JUNIt中的测试应用程序

Question

在JUNIT中测试我的应用程序时出现错误

java.lang.IllegalStateException: Failed to load ApplicationContext

当我为Configuration创建类而不是为applicationContext文件创建类时，它弄乱了该错误。

下面是类和DAO文件。

        assertTrue(true);
    }
    @Test
    public void testRemoveUser() {

        assertTrue(true);

    }

}

作为即时消息使用类来配置而不是XML文件。是否有任何方法可以克服此错误，没有找到类型为[org.hibernate.SessionFactory]的合格Bean作为依赖项。

无法加载ApplicationContext是此错误的基本原因之一。这是配置文件中的完整代码详细信息

WebAppContext和TestContext是配置文件的
