我使用 spring 为 JPA 编写了一个 JUnit 测试用例。测试用例在 eclips 中通过。但是，如果我使用 maven (mvn test) 执行相同的测试用例，它会失败。
我的测试用例是：
import javax.annotation.Resource;
import junit.framework.TestCase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:config/servicecontext-standalone.xml")
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = false)
@Transactional
public class UserServiceImplTest extends TestCase {
@Resource(name = "UserService")
private UserService userService;
public UserServiceImplTest() {
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
@Test
public void testFindUser() {
try {
UserFindRequest pUserFindRequest = new UserFindRequest();
pUserFindRequest.setUserId(1);
UserServiceImpl aUserServiceImpl = (UserServiceImpl) this
.getUserService();
aUserServiceImpl.findUser(pUserFindRequest);
System.out.println("Success");
} catch (Exception e) {
e.printStackTrace();
}
}
@Test
public void testCreateUser() {
try {
UserServiceImpl aUserServiceImpl = (UserServiceImpl) this
.getUserService();
UserPersistRequest pUserPersistRequest = new UserPersistRequest();
UserDto pUserDto = new UserDto();
pUserDto.setUserId(6L);
pUserDto.setName("JUnit 6");
pUserPersistRequest.setUserDto(pUserDto);
aUserServiceImpl.createUser(pUserPersistRequest);
System.out.println("Persist Success");
} catch (Exception e) {
e.printStackTrace();
}
}
}
和 servicecontext-standalone.xml 文件是
