Mule ESB 学习笔记（5）

5.3 同步方式

同步方式即请求方调用服务后，component将处理结果发送给另外一个外部服务处理，并将处理结果反方向返回。

同步方式经过inbound和outbound endpoint的exchange-pattern=”request-response”实现，相应配置以下：

<flow name="echo">  
    <inbound-endpoint address="http://localhost:7007/services/Echo"  
        exchange-pattern="request-response" />  
    <cxf:jaxws-service serviceClass="demo.mule.umo.Echo" />  
    <component>  
        <singleton-object class="demo.mule.umo.StdIo" />  
    </component>  
    <vm:outbound-endpoint path="vm" exchange-pattern="request-response" />  
</flow>  
<flow name="vm">  
    <vm:inbound-endpoint path="vm" exchange-pattern="request-response" />  
    <component>  
        <singleton-object class="demo.mule.umo.Vm" />  
    </component>  
    <stdio:outbound-endpoint system="OUT" exchange-pattern="one-way" />  
</flow>

同步方式适用于经过Mule调用远程服务的场景。
