若依微服务框架扩展业务数据权限
·
由于业务库和系统库是分开的，用户和部门都在系统库，但是业务库中的数据也想要数据权限控制，所以扩展系统原来的数据权限功能
前提是业务表中要有 user_id 字段 和 dept_id 字段
- LoginUser 实体增加两个字段
一个存储的是用户所在部门的子节点部门id
一个存储的是用户所在部门的所有父子级的节点部门id
/**
* 当前用户所在部门子节点id（含当前部门）
*/
private List<Long> deptChildrenIds;
/**
* 所属部门的所有部门节点id（含所属部门）
*/
private List<Long> effDeptChildrenIds;
-
在用户登录的接口中查询到对应的数据进行赋值（自行实现下接口）
这里赋值后LoginUser会存到缓存中，后面直接就可以采用SecurityUtils.getLoginUser() 拿到了，所以只要在这个之前给赋值就可以了
-
DataScope 注解增加业务表别名字段
/**
* 业务表的别名
* @return
*/
public String bAlias() default "";
4. DataScopeAspect 切片类增加相关逻辑

- 使用
在需要业务过滤的地方增加@DataScope( bAlias = "表别名，与sql中业务表的别名一致")
sql 中增加${params.bdataScope}
