Question

我正在使用

SimpleWebServiceOutboundGateway 
    simpleGateway.setSendTimeout(1000);

调用Web服务，但有时Web服务需要更多时间来响应，我想设置超时，以便在响应延迟时终止流程。在setSendTimeOut之后，它会一直等待。我怎么能实现超时？

引用JavaDocs：

/**
 * Set the timeout for sending reply Messages.
 * @param sendTimeout The send timeout.
 */
public void setSendTimeout(long sendTimeout) {
    this.messagingTemplate.setSendTimeout(sendTimeout);
}

作为AbstractMessageProducingHandler的一部分，它与已经发送到输出通道的消息完全相关。这不是SOAP协议交互的一部分。

您必须查看特定WebServiceMessageSender的选项。例如，HttpComponentsMessageSender具有以下选项：

/**
 * Sets the timeout until a connection is established. A value of 0 means <em>never</em> timeout.
 *
 * @param timeout the timeout value in milliseconds
 * @see org.apache.http.params.HttpConnectionParams#setConnectionTimeout(org.apache.http.params.HttpParams, int)
 */
public void setConnectionTimeout(int timeout) {
    if (timeout < 0) {
        throw new IllegalArgumentException("timeout must be a non-negative value");
    }
    org.apache.http.params.HttpConnectionParams.setConnectionTimeout(getHttpClient().getParams(), timeout);
}

/**
 * Set the socket read timeout for the underlying HttpClient. A value of 0 means <em>never</em> timeout.
 *
 * @param timeout the timeout value in milliseconds
 * @see org.apache.http.params.HttpConnectionParams#setSoTimeout(org.apache.http.params.HttpParams, int)
 */
public void setReadTimeout(int timeout) {

使用配置文件

<int-http:inbound-gateway request-channel="requestData"  **reply-timeout="5000"**
        supported-methods="GET" path="/{oft}/users/{userId}"
        payload-expression="#pathVariables.userId"  reply-channel="responseChannel" >
         <int-http:header name="outputfile" expression="#pathVariables.oft"/>
    </int-http:inbound-gateway>

如何在Web服务调用中设置超时？
