Talend tMap如果數學符號的條件爲字符串

Question

我在表中有一列，有些值有反斜槓/結束。我想刪除這些斜槓值並保留文本的其餘部分。所以可以說我有一個文本"myjunkdata/"，它應該讓我回到"myjunkdata"。但是，以下情況不起作用。下面

Certified SOA Security Specialist/ 
Information Security Management Principles Foundation Certificate/ 
Check Point Certified Security Administrator R77/ 
Check Point Certified Security Expert R77/

(StringHandling.RIGHT(row1.CertificateName,1) == "/") ? StringHandling.LEFT(row1.CertificateName,StringHandling.LEN(row1.CertificateName)-1) : row1.CertificateName 

例如數據誰能幫助？

Answer 1

不要比較String與==

StringHandling.RIGHT(row1.CertificateName,1).equals("/") 

但是你可以用做同樣的條件：

row1.CertificateName.endsWith("/") 

但當然，一個正則表達式總是這樣做只是

row1.CertificateName.replaceAll("/$") 

的解決方案

正則表達式/$基本上意味着結束w因爲/所以它會刪除該字符，如果它存在。
