- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?

我正在尝试使用基于声明的 AOP 在 Spring 运行 JUnit 测试用例。当我运行测试时,我得到 ClassNotFound Exception (cleared) 和另一个异常 java.lang.IllegalStateException: Failed to load ApplicationContext 。异常看起来很简单,但我无法解决它。
它是一个 Junit 测试用例,因此不需要 main 方法,因为我没有运行客户端代码,测试用例不会运行。如果我错了,请告诉我。
谁能帮我解决这个错误,我尝试重建、清理构建项目、删除并重新添加所有可执行 jar 文件。
这是代码

最佳答案
IllegalStateException
只是抛出的“最高”异常,通知您 Spring 未能加载应用程序上下文,但您必须调查堆栈跟踪以找到此类异常的来源。在堆栈跟踪的底部,我们可以找到一个 NoSuchBeanDefinitionException
,其中包含一条错误消息:
No bean named 'audience' is defined
那么让我们检查一下您的 Spring 配置。
你有一个“Audience”bean 定义如下:
<bean id="Audience" class="declarativeBeans.Audience1" />
您要在此处将其称为“观众”:
<aop:aspect ref="audience">
您必须使用相同的 ID 命名相同的 bean(大小写),以便 Spring 能够正确引用(和注入(inject))它们。
