mybatis 遍历map实例
map 数据如下 Map<String,List<Long>>.
测试代码如下:
public void getByMap(){ Map<String,List<Long>> params=new HashMap<String, List<Long>>(); List<Long> orgList=new ArrayList<Long>(); orgList.add(10000003840076L); orgList.add(10000003840080L); List<Long> roleList=new ArrayList<Long>(); roleList.add(10000000050086L); roleList.add(10000012180016L); params.put("org", orgList); params.put("role", roleList); List<BpmDefUser> list= bpmDefUserDao.getByMap(params); System.out.println(list.size()); }
dao代码如下:
public List<BpmDefUser> getByMap(Map<String,List<Long>> map){ Map<String,Object> params=new HashMap<String, Object>(); params.put("relationMap", map); return this.getBySqlKey("getByMap", params); }
xml代码如下:
<select id="getByMap" resultMap="BpmDefUser"> <foreach collection="relationMap" index="key" item="ent" separator="union"> SELECT * FROM BPM_DEF_USER where RIGHT_TYPE=#{key} and OWNER_ID in <foreach collection="ent" item="id" separator="," open="(" close=")"> #{id} </foreach> </foreach> </select>
