Spring Boot test class wont inject beans
提问by rayman
I am using the following dependencies:
我正在使用以下依赖项：
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')
Created new test class:
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");
}
}
I created test case inside Spring boot However i get this error:
我在 Spring boot 中创建了测试用例但是我收到了这个错误：
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)}
This is my application class:
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");
}
}
Any idea why I cant inject beans into my test class?
知道为什么我不能将 bean 注入我的测试类吗？
I removed @ContextConfiguration,@ComponentScan,@IntegrationTes as suggested Now I see different exception:
我按照建议删除了 @ContextConfiguration,@ComponentScan,@IntegrationTes 现在我看到了不同的异常：

just remove this part:
只需删除这部分：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
instead ,using this:
相反，使用这个：
