查询部门下面的用户 及子部门下面用户
cnd条件为

cnd.where().andInBySql("dept_id","SELECT dept_id FROM sys_dept  WHERE FIND_IN_SET ('%%%s%%',ancestors)", deptId).or("dept_id","=", deptId);

输出SQL为

 For example:> "SELECT * FROM sys_user  WHERE dept_id IN (SELECT dept_id FROM sys_dept  WHERE FIND_IN_SET ('%100%',ancestors)) OR dept_id='100' LIMIT 0, 10 "

改成酱紫 报错

cnd.where().andInBySql("dept_id","SELECT dept_id FROM sys_dept  WHERE FIND_IN_SET ('%%s%',ancestors)", deptId).or("dept_id","=", deptId);
 org.nutz.service.EntityService.<init>(EntityService.java:41) - Get TypeParams for self : io.nutz.nutzsite.module.sys.models.User

想要 sql输出 为

SELECT dept_id FROM sys_dept  WHERE FIND_IN_SET ('100',ancestors)

那是String.format,

\% 转义一下

完美解决

cnd.where().andInBySql("dept_id","SELECT id FROM sys_dept  WHERE FIND_IN_SET ('%s',ancestors)", deptId).or("dept_id","=", deptId);
