Question

我正在尝试使用org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate批量更新表。 namedParameterJdbcTemplate.batchUpdate（query ...）方法; 我的查询包含子句，因此我收到如下SQL错误：

nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][1091][10824][4.14.113] Invalid data conversion: Parameter instance [1271, 1272] is invalid for the requested conversion. ERRORCODE=-4461, SQLSTATE=42815.

下面是我要批量更新的数据。它是contractId（String）的映射作为键，值是taskids列表（整数）数据：

{10008=[1271, 1272], 10007=[1269, 1270], 10009=[1273, 1274], 10011=[1277, 1278], 10010=[1275, 1276], 10012=[1279], 10006=[1267, 1268]}

where key is the CONTRACT_ID (String) and value is list of TASK_ID ( Integer)
e.g. CONTRACT_ID are 10008, 10007, 10009 etc.
and respective TASK_ID are [1271, 1272], [1269, 1270], [1273, 1274] etc.

我尝试在循环内调用namedParameterJdbcTemplate.update，并且工作正常，我可以使用单个更新来更新同一查询

单次更新

@Override
public int assignUserTask(String customerId, String userId, Map<String, List<Integer>> resultMap)
        throws ApplicationException {

    int totalCount = 0;
    String ts = DateUtils.getCurrentDatetimeStamp();
    String todaysDate = DateUtils.getTodaysDate();

    String query = CommonUtils.buildQuery("UPDATE EM_WF_USER_QUEUE SET", "CURRENT_USER_ID = :currentUserId,",
            "INITIAL_USER_ID = :initialUserId,", "USER_REASSIGN_TYPE_CD = 'GW',",
            "USER_REASSIGN_TIME = :userReassignTime,", "LAST_CENTRAL_QUEUE_DATE = :lastCentralQueueData,",
            "REASSIGN_CENTRAL_DATE = :reassignCentralDate,", "ORG_GW_CRT_TIME = :orgGwCreateTime,",

            "AND OVERIDE_IND = 'N' AND QUEUE_STATUS != 'CLOSED'");

    try {

        MapSqlParameterSource params = new MapSqlParameterSource();
        params.addValue("currentUserId", userId);
        params.addValue("initialUserId", userId);
        params.addValue("userReassignTime", ts);
        params.addValue("lastCentralQueueData", todaysDate);
        params.addValue("reassignCentralDate", todaysDate);
        params.addValue("orgGwCreateTime", ts);
        params.addValue("lastUpdtUser", userId);
        params.addValue("lastUpdtTime", ts);
        params.addValue("customerId", customerId);

        for (Entry<String, List<Integer>> entry : resultMap.entrySet()) {
            params.addValue("contractId", entry.getKey());
            params.addValue("taskIds", entry.getValue());

            totalCount += namedParameterJdbcTemplate.update(query, params);
        }
        return totalCount;

    } catch (DataAccessException exp) {
        throw new CustomException(exp, "Exception occured!");
    }

@Override 公共诠释assignUserTask（字符串customerId，字符串userId，地图> resultMap）引发CustomException {

    String ts = DateUtils.getCurrentDatetimeStamp();
    String todaysDate = DateUtils.getTodaysDate();

    String query = CommonUtils.buildQuery("UPDATE EM_WF_USER_TASK SET", "CURRENT_USER_ID = :currentUserId,",
            "INITIAL_USER_ID = :initialUserId,", "USER_REASSIGN_TIME = :userReassignTime,",
            "LAST_CENTRAL_QUEUE_DATE = :lastCentralQueueData,", "REASSIGN_CENTRAL_DATE = :reassignCentralDate,",
            "ORG_GW_CRT_TIME = :orgGwCreateTime,", "LAST_UPDT_USER = :lastUpdtUser ,",
            "LAST_UPDT_TIME = :lastUpdtTime", "WHERE CONTRACT_ID = :contractId AND TASK_ID IN (:taskIds)",
            "AND CUSTOMER_ID = :customerId AND CURRENT_USER_ID = 'UNASSIGNED'",
            "AND ACTIVE_IND = 'Y' AND TASK_STATUS != 'CLOSED'");

    try {

        List<MapSqlParameterSource> batchArgs = new ArrayList<>();

        for (Entry<String, List<Integer>> entry : resultMap.entrySet()) {
            MapSqlParameterSource params = new MapSqlParameterSource();
            params.addValue("currentUserId", userId);
            params.addValue("initialUserId", userId);
            params.addValue("userReassignTime", ts);
            params.addValue("lastCentralQueueData", todaysDate);
            params.addValue("reassignCentralDate", todaysDate);
            params.addValue("orgGwCreateTime", ts);
            params.addValue("lastUpdtUser", userId);
            params.addValue("lastUpdtTime", ts);
            params.addValue("contractId", entry.getKey());
            params.addValue("taskIds", entry.getValue());
            params.addValue("customerId", customerId);

            batchArgs.add(params);
        }

        int[] retVal = namedParameterJdbcTemplate.batchUpdate(query,
                batchArgs.toArray(new MapSqlParameterSource[resultMap.size()]));

        return retVal.length;

    } catch (DataAccessException exp) {
        throw new CustomException(exp, "Exception occured!");
    }
}

我期望在使用namedParameterJdbcTemplate.batchUpdate(query..)时查询能够批量运行但这会导致类型转换错误。

我看到问题出在batchUpdate查询中的IN子句中。请检查以下链接。希望这可以帮助： https://github.com/spring-projects/spring-framework/issues/21935

在查询中使用子句
