我尝试使用批处理将数据库插入Oracle数据库。如果列数小于50，一切正常并且插入有效。但是如果列数为50或更多，我会收到错误（java.lang.ArrayIndexOutOfBoundsException）。
完整堆栈跟踪如下所示：

在上面的日志＆lt; 有效负载＆gt;中，＆lt; 插入查询＆gt;是我从原始有效负载和插入查询替换的占位符。 因为它是客户数据，所以我无法共享这些字段。但插入查询看起来像这样：
INSERT INTO Table123(col1,col,.....upto 50)VALUES(#[message.payload.'col1'],#[message.payload.'col2'],...upto #[message.payload.'col50'])
