AnnotatedElementUtils错误Spring测试

Question

我写了一个jUnit测试，但我在执行它时遇到了错误：

我的应用程序是这样配置的：

我的测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("TestDao-context.xml")
public class TestDao {
@Autowired
private Dao test;


@Test
public void test() {
    Dao test = new DaoImpl();
    try {
        test.connect();
        assertTrue(true);
    } catch (UnknownHostException e) {
        e.printStackTrace();
        assertTrue(false);
    }
}
}

我的上下文配置：

    <?xml version="1.0" encoding="UTF-8"?>

我的网络。xml配置：

根据网络上的不同教程，配置似乎很好，但我不知道错误来自哪里。

我认为TestDao是一个上下文。我的测试类没有很好地实现xml，因为当我将上下文文件移动到另一个项目时，错误根本不会改变。此外，我测试了许多不同的方法来配置@ContextConfiguration，但它没有改变任何东西。

你看出什么不对劲了吗？

Answer 1

为了解决这个问题，我所做的就是更新我的pom配置：我升级了Spring test（4.0.0. RELEASE）和JUnit的版本。

Answer 2

实际问题是spring-test和其他spring-*jar版本之间不一致（可能3. x. x和4. x. x彼此不兼容。）任何无法遇到此问题的人都可以对所有Spring依赖项使用相同的Spring版本。
