Spring application - Illegal state exception
提问by user3397211
I am trying to run a JUnit test case in spring using declarative based AOP. When i run the test i get ClassNotFound Exception (cleared) and one more exception java.lang.IllegalStateException: Failed to load ApplicationContext. The exception seems simple but I am not able to resolve it.
我正在尝试使用基于声明的 AOP 在 spring 中运行 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。
Its a Junit test case so main method is not required as I am not running a client code, the test case doesn't run. IF i am wrong let me know.
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，测试用例没有运行。如果我错了，请告诉我。
Can someone help me resolving this error, I tried to rebuild, clean build project, deleted and re-added all the executable jar files.
有人可以帮我解决这个错误，我尝试重建、清理构建项目，删除并重新添加所有可执行的 jar 文件。
Here is the code

The IllegalStateExceptionis merely the "topmost" exception thrown to inform you that Spring failed to load the application context but you have to investigate the stack trace to find the origin of such exception. At the bottom the stack trace, we can find a NoSuchBeanDefinitionExceptionwith an error message stating :
这IllegalStateException只是抛出的“最顶层”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，我们可以找到一条NoSuchBeanDefinitionException错误消息，说明：
No bean named 'audience' is defined
未定义名为“观众”的 bean
So let's check your Spring configuration.
因此，让我们检查一下您的 Spring 配置。
Your have an "Audience" bean defined as follow :
您有一个“受众”bean 定义如下：
<aop:aspect ref="audience">
that you're trying to reference as "audience" here :
您在此处尝试将其称为“观众”：
##代码##You must name the same bean with the same id (case matters) for Spring to be able to reference (and inject) them properly.
您必须使用相同的 id（大小写问题）命名同一个 bean，以便 Spring 能够正确引用（和注入）它们。

Change the package name as follow: "declarativeBeans.test" --> "declarativebeans.test" and try again. Note that in java convention, uppercase is not allowed in package name.
将包名更改如下："declarativeBeans.test" --> "declarativebeans.test" 然后再试一次。请注意，在 Java 约定中，包名中不允许使用大写字母。
