Consider defining a bean of type 'com.mlex.mapper.AdminMapper' in your configuration

这个错误提示是说在配置中没有找到类型为'com.mlex.mapper.AdminMapper'的bean。解决这个问题可以考虑以下几个方法：

1. 配置bean: 在你的配置文件中添加一个bean定义，指定类型为'com.mlex.mapper.AdminMapper'。这样spring就可以找到并注入这个bean了。

2. 使用@Mapper注解: 在你的AdminMapper类上添加@Mapper注解，这样spring就会自动扫描并生成AdminMapper的bean，并注入到相关的Service中。这样你就不需要在配置文件中设置扫描地址了。

3. 使用@ComponentScan注解: 在你的主程序上添加@ComponentScan注解，并指定需要扫描的文件夹路径。这样spring就会自动扫描指定文件夹下的所有组件，并生成相应的bean注入到Service中。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
