Mybatis 多个参数批量查询写法 <select id="queryUUidByPortName" parameterType="com.chinamoblie.cmss.idcbussiness.entity.QueryResource" resultType="map" > SELECT t1.uuid AS "originalResourceId", t1.zh_label AS "portName", t2.uuid AS "equipmentUUID", t2.zh_label AS "equipmentName" FROM cm_device_ip_idc t2, cm_port_ip_ptp_idc t1 where (t2.zh_label,t1.zh_label) in <foreach collection="list" item="item" open="(" close=")" separator=","> (#{item.equipmentName},#{item.portName}) </foreach> 执行如果卡住,看看是不是有锁表 select oid,relname from pg_class where relname='cm_device_core_nfv'; select locktype,database,pid,relation ,mode from pg_locks where relation='206761'; select * from pg_stat_activity where pid = '30046'; select pg_terminate_backend('30046');
