嗨，我正在尝试将我的 DaoTest 类测试为 junit 测试。在运行该类时，我得到：

java.lang.NoClassDefFoundError: org/springframework/beans/factory/NoUniqueBeanDefinitionException。

我查看了互联网，发现这可能不仅仅是因为在配置文件中引用了您的 bean。但我无法弄清楚我如何对豆类有不止一个参考。

这里是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：

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