JFinal介绍以及包下载路径

http://www.jfinal.com/

这个包里自带了很多重要的包，比较方面，其中有我们这个最简单的项目用到的

freemarker-2.3.20.jar和jfinal-1.9-bin.jar两个jar包

先定义Controller

package com.liangbinny.jfinal.action;import com.jfinal.core.Controller;public class HelloController extends Controller {/** * 默认路径 */    public void index() {        render("/index.jsp");    }    /**     * 指定路径,route里的url+/hello     */    public void hello() {        renderText("Hello JFinal World......");    }}

再定义config

package com.liangbinny.jfinal.config;import com.jfinal.config.Constants;import com.jfinal.config.Handlers;import com.jfinal.config.Interceptors;import com.jfinal.config.JFinalConfig;import com.jfinal.config.Plugins;import com.jfinal.config.Routes;import com.liangbinny.jfinal.action.HelloController;public class DefaultConfig extends JFinalConfig {@Overridepublic void configConstant(Constants me) {me.setDevMode(true);  }@Overridepublic void configHandler(Handlers arg0) {// TODO Auto-generated method stub}@Overridepublic void configInterceptor(Interceptors arg0) {// TODO Auto-generated method stub}@Overridepublic void configPlugin(Plugins arg0) {// TODO Auto-generated method stub}@Overridepublic void configRoute(Routes me) { me.add("/sayHello", HelloController.class);  }}

配置web.xml

<?xml version="1.0" encoding="ISO-8859-1"?><web-app xmlns="http://java.sun.com/xml/ns/javaee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee          http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"         version="3.0">    <filter>         <filter-name>jfinal</filter-name>         <filter-class>com.jfinal.core.JFinalFilter</filter-class>         <init-param>             <param-name>configClass</param-name>             <param-value>com.liangbinny.jfinal.config.DefaultConfig</param-value>         </init-param>     </filter>     <filter-mapping>         <filter-name>jfinal</filter-name>         <url-pattern>/*</url-pattern>     </filter-mapping></web-app>

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"    pageEncoding="windows-31j"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>hello</title></head><body><h1>hello Jfinal world</h1></body></html>

整个项目路径：

启动jetty，，访问项目路径

http://localhost:8080/JFinalTest/sayHello/

这个默认是直接进入index()方法，访问index.jsp

而访问http://localhost:8080/JFinalTest/sayHello/hello则调用controller里的hello方法，返回text
