在使用springMVC 和 mybatis 整合時，報如下錯誤：
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.wechatlearning.permission.service.RoleService.save at org.apache.ibatis.binding.MapperMethod$SqlCommand.<init>(MapperMethod.java:223) at org.apache.ibatis.binding.MapperMethod.<init>(MapperMethod.java:48) at org.apache.ibatis.binding.MapperProxy.cachedMapperMethod(MapperProxy.java:59) at org.apache.ibatis.binding.MapperProxy.invoke(MapperProxy.java:52) at com.sun.proxy.$Proxy20.save(Unknown Source) at com.wechatlearning.permission.controller.RoleController.aaa(RoleController.java:29) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.springframework.web.method.support.InvocableHandlerMethod.doInvoke(InvocableHandlerMethod.java:221) at org.springframework.web.method.support.InvocableHandlerMethod.invokeForRequest(InvocableHandlerMethod.java:136) at org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.invokeAndHandle(ServletInvocableHandlerMethod.java:110) at org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.invokeHandlerMethod(RequestMappingHandlerAdapter.java:832) at org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter.handleInternal(RequestMappingHandlerAdapter.java:743) at org.springframework.web.servlet.mvc.method.AbstractHandlerMethodAdapter.handle(AbstractHandlerMethodAdapter.java:85) at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java:961) at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:895) at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:967) at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:858)
在網上找到很多解決辦法，基本上都是檢查 namespace 是否寫錯這樣的辦法，檢查了N遍，也沒發現問題，後來終於在這裡找到解決辦法：

具體原因如下：
報錯的配置：
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.wechatlearning" />
</bean>修改後的配置：
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.wechatlearning.*.dao" /> </bean>
修改後不會再報錯，是因為前面的配置在掃描時把 service 也掃描進去了。
