maven+mybatis+spring在开发的时候，遇到如下错误：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name ‘xxxService’: Unsatisfied dependency expressed through field ‘xxxMapper’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘xxxMapper’ defined in file [xxxMapper.class]: Cannot resolve reference to bean ‘sqlSessionFactory’ while setting bean property ‘sqlSessionFactory’; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘sqlSessionFactory’ defined in class path resource [xxx-mybatis.xml]: Initialization of bean failed; nested exception is org.springframework. beans.TypeMismatchException: Failed to convert property value of type ‘Java.lang.String’ to required type ‘org.springframework.core.io.Resource[]’ for property ‘mapperLocations’; nested exception is java.lang.IllegalArgumentException: Could not resolve resource location pattern [classpath:com/xxx/xxx/mapping/*.xml]: class path resource [com/xxx/xxx/mapping/] cannot be resolved to URL because it does not exist

经过检查发现maven编译后并没有将xml文件打包到输出路径，导致bean创建失败。

因此解决方法就是在pom文件中添加如下代码：

    ...
    
        
        
            src/main/java
            
                **/*.xml
            
            true
        
    
    ...
