私は現在、レストサービスを構築するために resteasy をいじっていますが、デフォルトの connectionManager(SimpleHttpConnectionManager) では、長時間実行されるトランザクション メソッドで 1 つの接続しか維持できません。そこで、MultiThreadedHttpConnectionManager で Bean を初期化しようとしました
私のポン:
<properties>
<resteasy.version>2.1.0.GA</resteasy.version>
<spring.version>3.0.5.RELEASE</spring.version>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

私のapplicationContext.xml
<bean id="httpClient" class="org.apache.commons.httpclient.HttpClient">
<constructor-arg>
<bean class="org.apache.commons.httpclient.MultiThreadedHttpConnectionManager"
p:maxConnectionsPerHost="10"
p:maxTotalConnections="20"/>
</constructor-arg>
</bean>
<bean id="myRestService"
class="org.jboss.resteasy.client.spring.RestClientProxyFactoryBean"
p:serviceInterface="com.me.service.myRestService"
p:baseUri="${serviceNameUrl}"
p:httpClient-ref="restHttpClient"/>
しかし、jboss 6 サーバーを起動すると、次の例外が発生しました。

resteasy パッケージの依存バージョンを検索しようとしています。ただし、必要な commons-httpclient は同じです (バージョン 3.1)。では、「HttpClient」が「HttpClient」に変換できないのはなぜですか?
