idea 创建的maven+spring+mybatis项目整合 报错无法创建bean

报错如下：

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: public com.wolf.dao.IUserDao com.wolf.service.impl.IUserServiceImpl.udao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.wolf.dao.IUserDao] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

一直是不能创建bean的样子，经过检查发现mybatis的映射xml文件居然没有找到，发现classes目录果然没有*.xml，在pom文件中加入了如下代码，问题成功解决。

<build>
 
      <resources>
        <!--编译之后包含xml-->
        <resource>
          <directory>src/main/java</directory>
          <includes>
            <include>**/*.xml</include>
          </includes>
          <filtering>true</filtering>
        </resource>
      </resources>
 
  </build>
