一,简单rpc 是基于Java socket 编程

ServerSocket serverSocket =  new ServerSocket(9999);
   System.out.println("服务开启");
            while(true) {
                //开启一个服务监听 
                Socket socket = serverSocket.accept();
                System.out.println(socket.getInetAddress()+"-connected");
                InputStream in = socket.getInputStream();
                byte[] buf = new byte[1024];
                in.read(buf);
                
         //拿到序列化得数据
byte[] formatDate = formatData(buf); OutputStream out = socket.getOutputStream(); out.write(formatDate); socket.close();
}

通过NetModel类保证从客户端传入的参数 包括 类的名称  方法名称  参数类型 参数

package org.Simple.API;

import java.io.Serializable;
import java.util.Arrays;

public class NetModel implements Serializable{


	private static final long serialVersionUID = 1L;

	private String className;

	private String method;

	private  Object[] args ;

	private String[] types;

	public String getClassName() {
		return className;
	}

	public void setClassName(String className) {
		this.className = className;
	}

	public String getMethod() {
		return method;
	}

	public void setMethod(String method) {
		this.method = method;
	}

	public Object[] getArgs() {
		return args;
	}

	public void setArgs(Object[] args) {
		this.args = args;
	}


	public String[] getTypes() {
		return types;
	}

	public void setTypes(String[] types) {
		this.types = types;
	}

	@Override
	public String toString() {
		return "NetModel [className=" + className + ", method=" + method + ", args=" + Arrays.toString(args)
				+ ", types=" + Arrays.toString(types) + "]";
	}
}

  通过Java 反射 调用方法生成结果 在通过 serversocket 返回给客户端

try {
			 //将收到的byte数组反序列化为NetModel类型,然后通过反射调用HelloServiceImpl实现类的方法
            NetModel netModel = (NetModel)SerializeUtils.deSerialize(bs);
            //包点类名称
            String className = netModel.getClassName();
            //参数类型
            String[] types = netModel.getTypes();
            //参数
            Object[] args = netModel.getArgs();

            /*这里简单通过Map来做接口映射到实现类,从map中取
            Map<String, String> map = new HashMap<String,String>();
            map.put("org.Simple.API.HelloService", "org.Simple.S.HelloServiceImpl");
            Class<?> clazz = Class.forName(map.get(className));
            */
            //也可以把这个键值放到配置文件下,通过配置文件读取
            Class<?> clazz = Class.forName(getPropertyValue(className));
            Class<?> [] typeClazzs = null;
            if(types!=null) {
                typeClazzs = new Class[types.length];
                for (int i = 0; i < typeClazzs.length; i++) {
                    typeClazzs[i] = Class.forName(types[i]);
                }
            }

            Method method = clazz.getMethod(netModel.getMethod(),typeClazzs);

            //方法调用 参数
            Object object = method.invoke(clazz.newInstance(), args);

            byte[] byteArray = SerializeUtils.serialize(object);

            return byteArray;

		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
