## 错误 ##

使用SpringMvc进行项目开发，运行项目报错

### 详细错误 ###

由于笔者所获取的代码已经完成了Accout对象的相关开发，对于后续ClothingClassification开发，笔者直接复制Accout的相关代码，并更改类名后直接运行项目，控制台报错：

### 解决方案 ###

确保service层的接口实现类（即service包下的impl包下的类）所使用的Service注解名称不一致

### 原因 ###

笔者由于直接复制`AccountServiceImpl`相关代码，未更改Service注解名称，导致Spring框架抛出的异常——Spring的应用上下文中存在两个相同名称但不兼容的Bean定义。要解决这个问题，需要检查代码中的注解或XML配置，确保每个Spring服务组件都具有唯一的服务名称。
