手写tomcat

作为后端开发者，我们的通信都是基于socket服务器，但是因为各种服务容器的流行，类似tomcat、jboss之类的socket服务器帮我们实现了这部分功能，这让我们理所当然了，甚至有些小伙伴对这类工具到底是什么都不甚清楚。

使用netty实现，时间精力有限，功能较为简陋，旨在加深对socket服务器的理解

测试 servlet实现

package org.kwin.test.servlet;

import org.kwin.tomcat.annotation.WebServlet;
import org.kwin.tomcat.servlet.http.HttpServlet;
import org.kwin.tomcat.servlet.http.HttpServletRequest;
import org.kwin.tomcat.servlet.http.HttpServletResponse;


@WebServlet(urlPatterns = {"/a/*", "/b/*"})
public class DispatcherServlet extends HttpServlet {
    @Override
    public void doGet(HttpServletRequest req, HttpServletResponse resp) throws Exception {
        doPost(req, resp);
    }
    
    @Override
    public void doPost(HttpServletRequest req, HttpServletResponse resp) throws Exception {
        System.out.println("params :" + req.getParameters().toString());
        resp.setContentType("application/json");
        resp.getWriter().write("{"success":true,"code":"0","msg":null,"data":"heheheh"}");
    }
}

结果

 不多说了，show coding
