spring - AnnotatedElementUtils错误 Spring 测试

Question

我编写了一个 jUnit 测试，但在执行时出现错误:

我的应用是这样配置的:

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"?>

    </bean>

<!-- Tests -->
    <bean id="testDao" class="testdao.TestDao">
        <property name="test" ref="dao"/>
    </bean>

</beans>

我的 web.xml 配置:

    <?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"

         id="WebApp_ID" version="2.5">

        <servlet-name>dispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

根据网上的不同教程配置好像不错，但是不知道哪里出错了。

我认为我的测试类没有很好地实现 TestDao-context.xml，因为当我将上下文文件移动到另一个项目时，错误根本没有改变。 此外，我测试了很多不同的方式来配置我的@ContextConfiguration，它没有改变任何东西。

你看到哪里不对了吗？

实际问题是 spring-test 和其他 spring-* jar 版本之间的不一致(可能 3.x.x 和 4.x.x 彼此不兼容。)任何不会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.
