Junit测试service中的方法

package test;import javax.annotation.Resource;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.xmniao.xmn.core.common.service.FileService;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"classpath:com/xmniao/xmn/resource/config/spring-context.xml","classpath:com/xmniao/xmn/resource/config/spring-mvc-servlet.xml"}) // 加载配置 public class FastFileTest extends AbstractTransactionalJUnit4SpringContextTests {@Resourceprivate FileService fileService;@Testpublic void testFileDelete() {String file_id = "";int result = fileService.deleteFile(file_id);System.out.println(result);}}//1.读取配置文件在注解ContextCOnfiguration中,多个用,隔开。//2.注意相对路径（凡是出现不能实例化的都是 文件读取有问题)
