Question

这是场景： - 三个序列：s1，s2，s3 - 存储在注册表（localEntry）中的一个变量设置为1 - 获取带有concat的seqName - 尝试使用get-property

调用序列

到目前为止我做了什么：

1）提取值

MyClass.prototype.foo = function(){
    var arr = [1, 2, 3];
    var myCurrentInstance = this;    //Store temporary reference
    arr.forEach(function(element){
        //Here it works because I use the temporary reference
        myCurrentInstance.elements.push(element);
    });
}

2）Concat

    <property name="getSequence" expression="get-property('registry','conf:repository/myVersion2.xml')" scope="default" type="OM"/>
<log level="custom">
    <property name="TestVersion::localEntry"    expression="$ctx:getSequence//localEntry"/>
</log>

3）调用序列

     <property name="seqName"
               expression="concat('s', $ctx:getSequence//localEntry)"
               scope="default"
               type="STRING"/>

4）执行测试

5）获取错误：

           <sequence key="get-property('seqName')"/>

所以问题似乎是“seqName”中存储的信息如何被序列读取为序列名而不是字符串。

我也试过

但这也行不通......

提前谢谢。

固定！

<sequence xmlns:local="ws.apache.org/ns/synapse" key="{get-property('seqName')}"/>

感谢大家！
