JFinal快速上手及注意事项

官方手册虽然写的很详细但是忽略的很多小的细节方面，不看源码，网络资料又少，很多新手找不到解决办法。所以养成出了问题，多看源码的习惯

• 相关代码
• `package demo;

import com.jfinal.core.Controller;

public class myControll extends Controller{

public void index() {

      this.renderText("hello jfinal");

关于

JFinal.start("WebContent", 80, "/",5);

官方文件写的是 Jfinal.start(“src/main/webapp”,80,”/”,5);

其实这个路径写了 “/”就代表采用相对路径 而 默认执行index（）方法 ，如果 全部写出来，即为 http://localhost/hello/index 其他方法修改 index为你想要的方法即可
