WSO2 ESB:使用Salesforce Connector时出现意外的字符错误

Question

当尝试按照WSO2 指示更新salesforce记录时,我收到以下错误.

Saleforce适配器 - 将sObjects注入有效负载时出错:org.apache.axiom.om.OMException:com.ctc.wstx.exc.WstxUnexpectedCharException:prolog中出现意外字符"{"(代码123); 预期'<'

                <sobjects

        <outSequence>
            <send/>
        </outSequence>
    </target>
</proxy>

我使用的是WSO2 EI 6.1.0和salesforce connector 2.0.1.Salesforce ID TestId1与字段ValueToChange一样存在.我的SalesforceLoginInfo是正确的(我可以执行Salesforce查询,而不是更新).

试图解决这个问题我看到了这个非常相似的问题.但是我已根据解决方案将行添加到axis2.xml,重新启动,问题仍然存在.

<messageBuilder contentType="application/json" class="org.wso2.carbon.integrator.core.json.JsonStreamBuilder"/>
<messageBuilder contentType="text/javascript" class="org.wso2.carbon.integrator.core.json.JsonStreamBuilder"/>

<messageFormatter contentType="application/json" class="org.wso2.carbon.integrator.core.json.JsonStreamFormatter"/>
<messageFormatter contentType="text/javascript" class="org.wso2.carbon.integrator.core.json.JsonStreamFormatter"/>

有谁知道如何解决这个问题？我觉得我只是在关注一个教程(我的代码几乎完全是给定的wso2 salesforce示例)但问题还在继续.

更新:为了减少对SalesforceLoginInfo调用的混淆,我将其删除并将salesforce.init放入代码中.错误仍然是一样的.

我可以通过删除 init 操作来重现该错误。

[2017-08-12 09:39:17,315] ERROR - SetupUpdateSobjects Saleforce adaptor - error injecting sObjects to payload : org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character '{' (code 123) in prolog; expected '<'

请在更新方法的顶部添加初始化操作。

            <salesforce.init>
            <loginUrl>{$ctx:loginUrl}</loginUrl>
            <username>{$ctx:username}</username>
            <password>{$ctx:password}</password>
            <blocking>{$ctx:blocking}</blocking>
        </salesforce.init>
                <payloadFactory>
                    <format>
                        <sfdc:sObjects xmlns:sfdc="sfdc" type="Account">
                            <sfdc:sObject>
                                <sfdc:Id>$1</sfdc:Id>
                                <sfdc:Name>$2</sfdc:Name>
                            </sfdc:sObject>
                        </sfdc:sObjects>
                    </format>
                    <args>
                        <arg expression="get-property('id')"/>
                        <arg expression="get-property('newName')"/>
                    </args>
                </payloadFactory>
                <salesforce.update>
                    <allOrNone>{$ctx:allOrNone}</allOrNone>
                    <allowFieldTruncate>{$ctx:allowFieldTruncate}</allowFieldTruncate>
                    <sobjects xmlns:sfdc="sfdc">{//sfdc:sObjects}</sobjects>
                </salesforce.update>

或者您为 init 创建本地条目并在代理中调用它[1]。

                <payloadFactory>
                <format>
                    <sfdc:sObjects xmlns:sfdc="sfdc" type="Account">
                        <sfdc:sObject>
                            <sfdc:Id>$1</sfdc:Id>
                            <sfdc:Name>$2</sfdc:Name>
                        </sfdc:sObject>
                    </sfdc:sObjects>
                </format>
                <args>
                    <arg expression="get-property('id')"/>
                    <arg expression="get-property('newName')"/>
                </args>
            </payloadFactory>
            <salesforce.update configkey="sf_init">
                <allOrNone>{$ctx:allOrNone}</allOrNone>
                <allowFieldTruncate>{$ctx:allowFieldTruncate}</allowFieldTruncate>
                <sobjects xmlns:sfdc="sfdc">{//sfdc:sObjects}</sobjects>
            </salesforce.update>
