1、Myeclipse中 新建 Dynamic Web Project  

 

 

 

 

导入jar包

2、配置web.xml

       
         
      
       JFinalDemo
          
            
       
        jfinal
             
       
        com.jfinal.core.JFinalFilter
             
                 
        
         configClass
                  
        
         com.demo.common.CommonConfig
              
           
          
            
       
        jfinal
             
       
        /*
           
        
           
       
        index.jsp
         
      
     

3、配置文件config.properties

jdbcUrl = jdbc:mysql://localhost:3306/jfinal?useUnicode=true&characterEncoding=utf-8user = rootpassword =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
     
       {	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+"/";%>                  
       			
     	
     	
         	
     	
     	          
     		
     
     
	      
       添加博客
      
	      
		       
			        
ID
			        
标题
			        
内容
			        
时间
			        
操作
		       
	      
	      
		       
			        
${b.id }
			        
${b.title }
			        
${b.content }
			        
${b.time }
			        
			删除			|			编辑
