Hessian 远程调用框架

Hessian(http://hessian.caucho.com)是一种轻量级的Web Service， 采用的是二进制的RPC协议。

 

 

Hessian可以形容是一种基于二进制协议提供RMI功能的组件。

1. 接口类IAnimalService.java

public interface IAnimalService {
    public String getMonkeyName();
}

 

  2  实现类AnimalServiceImp.java

public class AnimalServiceImp implements IAnimalService {
    @Override
    public String getMonkeyName() {
        return "I'm Jacky";
    }
}

 3web.xml配置

 

<servlet>
    <servlet-name>AnimalService</servlet-name>
    <servlet-class>com.caucho.hessian.server.HessianServlet</servlet-class>
    <init-param>
        <param-name>home-class</param-name>
        <param-value>com.demo.AnimalServiceImp</param-value>
    </init-param>
    <init-param>
        <param-name>home-api</param-name>
        <param-value>com.demo.IAnimalService</param-value>
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>AnimalService</servlet-name>
    <url-pattern>/service/animalService</url-pattern>
</servlet-mapping>
</servlet>

 

4客户端调用代码

final String url = "http://localhost:8080/service/animalService";
HessianProxyFactory factory = new HessianProxyFactory();
IAnimalService proxy = (IAnimalService) factory.create(IAnimalService.class, url);
System.out.println(proxy.getMonkeyName());
