Wrapper 的where条件在xml使用

mapper.xml 
  select * from (
            SELECT a.*,
              b.`id` AS audit_id,
              IFNULL(b.`status`,0) AS audit_status,
              b.`reason` AS audit_reason,
              b.`create_time` AS audit_create_time,
              b.`create_by` AS audit_create_by,
              b.`audit_time`,
              b.`audit_by`,
              b.`dept_id`,
              b.`company_id`,
              IFNULL(d.short_name, d.dept_name) AS company_name
            FROM `xxx` a

            LEFT OUTER JOIN `xxx` d ON d.dept_id = b.`company_id`
        ) t
        ${ew.customSqlSegment}

mapper.java
