我必须按以下方式工作，
该类应扩展 AbstractMediator 并覆盖 mediate() 方法，如下所示，
package com.test.spring.mediator.workingexampleonspringmediator;
import org.apache.synapse.MessageContext;
import org.apache.synapse.mediators.AbstractMediator;
public class HelloWorld extends AbstractMediator{
private String message;
public void setMessage(String message){
this.message = message;
}
public boolean mediate(MessageContext arg0) {
System.out.println("HELLO "+message);
return true;
}
}
然后将jar放到[ESBHOME]/repository/components/lib文件夹中
在中介方法中，它会打印一条带有 HELLO 'arg' 之类参数的消息
我将以下文件添加到注册表(/_system/config/repository/spring/springtest.xml)，
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
<bean id="springtest" class="com.test.spring.mediator.workingexampleonspringmediator.HelloWorld" singleton="false">
<property name="message"><value>ISURU</value></property>
</bean>
</beans>
我的代理如下，
<proxy xmlns="http://ws.apache.org/ns/synapse" name="testSpring" transports="https,http" statistics="disable" trace="disable" startOnLoad="true">
<target>
<inSequence>
<log level="full">
<property name="START" value="__________________________"/>
</log>
<spring:spring xmlns:spring="http://ws.apache.org/ns/synapse" bean="springtest" key="conf:/repository/spring/springtest.xml"/>
<log level="full">
<property name="END" value="______________________"/>
</log>
</inSequence>
</target>
<description></description>
</proxy>
在代理中你可以看到bean=[bean id of the springtest.xml]和class=qualified name of the class
在我的 ESB 终端中，我使用 springtest.xml 中的给定属性值输出了以下内容，
[2013-11-07 17:38:30,654] INFO - LogMediator To: /services/testSpring.testSpringHttpSoap12Endpoint, WSAction: urn:mediate, SOAPAction: urn:mediate, MessageID: urn:uuid:bcae82e9-4027-43c5-bd7a-cbfa885aaf33, Direction: request, START = __________________________, Envelope: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"><soapenv:Body/></soapenv:Envelope>
HELLO ISURU

您必须在将 jar 放入 repository/components/lib 后重新启动 ESB
