新建项目

新建web项目

添加maven特性

方便导入jar包，不用一个个导入了

配置pom.xml

<dependencies>

目录结构

添加文件DefaultConfig.java

用于在web.xml中配置

package config;

import Model.User;

import com.jfinal.config.*;

import com.jfinal.kit.PropKit;

import com.jfinal.log.Log4jLoggerFactory;

import com.jfinal.plugin.activerecord.ActiveRecordPlugin;

import com.jfinal.plugin.druid.DruidPlugin;

import com.jfinal.render.ViewType;

import controller.HelloController;

import controller.UserController;

/**

 * Created by DawnHeaven on 16-5-30.

 */

public class DefaultConfig extends JFinalConfig {

	//全局设定

    @Override

    public void configConstant(Constants constants) {

        constants.setLoggerFactory(new Log4jLoggerFactory());

        constants.setEncoding("UTF-8");//设置编码

        constants.setDevMode(true);

        constants.setViewType(ViewType.FREE_MARKER);//设置视图模板 默认为freemarker

        constants.setFreeMarkerViewExtension(".ftl");

    }

    @Override

    public void configRoute(Routes routes) {

		//匹配路径为 / 使用HelloController处理

        routes.add("/", HelloController.class);

		//匹配路径为 /user 使用UserController处理， 最后一个参数是，返回的视图从哪个路径下寻找

        routes.add("/user", UserController.class, "/WEB-INF/template");

    }

    @Override

    public void configPlugin(Plugins plugins) {

		//配置数据库连接

        PropKit.use("jdbc.properties");

        final String URL =PropKit.get("jdbcUrl");

        final String USERNAME = PropKit.get("user");

        final String PASSWORD =PropKit.get("password");

        DruidPlugin druidPlugin = new DruidPlugin(URL,USERNAME,PASSWORD);

        druidPlugin.setFilters("stat,wall");

        plugins.add(druidPlugin);

        //注册service

        ActiveRecordPlugin activeRecordPlugin = new ActiveRecordPlugin(druidPlugin);

        //添加Model类和数据库表的映射。user指的是表名，userid指的是主键

        activeRecordPlugin.addMapping("user","id", User.class);

        plugins.add(activeRecordPlugin);

    }

    @Override

    public void configInterceptor(Interceptors interceptors) {

    }

    @Override

    public void configHandler(Handlers handlers) {

        handlers.add(new ContextPathHandler());

    }

}

web.xml中添加 filter

<filter>

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

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

    <init-param>

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

        <param-value>config.DefaultConfig</param-value>

    </init-param>

</filter>

<filter-mapping>

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

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

</filter-mapping>

ContextPathHandler

package config;

import com.jfinal.handler.Handler;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

/**

 */

public class ContextPathHandler extends Handler {

    @Override

    public void handle(String s, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, boolean[] booleans) {

        httpServletRequest.setAttribute("CONTEXT_PATH",httpServletRequest.getContextPath());

        nextHandler.handle(s, httpServletRequest, httpServletResponse, booleans);

    }

}

HelloController

package controller;

/**

 */

public class HelloController extends Controller {

//    @ActionKey("index") ActionKey的优先级高，没有匹配index

    public void index(){

        render("/index.html");

    }

}

UserController

package controller;

import java.util.Map;

/**

 */

public class UserController extends Controller {

    private UserService userService = new UserService();

    public void index(){

        setAttr("user", "fanzhijie");

        renderFreeMarker("user.ftl");//返回ftl页面

    }

    public void login(){

        String username = getPara("name");

        String password = getPara("phone");

        boolean loginCheck = userService.login(username,password);

        renderJson(loginCheck);//返回Json

    }

            map.put("email", email);

            map.put("json", 1);

            renderJson(map);

        }

        else

            renderJson("error");

    }

}

User

package Model;

import com.jfinal.plugin.activerecord.Model;

/**

public class User extends Model<User> {

}

UserService

package Service;

        Integer result = Db.queryFirst(SQL, name);

在js引入时，总是引用不到，我还没搞清楚具体的导入方法，我只是发现，我现有的目录结构下可以使用

知道的，可以提点我一下，谢谢
