水壶：计算色谱柱长度

Question

我跟随Kettle转型：

输出结果为：

2017/06/02 14:51:10 - Write to log.0 - ------------> Linenr 1------------------------------
2017/06/02 14:51:10 - Write to log.0 - Text = This is line 1
2017/06/02 14:51:10 - Write to log.0 - Length =  11
2017/06/02 14:51:10 - Write to log.0 - Copy = [B@709B5D90
2017/06/02 14:51:10 - Write to log.0 -

似乎壶通过其哈希码而不是其值来引用“文本”列。我做错了什么？

Answer 1

您看到的值不是哈希码，而是对原始数据的引用。当输入步骤启用延迟转换时会发生这种情况。计算器步骤应该触发转换为字符串，但出于某种原因，在这种情况下会跳过它。

取消选中CSV输入步骤中的延迟转换以修复它。
