异构语言交互访问 解决方案及例子（一）

异构语言交互访问 解决方案及例子（一）
方案一
后台 c++实现 、前端java调用
开源库：后端jsonrpc库 前端：jsonrpc4j
方案二
采用webservice实现
后台 c++实现 、前端java调用
开源库：后端：gsoap 前端：cxf

jsonrpc4j 库测试

---》服务端
import java.io.IOException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.googlecode.jsonrpc4j.JsonRpcServer;

public class HelloWorldServlet extends  HttpServlet {
    private static final long serialVersionUID = 3638336826344504848L;
    private JsonRpcServer rpcService = null;
    @Override
    public void init(ServletConfig config) throws ServletException {
        super.init(config);
        rpcService = new JsonRpcServer(new HelloWorldService(), HelloWorldService.class);
    }

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp)
            throws ServletException, IOException {
        rpcService.handle(req, resp);    
    }
}




public class HelloWorldService{
public String SayHello(){
String s =  "hello!";
System.out.println(s);
return s;
}
}


---》客户端

import java.net.URL;

import com.googlecode.jsonrpc4j.JsonRpcHttpClient;

public class JavaRpcTest {
/**
* @param args
* @throws Throwable
*/
public static void main(String[] args) throws Throwable {
JsonRpcHttpClient client = new JsonRpcHttpClient(new URL("http://127.0.0.1:8888/javaRpcTest/index.json"));
        String properties = client.invoke("SayHello", null, String.class);
        System.out.println(properties);
}
}
