入力として配列を取るいくつかのメソッドを公開する Web サービスがあります。mule-config.xml ファイルで必要なフローをサービス実装に定義し、サービスによって公開された WSDL から WCF クライアントを作成できます。

クライアントからの入力として配列を受け入れるこれらのメソッドのいずれかを呼び出そうとすると、次の例外が発生します。

さらに調査したところ、array-entry-point-resolver が見つかりました。これを次のように私の mule-config に追加します

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

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

それでも役に立ちません。これについての経験はありますか？

この問題を解決するために、配列エントリポイントリゾルバー、メソッドエントリポイントリゾルバー、および API 署名の変更を組み合わせて使用​​することになりました。ここでの問題は、メソッド名の代わりに使用するメソッドを決定するために Mule が Web サービス呼び出しの引数を使用することです。ドキュメントには、メソッド エントリ ポイント リゾルバーを含む一連のリゾルバーを使用すると記載されていますが。

したがって、2 つの異なる名前のメソッドを公開するインターフェイスがあり、どちらも型 T の単一の配列を受け入れる場合、正しいメソッドが呼び出されることを保証するリゾルバーの組み合わせはありません。私が知る限りではありません。次のように、method-entry-point-resolver コレクションでこれらのメソッドを両方とも指定すると、次のようになります。

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

Mule は、入力引数が T[] の場合、メソッド名を無視して常に method1 を呼び出します。

これを試してみると：

<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 は常に正しいメソッドを呼び出すわけではありません。そこで、単純に T[] をラップするクラスを作成し、これを method1 への入力引数として変更しました。method-entry-point-resolvers のコレクションで method1 を構成し、array-entry-point-resolvers のコレクションで method2 を構成すると、これが機能します。

これは明らかに問題ですが、MuleSoft の担当者に対応してもらうことができませんでした。
