Question

您好我正在尝试将我的DaoTest课程作为junit考试进行测试。我在课程中运行：

java.lang.NoClassDefFoundError：组织/ springframework的/豆类/工厂/ NoUniqueBeanDefinitionException。

我查看了互联网，发现这可能不仅仅是因为配置文件中对bean的引用。但我无法弄清楚我如何有多个bean的引用。

这是UserDaoTest类：

@ContextConfiguration (locations = "classpath:persistence-beans.xml")
public class UserDaoTest extends DomainAwareBase {

@Autowired
@Qualifier("userDao")
private UserDao userDao;

@Test
public void testUpdate() {

    int size = userDao.list().size();

    User user = new User(1, "jimmy", "password", "admin", "sales");

    userDao.add(user);

    Assert.assertTrue(size < userDao.list().size());

}

@Test
public void testFind() {
    User user = new User(1, "jimmy", "password", "admin", "sales");

    userDao.add(user);
    User found = userDao.find(user.getUserId());

    Assert.assertEquals(user, found);
}

@Test
public void testList() {
    Assert.assertEquals(0, userDao.list().size());
    User user1 = new User(1, "jimmy", "password", "admin", "Sales");
    User user2 = new User(2, "pankit", "pankit", "admin", "HR");
    User user3 = new User(3, "abc", "abc", "admin", "Engineer");

    List<User> users = Arrays.asList(user1, user2, user3);

    for (User user : users) {

        userDao.add(user);
    }

    List<User> found = userDao.list();
    Assert.assertEquals(3, userDao.list().size());

    for (User user : found) {

        Assert.assertTrue(users.contains(user));

    }

}

@Test
public void testRemove() {

    User user1 = new User(1, "jimmy", "password", "admin", "Sales");

    userDao.add(user1);
    Assert.assertEquals(user1, userDao.find(user1.getUserId()));

    userDao.remove(user1);
    Assert.assertNull(userDao.find(user1.getUserId()));


}

}

这是我的persistence-beans.xml：

    </property>

    <property name="hibernateProperties">

            <prop key="hibernate.show_sql">true</prop>

            <prop key="hibernate.hbm2ddl.auto">update</prop>

        </props>

    </property>

</bean>

的修改这是我的堆栈跟踪

Answer 1

类NoUniqueBeanDefinitionException在您的类路径中不存在。将 spring-beans 依赖项/ jar包含到测试类路径中，然后重试。

在spring中测试dao测试类时出现NoUniqueBeanDefinitionException
