Mule学习之路_1.MuleClient调用Mule发布的服务

据了解Mule通过Flow发布的服务默认就是通过CXF发布的，首先创建服务和实现类

Service:HelloWorld

package com.easyway.esb.mule;

import javax.jws.WebService;

@WebService
public interface HelloWorld
{
    String sayHi(String text);
}

实现类：HelloWorldImpl

package com.easyway.esb.mule;

import javax.jws.WebService;

@WebService(endpointInterface = "com.easyway.esb.mule.HelloWorld",serviceName = "HelloWorld")
public class HelloWorldImpl implements HelloWorld
{

    public String sayHi(String text)
    {
        return "Hello," + text;
    }
}

Flow文件 --JAXWS.xml

客户端代码

import org.mule.api.FutureMessageResult;
import org.mule.api.MuleContext;
import org.mule.api.MuleException;
import org.mule.api.MuleMessage;
import org.mule.api.config.ConfigurationBuilder;
import org.mule.api.config.ConfigurationException;
import org.mule.api.context.MuleContextBuilder;
import org.mule.api.context.MuleContextFactory;
import org.mule.config.spring.SpringXmlConfigurationBuilder;
import org.mule.context.DefaultMuleContextBuilder;
import org.mule.context.DefaultMuleContextFactory;
import org.mule.module.client.MuleClient;

public class MuleClientMain {
    public static void main(String[] args) throws Exception{  


     // Create a MuleContextFactory
      MuleContextFactory muleContextFactory = new DefaultMuleContextFactory();
       
      //create the configuration builder and optionally pass in one or more of these
      ConfigurationBuilder builder = 
          new SpringXmlConfigurationBuilder("JAXWS.xml");
      //The actual context builder to use
      MuleContextBuilder contextBuilder = new DefaultMuleContextBuilder();
       
      //Create the context
      MuleContext context = muleContextFactory.createMuleContext(builder,contextBuilder);
       
      //Start the context
      context.start();
       

      MuleClient client = new MuleClient(context);

      
      String url = "cxf:http://localhost:9090/hello?method=sayHi";
      MuleMessage message = client.send(url,"eagle",null);  
      String s = message.getPayloadAsstring();
      System.out.println(s);
      

      
    }  
        
}  

启动项目ruan as Mule Application

可以通过http://localhost:9090/hello可以看到SOAP信息

在输入方法名，参数，就可以得到返回值

http://localhost:9090/hello/sayHi/arg0/WuDi --syaHi为方法名，arg0为第一个参数，因为这个方法只有一个参数

如果有多个参数可以通过这个方式传 sayHi/arg0/bbb/arg1/aaa/arg3/...

WuDi为实参, 得到

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns2:sayHiResponse xmlns:ns2="http://mule.esb.easyway.com/">
<return>Hello,WuDi</return>
</ns2:sayHiResponse>
</soap:Body>
</soap:Envelope>

到此，实现了HelloWorld例子
