Mule ESB 的 DataMapper 自定义脚本？
Mule ESB's DataMapper custom script?
我正在尝试使用数据映射器。我正在尝试根据自己的喜好修改脚本，但即使在图形可视化中它似乎可以正常工作，我仍然会收到错误消息我可以看到字符串分开了。
这是我的脚本
String streetnumaddress = input.streetAddress;
String[] parts = streetnumaddress.split(",");
String streetnumber = parts[0];
String streetaddress = parts[1];
output.blabla= "Hello";
output.telephone = input.telephoneNumber;
output.lastname= input.sn;
output.firstname= input.givenName;
output.email = input.mail;
output.city= input.l;
output.province = input.st;
output.codepostal = input.postalCode;
output.country= "CA";
output.telephoneinternet = input.telephoneNumber;
output.immeubleetsuffixe = streetnumber;
output.odonyme = streetaddress;
基本上问题是分裂。当我像 output.blabla= "Hello" 这样直接影响字符串时；这行得通。但是分裂和做作是行不通的。知道如何解决这个问题吗？一开始是否有可能解决这个问题？
这是我的错误。

可以拆分字符串并将值分配给数据映射器中的输出值，就像您尝试做的那样。
您收到空指针异常，这意味着您的 "input.streetAddress" 可能为空。
你能检查一下你输入的街道地址数据是否存在。
