### 当前使用版本(必填,否则不予处理) 3.4.3.4 ### 该问题是如何引起的？(确定最新版也有问题再提!!!) right join on条件为非主键 right join 在on中添加了右表.tenant_id=xxx right join是通过where将右表筛选之后的数据全部查询出来, on中的条件只是筛选左表的数据, 这里无法做到筛选条件 ### 重现步骤(如果有就写完整) 代码为你们提供的用例: https://gitee.com/baomidou/mybatis-plus-samples/tree/master/mybatis-plus-sample-tenant 修改 src/main/java/com/baomidou/mybatisplus/samples/tenant/mapper/UserMapper.xml文件如下图所示  执行junit单测 com.baomidou.mybatisplus.samples.tenant.TenantTest#testTenantFilter 生成的sql为 ```sql SELECT a.name AS addr_name, u.id, u.name FROM user_addr a RIGHT JOIN user u ON u.name = a.name AND u.tenant_id = 1 ``` 期望的sql应该是 ```sql SELECT a.name AS addr_name, u.id, u.name FROM user_addr a RIGHT JOIN user u ON u.name = a.name AND a.tenant_id = 1 where u.tenant_id=1 ``` 期望查询的数据是3条, 实际查询了5条 ### 报错信息 无
