Question

我在salesforce上练习mulesoft连接。我正在尝试从salesforce查询帐户，使用Invoke Component执行一些逻辑并更新Salesforce中的帐户名称。请在下面找到XML代码。我调用时出现以下错误..

表达式“变量：Fname = __ object_for_enrichment”的执行失败。（org.mule.api.expression.ExpressionRuntimeException）。

XML：

<http:listener-config name="HTTP_Listener_Configuration" host="localhost" port="8092" doc:name="HTTP Listener Configuration"/>
    <sfdc:config name="Salesforce__Basic_Authentication" username="username" password="*******" securityToken="Token" doc:name="Salesforce: Basic Authentication" url="https://login.salesforce.com/services/Soap/u/38.0">
        <reconnect-forever/>
    </sfdc:config>
    <spring:beans>
        <spring:bean id="Bean" name="UpdateAcc" class="com.pack.salesforceconnect.SFJava"/>
    </spring:beans>

    ShippingCity: payload.ShippingCity
}]]></dw:set-payload>
        </dw:transform-message>
        <enricher source="#[payload.Name]" target="#[Variable:Fname]" doc:name="Message Enricher">
            <invoke name="Invoke" object-ref="UpdateAcc" method="ChangeSCity" methodArguments="#[payload.Name]" metadata:id="id"/>
        </enricher>
        <dw:transform-message doc:name="Transform Message">

}]]]></dw:set-payload>
        </dw:transform-message>
        <set-payload value="#[payload]" doc:name="Set Payload"/>
    </flow>
</mule>

类别：

package com.pack.salesforceconnect;

public class SFJava {
    public String ChangeSCity(String Fname){
        //String ShippingCity;
        System.out.print("Account Name received : "+Fname);
        if (Fname == null){
         Fname = "New Account";
        }else{
            Fname = "Washington Industries Inc.,";
            }
        System.out.print("Account Name: "+Fname);

        return Fname;
        }

}

Answer 1

语法错误..它将是target="#[variable:Fname]"而不是target="#[Variable:Fname]"
或者只是您可以使用target="#[flowVars.Fname]"
