当表中的id为bigint类型，并且要通过id的数组来查询数据时，此时id的数组不能是字符串数组String[]而应该是Long[],此时就需要将字符串数组转换成Long类型数组
String[] inDetailIdsString = inDetailIdString.split(","); //string 转为 long List<Long> inDetailIds = Arrays.stream(inDetailIdsString) .map(s -> Long.parseLong(s.trim())).collect(Collectors.toList());
...
int count4 = inStoreDetailDao.queryCountByCurCodeAndDetailId(inStoreCodeTab, curcode, inDetailIds);
dao接口
int queryCountByCurCodeAndDetailId(@Param("inStoreCodeTab") String inStoreCodeTab, @Param("curcode") String curcode, @Param("inDetailIds") List<Long> inDetailIds);
mapper.xml
<select id="queryCountByCurCodeAndDetailId" resultType="int"> select count(*) from ${inStoreCodeTab} <where> <if test="curcode!=null and curcode!=‘‘"> AND CURCODE = #{curcode} </if> <if test="inDetailIds!=null and inDetailIds.size()>0"> <foreach collection="inDetailIds" open=" and IN_DETAIL_ID in( " close=")" item="id" separator=","> #{id} </foreach> </if> </where> </select>
