/**
 * 该注解应用在 Mapper 的查询接口上，当 Mapper 查询接口未指定任何结果集映射的时候
 * 该注解将会根据 Mapper 的泛型T来生成一个 {@link org.apache.ibatis.mapping.ResultMap}
 * 对象去覆盖 {@link org.apache.ibatis.mapping.MappedStatement} 原有的
 * {@link org.apache.ibatis.mapping.ResultMap} 对象
 *
 * 
请确保 {@link AutoResultMap} 使用于查询接口，且返回值为一个POJO对象或{@link java.util.Collection}
 * 不然将无法生成 {@link org.apache.ibatis.mapping.ResultMap} 对象
