我有一个 web 服务，它公开了几种将数组作为输入的方法。我已经在 mule-config.xml 文件中为我的服务实现定义了一个流，并且可以从服务公开的 WSDL 创建我的 WCF 客户端。

如果我尝试调用这些方法之一，这些方法接受一个数组作为我的客户端的输入，我会收到以下异常：

经过进一步调查，我找到了数组入口点解析器。将其添加到我的 mule-config 如下

  <component>
           <entry-point-resolver-set>
                <reflection-entry-point-resolver/>
                <array-entry-point-resolver />
        </entry-point-resolver-set>

    <spring-object bean="myWebService"/>
</component>

仍然没有帮助。有这方面的经验吗？

我最终使用了数组入口点解析器、方法入口点解析器和 API 签名更改的组合来解决这个问题。这里的问题是，Mule 使用 web 服务调用的参数来确定要使用的方法而不是方法名称，即使它的文档说明它使用了一堆解析器，包括方法入口点解析器。

因此，如果您有一个接口公开了两个不同命名的方法，都接受一个类型为 T 的数组，那么解析器的组合将无法确保调用正确的方法。据我所知没有。如果您在 method-entry-point-resolver 集合中指定这两种方法，如下所示：

<method-entry-point-resolver>
                <include-entry-point method="method1"/>
                <include-entry-point method="method2"/> 
            </method-entry-point-resolver>

Mule 总是调用 method1，如果输入参数是 T[]，忽略方法名。

如果你试试这个：

<method-entry-point-resolver>
                <include-entry-point method="method1"/>                                         
            </method-entry-point-resolver>
            <array-entry-point-resolver>
               <include-entry-point method="method2"/>                 
            </array-entry-point-resolver>

Mule 始终没有调用正确的方法。所以我最终创建了一个简单地包装 T[] 并将其更改为方法 1 的输入参数的类。在方法入口点解析器的集合中配置了方法1，在数组入口点解析器的集合中配置了方法2，这可以工作。

这显然是一个问题，但我无法让 MuleSoft 人员做出回应。
