單元測試使用spring注解獲取bean

在實際項目開發中經常會有單元測試,單元測試中經常會用類似這樣的代碼片段獲取spring管理的bean

@Test
public void testSendEmail(){
		MessageService messageService = (MessageService) BeanFactory.getInstance().getBean("messageService");
		messageService.send();
}

　這樣既不美觀,又比較繁瑣,spring引進了spring-test跟junit結合使用可以方便的得到spring bean

　因為在項目中適用maven管理依賴,先在pom.xml中添加依賴

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>${spring.version}</version>
</dependency>

　綁定spring配置文件路徑

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class BaseTest extends TestCase {
    protected Logger logger = LoggerFactory.getLogger(getClass());

}
在單元測試類中集成 BaseTest

public class PostServiceTest extends BaseTest {
@Resource(name = "postService")
private PostService postService;

@Test
public void testQuery2LevelPostType() {
Map<Integer,Object> map= postService.query2LevelPostType();
System.out.println("data size:" + map.size());
　　}
}

這樣就可以在單元測試中輕松獲取spring bean了,減少了繁瑣的代碼也增強了代碼的可讀性
