JFinal项目搭建

1、Myeclipse中新建 Dynamic Web Project

导入jar包

2、配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

  <display-name>JFinalDemo</display-name>

  <filter>

    <filter-name>jfinal</filter-name>

    <filter-class>com.jfinal.core.JFinalFilter</filter-class>

    <init-param>

        <param-name>configClass</param-name>

        <param-value>com.demo.common.CommonConfig</param-value>

    </init-param>

  </filter>

  <filter-mapping>

    <filter-name>jfinal</filter-name>

    <url-pattern>/*</url-pattern>

  </filter-mapping>

  <welcome-file-list>

     <welcome-file>index.jsp</welcome-file>

  </welcome-file-list>

</web-app>

3、配置文件config.properties

jdbcUrl = jdbc:mysql://localhost:3306/jfinal?useUnicode=true&characterEncoding=utf-8

user = root

password =

devMode =true

4、配置jfinal启动文件

package com.demo.common;

import com.demo.common.controller.BlogController;

public class CommonConfig extends JFinalConfig {

	@Override

	public void configConstant(Constants me) {

		loadPropertyFile("config.properties");

		me.setDevMode(getPropertyToBoolean("devMode",false));

		me.setViewType(ViewType.JSP);

		me.setBaseViewPath("/WEB-INF/view");

	}

	@Override

	public void configRoute(Routes me) {

		me.add("/blog", BlogController.class);

		me.add("/hello", HelloController.class);

	}

	@Override

	public void configPlugin(Plugins me) {

		C3p0Plugin c3p0Plugin = new C3p0Plugin(getProperty("jdbcUrl"), getProperty("user"), getProperty("password"));

		me.add(c3p0Plugin);

		ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0Plugin);

		me.add(arp);

		arp.addMapping("blog",Blog.class);

	}

	@Override

	public void configInterceptor(Interceptors me) {

		// TODO Auto-generated method stub

	}

	@Override

	public void configHandler(Handlers me) {

		// TODO Auto-generated method stub

	}

	/**

	 * @param args

	 */

	public static void main(String[] args) {

		// TODO Auto-generated method stub

		JFinal.start("WebRoot", 81, "/", 5);

	}

}

5、控制器

package com.demo.common.controller;

import java.util.Date;

public class BlogController extends Controller {

	public void index(){

		setAttr("blogs", Blog.me.find("select * from blog"));

		render("index.jsp");

	}

	public void add(){

		String dosubmit = getPara("dosbumit");

		if(dosubmit==null || dosubmit.length()<=0){

			render("add.jsp");

		}else{

			Blog blog = getModel(Blog.class,"blog");

			blog.set("time", new Date());

			blog.save();

			index();

		}

	}

	public void del(){

		Integer id = getParaToInt(0);

		if(id==null || id<=0){

			renderText("数据异常");

			return;

		}

		Boolean flag = Blog.me.deleteById(id);

		if(!flag){

			renderText("数据已删除");

			return;

		}

		index();

	}

	public void update(){

		String dosubmit = getPara("dosbumit");

		if(dosubmit==null || dosubmit.length()<=0){

			Integer id = getParaToInt(0);

			if(id==null || id<=0){

				renderText("数据异常");

				return;

			}

			setAttr("blog", Blog.me.findById(id));

			render("update.jsp");

		}else{

			Blog blog = getModel(Blog.class,"blog");

			blog.update();

			index();

		}

	}

}

6、模型

package com.demo.common.model;

import com.jfinal.plugin.activerecord.Model;

public class Blog extends Model<Blog> {

	public final static Blog me = new Blog();

}

7、视图

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

  <head>
