Mule ESB 的 DataMapper 自定义脚本？

Question

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，但我一直收到错误消息，即使在图形可视化中它似乎正在工作，我可以看到字符串被分隔。

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。当我直接影响一个字符串时，比如 output.blabla="Hello";这行得通。但分裂和做作是行不通的。知道如何解决它，是否有可能首先做到这一点？

这是我的错误。

Answer 1

可以像您尝试的那样拆分字符串并将值分配给数据映射器中的输出值。

您得到一个空指针异常，这意味着您的“input.streetAddress”可能为空。 请检查您输入的街道地址数据是否存在。

Answer 2

我将其更改为 Groovy 脚本：

String acronymeministere = "YOOOO;"
String pays = "CA;"
String finalString = ""

payload.each { p ->

    String telephoneinternet = ";";
    String telephone = ";";
    String telecopieur = ";"
    String nomdefamille = ";";
    String prenom = ";";
    String initale =";"
    String qualificateurdegen = ";"
    String email = ";";
    String immeubleetsuffixe = ";"
    String odonyme = ";"
    String ville = ";";
    String province = ";";
    String codepostal = ";";
    String casepostale = ";"
    String bureau = ";"
    String etage = ";"
    String localisation = ";"
    String edifice = ";"
    String autres =";"

    if(p.streetAddress != null){
        String streetnumaddress = p.streetAddress;
        String[] parts = streetnumaddress.split(",");
        immeubleetsuffixe = parts[0].trim() + immeubleetsuffixe
        odonyme = parts[1].trim() + odonyme
    }

    telephoneinternet = p.telephoneNumber.toString().trim() + telephoneinternet
    telephone = p.telephoneNumber.toString().trim() + telephone
    nomdefamille = p.sn.toString().trim() + nomdefamille
    prenom = p.givenName.toString().trim() + prenom
    email = p.mail.toString().trim()    + email
    ville = p.l.toString().trim() + ville
    province = p.st.toString().trim() + province
    codepostal = p.postalCode.toString().trim() + codepostal


    finalString += ('"' + acronymeministere+telephoneinternet+telephone+telecopieur+nomdefamille
        +prenom+initale+qualificateurdegen+email+immeubleetsuffixe
        +odonyme+ville+province+codepostal+casepostale+pays+bureau+
        etage+localisation+edifice+autres+ '"'+'\n')
}

return finalString
