ComponentScan
   @PropertySource(value = "file:../application.properties",
        ignoreResourceNotFound = true)
   public class ApplicationInitializer extends SpringBootServletInitializer
        implements EmbeddedServletContainerCustomizer {
      public static void main(String[] args) throws Exception {
        SpringApplication.run(ApplicationInitializer.class, args);
      }

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

      @Override
      public void customize(ConfigurableEmbeddedServletContainer container) {
        container.setContextPath(APPLICATION_ROOT_PATH);
      }
      // Global beans defined here
  }

更新：在尝试了很多不同的事情后，我发现在禁用我的SchedulingConfigurer后，我的应用程序现在启动了。这是我的SchedulingConfigurer

@Configuration
@EnableScheduling
@EnableConfigurationProperties(SchedulingProperties.class)
public class SchedulingConfig implements SchedulingConfigurer {
    //Inject Runnables and properties

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.setScheduler(taskScheduler());
        // call taskRegistrar.addFixedRateTask with runnable and property rate value
    }

    @Bean(destroyMethod = "shutdown")
    public Executor taskScheduler() {
        ThreadPoolTaskScheduler taskScheduler = new ThreadPoolTaskScheduler();
        taskScheduler.setPoolSize(Runtime.getRuntime().availableProcessors());
        return taskScheduler;
    }
}
