2. 排查分析
用 Spring AOP 写了一个日志管理，但是执行测试用例时，抛出异常，且提示：通配符的匹配很全面, 但无法找到元素 'aop:aspectj-autoproxy' 的声明。
后来发现，在 testApplicationContext.xml 文件中，文件头 xsi:schemaLocation 未加入 aop 的 xsd 文件：
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd
3. 解决方案
在 testApplicationContext.xml 文件中确保文件头有引入以下两个AOP文件，没有的话加上即可：
1）xmlns:aop="http://www.springframework.org/schema/aop"
2）http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd
修改后如下：
4. 番外物语
proxy-target-class="true" 与 proxy-target-class="false" 的区别：
- proxy-target-class：属性值决定是基于接口的还是基于类的代理被创建
- proxy-target-class="true"：基于类的代理将起作用（这时需要 CGLIB 库）
- proxy-target-class="false"：设置为false或者这个属性被省略，那么标准的 JDK 基于接口的代理将起作用
- 即使你未声明 proxy-target-class="true"，但运行类没有继承接口，spring 也会自动使用 CGLIB 代理。高版本 spring 自动根据运行类选择 JDK 或 CGLIB 代理
