-使用

-```java
-/**
- * 一对一，一对多关系映射查询
- * 如果不需要关系映射就使用mybatis plus原生方法即可，比如 getById listByIds 等
- * <p>
- * 注意：关系映射不会去关联查询，而是执行多次单表查询（对结果汇总后使用in语句查询,再对结果进行匹配）

-MPJMapping 说明：
-
-* @EntityMapping / @FieldMapping tag 关联实体类
-* @EntityMapping / @FieldMapping thisField 当前类关联对应的字段的属性名，可以不填，默认为当前类的主键
-* @EntityMapping / @FieldMapping joinField 关联类对应的字段的属性名，可以不填，默认为关联类的主键
-* @EntityMapping / @FieldMapping isThrowExp 一对一查询时,如果查询到多条记录是否抛出异常,true:抛出异常,false:获取列表第一条数据
-*
