Spring / JPA數據在單元測試中持續存在但不在應用程序中

Question

我無法通過調用我的userService在我的Spring / JPA / Tomcat應用程序中保存數據，但是當我從單元測試中調用它時，數據將被寫入數據庫。 從我的控制器調用服務時也沒有拋出任何異常。

控制器類：

@Controller
@RequestMapping("/")
public class AccessManagementController {

    @Autowired
    private UserService userService;

    @Autowired
    private ApplicationProperties applicationProperties;

    @RequestMapping(method = RequestMethod.GET, value = "/register")

        :
        :
        :

        userService.createNewUser(username, password);

        model.addAttribute("loginMessage", "Registration successful; you can now login");
        return "/access";
    }
}

工作單位測試：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
        "classpath:/spring/applicationContext.xml",
        "classpath:/spring/securityContext.xml",
        "classpath:/spring/jpaContext.xml"
})
public class UserServiceTest {

    @Autowired
    private UserService userService;

    @Test
    public void userServiceSaveUserTest() {

        String testUsername = (new Date()).toString();

        userService.createNewUser(testUsername, "password");
        User findUser = userService.findByUsername(testUsername);
        Assert.assertNotNull(findUser);
        Assert.assertEquals(findUser.getUsername(), testUsername);
    }
}

applicationContext.xml中：

Answer 1

1。 你不需要

<bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/>

這里的解釋：

http://static.springsource.org/spring/docs/2.5.6/api/org/springframework/orm/jpa/support/PersistenceAnnotationBeanPostProcessor.html

注意：默認的PersistenceAnnotationBeanPostProcessor將由“context：annotation-config”和“context：component-scan”XML標記注冊。 如果要指定自定義PersistenceAnnotationBeanPostProcessor bean定義，請刪除或關閉默認注釋配置。

2。 嘗試將@Transactional添加到UserService.createNewUser（）。
