title: Spring Boot test class wont inject beans
body: <p>I am using the following dependencies:</p>
  
  <pre><code>apply plugin: 'java'
  apply plugin: 'eclipse'
  apply plugin: 'idea'
  apply plugin: 'spring-boot'
  apply plugin: 'war'
  
   compile("com.caucho:resin-hessian:4.0.23")
      compile("mysql:mysql-connector-java")
      compile('org.springframework.boot:spring-boot-starter-web:1.2.0.RELEASE')
      compile("org.springframework.boot:spring-boot-starter-batch:1.2.0.RELEASE")
      compile("org.springframework.boot:spring-boot-starter-actuator")
      compile("javax.inject:javax.inject:1")
      compile('org.springframework.batch:spring-batch-admin-manager:1.3.0.RELEASE') {
          exclude module: 'slf4j-log4j12'
      }
      //SI
      compile("org.springframework.integration:spring-integration-core:$springIntegrationVersion")
      testCompile('org.springframework.boot:spring-boot-starter-test:1.2.0.RELEASE')
  </code></pre>
  
  <p>Created new test class:</p>
  
  <pre><code>@RunWith(SpringJUnit4ClassRunner.class)
  @SpringApplicationConfiguration(classes = Application.class)
  @WebAppConfiguration
  @IntegrationTest
  @ContextConfiguration(locations={"classpath:**/*.xml"})
  @ComponentScan({"com.mycompany.notification.processor.service"})
  public class DownloadFileTaskletTest  {
  
      @Autowired
       private DownloadFileTasklet downloadFileTasklet;
  
      @Test
      public void execute()
      {
          System.out.printf("test123");
  
      }
  }
  </code></pre>
  
  <p>I created test case inside Spring boot
  However i get this error:</p>
  
  <pre><code>org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batch.DownloadFileTaskletTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.mycompany.notification.processor.service.batch.tasks.DownloadFileTasklet batch.DownloadFileTaskletTest.downloadFileTasklet; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.mycompany.notification.processor.service.batch.tasks.DownloadFileTasklet] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
  </code></pre>
  
  <p>This is my application class:</p>
  
  <pre><code>@ComponentScan({"com.mycompany.notification.processor.service"})
  @EnableAutoConfiguration
  @Configuration
  @ImportResource({
          "classpath:integration-context.xml","classpath:launch-context.xml","classpath:applicationContext-NotificationProcessorService.xml"
  })
  //@Import({ ServletConfiguration.class, WebappConfiguration.class })
  public class Application {
      public static void main(String[] args) {
          SpringApplication.run(Application.class, args);
          System.out.printf("hello man");
      }
  
  }
  </code></pre>
  
  <p>Any idea why I cant inject beans into my test class?</p>
  
  <p>I removed @ContextConfiguration,@ComponentScan,@IntegrationTes as suggested
  Now I see different exception:</p>
