Spring结合Junit单元测试

在实际项目开发中经常会有单元测试,单元测试中经常会用类似这样的代码片段获取spring管理的bean

@Test

public void testSendEmail(){

        MessageService messageService = (MessageService) BeanFactory.getInstance().getBean("messageService");

        messageService.send();

}

　这样既不美观,又比较繁琐,spring引进了spring-test跟junit结合使用可以方便的得到spring bean

　因为在项目中适用maven管理依赖,先在pom.xml中添加依赖

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-test</artifactId>

<version>${spring.version}</version>

</dependency>

　绑定spring配置文件路径

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = { "classpath:applicationContext.xml" })public class BaseTest extends TestCase {    protected Logger logger = LoggerFactory.getLogger(getClass());}
在单元测试类中集成 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());
　　}
}

这样就可以在单元测试中轻松获取spring bean了,减少了繁琐的代码也增强了代码的可读性
