我正在尝试使用“PutSQL”处理器来做到这一点.
我修改流文件使用“ReplaceText”并创建一个INSERT语句.我已经在MySQL数据库中测试了该语句,并且该语句有效.
这是声明：
INSERT INTO monitor.security_nifi (RemoteIPAddress,Timestamp,RequestUrl,Status,Instance)
VALUES ('10.129.2.35','2016-09-2016:44:16,347','/secure/Dashboard.jspa','PASSED','35');
当它通过处理器时,我不断收到此错误：
failed to process session due to java.lang.IndexOutOfBoundsException:
Index:1,Size:1: java.lang.IndexOutOfBoundsException: Index:1,Size:1
这是堆栈跟踪：

最佳答案
这看起来像是隐藏实际问题的错误.尝试将PutSQL处理器的“支持分段事务”属性设置为“false”.这应该可以防止Index Out of Bounds Exception,但也可以揭示一个可以纠正的真正问题.如果这是真的(存在另一个问题并且已得到纠正),您可以将属性值恢复为“true”并运行而不会出现错误. （编辑：莱芜站长网）
