代码如下：
RomoteTest.java
package client;
import java.net.MalformedURLException;
import server.Hello;
import com.caucho.hessian.client.HessianProxyFactory;
public class RomoteTest {
public static void main(String[] args) {
String url = "http://localhost:8080/Hessian/hessianService";
HessianProxyFactory factory = new HessianProxyFactory();
try {
Hello hello = (Hello) factory.create(Hello.class, url);
System.out.println(hello.hello("kingtoon"));
} catch (MalformedURLException e) {
e.printStackTrace();
}
}
}
HelloImpl.java
package server.impl;
import server.Hello;
public class HelloImpl implements Hello {
public String hello(String name) {
return "hello, " + name + "! Welcome to use Hessian.";
}
}
Hello.java
package server;
public interface Hello {
String hello(String name);
}
