Spring Integration - WS Outbound Gateway

1.通过MessageSender客户化http连接参数

  AbstractHttpWebServiceMessageSender有若干实现子类:

  - CommonsHttpMessageSender(deprecated)

  - HttpComponentsMessageSender

  - HttpUrlConnectionMessageSender

 

2.CommonsHttpMessageSender

2.1 CommonsHttpMessageSender 需要依赖于Apache httpclient包

<dependency>
  <groupId>commons-httpclient</groupId>
  <artifactId>commons-httpclient</artifactId>
  <version>{version}</version>
</dependency>

2.2 示例源于spring integration sample master

<chain input-channel="fahrenheitChannel" output-channel="celsiusChannel">
  <ws:header-enricher>
    <ws:soap-action value="http://www.w3schools.com/webservices/CelsiusToFahrenheit" />
  </ws:header-enricher>
  <ws:outbound-gateway uri="http://www.w3schools.com/webservices/tempconvert.asmx" message-sender="httpSender"/>
</chain>

<beans:bean id="httpSender" class="org.springframework.ws.transport.http.CommonsHttpMessageSender">
  <beans:constructor-arg name="httpClient">
    <beans:bean class="org.apache.commons.httpclient.HttpClient">
      <beans:property name="httpConnectionManager" ref="httpConnectionManager" />
    </beans:bean>
  </beans:constructor-arg>
</beans:bean>

<beans:bean id="httpConnectionManager" class="org.apache.commons.httpclient.MultiThreadedHttpConnectionManager">
  <beans:property name="params">
    <beans:bean class="org.apache.commons.httpclient.params.HttpConnectionManagerParams">
      <beans:property name="soTimeout" value="5000" />
      <!-- <beans:property name="maxTotalConnections" value="100" />
         <beans:property name="defaultMaxConnectionsPerHost" value="100" /> -->
    </beans:bean>
  </beans:property>
</beans:bean>

3. HttpComponentsMessageSender

3.1 HttpComponentsMessageSender 需要依赖于Apache http components包

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3.3</version>
</dependency>

3.2 配置相对容易

<ws:outbound-gateway uri="http://www.w3schools.com/webservices/tempconvert.asmx" message-sender="httpComponentsSender" />

<beans:bean id="httpComponentsSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender">
  <beans:property name="connectionTimeout" value="12" />
  <beans:property name="readTimeout" value="12" />
</beans:bean>

That's it!
