一、所需的jar包（http://download.csdn.net/detail/huangzebiao007/6379995）
二、Hessian实现步骤
1、创建一个普通的web项目，并导入jar包
2、创建服务器端接口和实现类
package com.hzb;
public interface Hello {
public String sayHello(String name);
}
package com.hzb;
public class HelloImp implements Hello {
public String sayHello(String name) {
return name+":"+"hello world!";
}
}
3、在web.xml文件中配置hessian，并将该项目部署到tomcat上
<servlet>
<servlet-name>hello</servlet-name>
<servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class>
<init-param>
<param-name>home-class</param-name>
<param-value>com.hzb.HelloImp</param-value>
</init-param>
<init-param>
<param-name>home-api</param-name>
<param-value>com.hzb.Hello</param-value>
</init-param>
</servlet>
<!--下面是配置该接口对外提供的地址-->
<servlet-mapping>
<servlet-name>hello</servlet-name>
<url-pattern>/hello</url-pattern>
</servlet-mapping>
4、创建客户端项目（引入服务器项目或服务器端jar包）
package com.hzb.client;
import com.caucho.hessian.client.HessianProxyFactory;
import com.hzb.Hello;
public class HelloServiceTest {
public static void main(String[] args) throws Exception {
String url = "http://localhost:8080/Hessian/hello";
HessianProxyFactory factory = new HessianProxyFactory();
Hello hello = (Hello) factory.create(Hello.class, url);
System.out.println("远程调用结果: "+ hello.sayHello("hzb"));
}
}
运行结果：
远程调用结果: hzb:hello world!
