提示：这里描述项目中遇到的问题：
spring中出现Error creating bean with name ‘X X’ defined in class path resource
使用spring配置aop编写出现下面错误

原因分析：

问题翻译：创建在类路径资源[applicationContext.xml]中定义了名为“userService”的bean时出错：bean初始化失败；嵌套的例外是java。lang.NoClassDefFoundError:org/springframework/core/NativeDetector
出现原因：
1、配置问题，spring中的配置文件写错了
2、注入问题，注入代码或者有参注入没有构造/set函数
3、依赖/架包影响

解决方案：

前两个原因无非是检查配置注入的代码，这个细心点容易找出来，我出现的问题卡了快一天，人都找麻了，结果是依赖影响的
我的这个模块项目中的bean注册不是用的注解，直接在xml中配置bean的，但是在项目中的pox.xml是导入了下面这个依赖
