使用addBatch java时丢失数据

我使用executeBatch插入数据但是有些数据丢失了，在数据库中找不到，没有发现任何异常 .
DB：Oracle .
驱动程序版本：11.2.0.4.0
池：UCP：Oracle通用连接池
请帮忙 .

这是我的代码：

protected static void insertExtraData(String serviceCode, JsonObject extras, PaymentRequest request) {
    PreparedStatement ps = null;
    long tid = request.getTransId();
    long coreId = request.getCoreTransId();
    Connection con = null;
    try {
        con = ConnectionFactory.getConnection();
        con.setAutoCommit(false);
        ps = con.prepareStatement("INSERT INTO REPORT_ADMIN.SHOPPING_TRANS_DATA VALUES(?,?,?)");
        MultiLog.write(serviceCode, tid, coreId, "INSERT INTO REPORT_ADMIN.SHOPPING_TRANS_DATA VALUES(?,?,?)");
        Set<String> fieldNames = extras.getFieldNames();
        for (String fieldName : fieldNames) {
            MultiLog.write(serviceCode, tid, coreId, "para 01: " + tid);
            MultiLog.write(serviceCode, tid, coreId, "para 02: " + fieldName);
            MultiLog.write(serviceCode, tid, coreId, "para 03: " + extras.getString(fieldName));
            ps.setString(1, String.valueOf(tid));
            ps.setString(2, Utils.nullToEmpty(fieldName));
            ps.setString(3, Utils.nullToEmpty(extras.getString(fieldName)));
            MultiLog.write(serviceCode, tid, coreId, "add Batch");
            ps.addBatch();
        }
        ps.executeBatch();
        con.commit();
    }
    catch (Exception e) {
        MultiLog.error(serviceCode, tid, "ERROR", e);

    }
    finally {
        Utils.close(ps);
        Utils.close(con);
    }
}

这是我的日志：
