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>
    <base href="<%=basePath%>">

  </head>
  
  <body>
    <table class="table table-striped table-bordered">
	<caption><a href="/blog/add" class="btn btn-primary">添加博客</a></caption>
	<thead>
		<tr>
			<th>ID</th>
			<th>标题</th>

	</thead>
	<tbody>
		<c:forEach items="${blogs }" var="b">
		<tr>

		</tr>
		</c:forEach>
	</tbody>
</table>
  </body>
</html>
