关于bean无法注入

错误代码

Error creating bean with name 'roleServiceImpl' defined in file [/Users/tai_master/IdeaProjects/SecondHandHouse/web-admin/target/classes/com/qiushui/service/imp/RoleServiceImpl.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.qiushui.dao.RoleDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {} 

如何解决： spring-mapper导入扫描约束出错，重新修改约束

javax.servlet.ServletException: org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.qiushui.dao.RoleDao.findAll    at org.eclipse.jetty.server.handler.HandlerCollection.handle (HandlerCollection.java:146)    at org.eclipse.jetty.server.handler.HandlerWrapper.handle (HandlerWrapper.java:132)    at org.eclipse.jetty.server.Server.handle (Server.java:502)    at org.eclipse.jetty.server.HttpChannel.handle (HttpChannel.java:370)    at org.eclipse.jetty.server.HttpConnection.onFillable (HttpConnection.java:267)

解决问题：写错了方法

解决办法： 页面requestMapping写错
