java.lang.NoSuchMethodError : org/apache/http/conn/scheme/Scheme. (Ljava/lang/String;ILorg/apache/http/conn/scheme/SchemeSocketFactory;)V

Question

我尝试使用 HttpComponentsMessageSender 在 Spring WebServiceTemplate 中设置 ConnectionTimeout 和 ReadTimeout。但是，我收到 SchemeSocketFactory 类的 NoSuchMethodError 错误。

<bean
    class="org.springframework.ws.transport.http.HttpComponentsMessageSender"
    id="timeoutId">
    <property name="connectionTimeout" value="3000" />
    <property name="readTimeout" value="3000" />
</bean>

我认为修复包升级可以为您解决这个问题。 WebSphere 有一个 Apache HTTP 客户端的内部副本(由其 JAX-RS 实现使用)，在修复包 8.5.5.9 之前，该副本对于已安装的应用程序是可见的。如果您想在此之前在修复包上使用您自己的副本，则需要利用 PARENT_LAST 类加载器委托(delegate)或隔离的共享库，以确保类加载器加载您自己的 Apache HTTP 副本而不是 WebSphere 的副本。
