春天开机测试类我使用下面的依赖不会注入豆

Question

：

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') 

创建新的测试类：

@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"); 

    } 
} 

我创建春天开机 内部测试情况，但是我得到这个错误：

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)} 

这是我的应用程序类：

@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"); 
    } 

} 

任何想法，为什么我不能将bean注入我的测试类？

我删除@ ContextConfiguration，@ ComponentScan，@ IntegrationTes的建议 现在我看到不同的异常：

只是删除这一部分：

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-test</artifactId> 
    <version>3.2.13.RELEASE</version> 
</dependency> 

相反，使用这样的：

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