Autowired注入dao失败

配置如下，一直报错：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userService': Unsatisfied dependency expressed through field 'userDao'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.lrto.module.dao.UserDao' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}，求各位大神指教

mapperlocations value ="classpath*:mapping/*.xml" 这样写试一下

UserDao.xml 里 resulttype 应该写全类名把

那个接口UserDao 不需要加注解吧

namespace路径错误吧
