This article mainly introduces how to configure JFinal, which is very detailed and has a certain reference value. Friends who are interested must finish it!

Environment description:

Program version

JRE1.8

Tomcat7.0

Maven3.1.1

Intellij IDEA14.0.3

First, create a new Project

★ opens IDEA,Create New Project

★ builds Project through Maven, but does not use templates

Fill in the relevant names of Project in ★ and complete the creation of Project. Here the Project is named "jfinal-demo"

Second, change the current Project into a POM project.

As the parent project of the project, the project is used to define the version and coding mode of the packages that each module depends on.

★ deletes the src directory

★ edits the pom.xml under the root directory and sets the packaging format to pom.

Pom.xml of ★ parent project

Advertising is the driving force of persistence, click on advertising, is the greatest support for me!

3. New Module (module) "jfinal-web"

★ right-click the jfinal-demo directory to create a new child Module

Choose to use a template when creating a ★

After the ★ is created, the directory results are shown below

Fourth, write code for testing

★ create a new java directory under the main directory of the jfinal-web module

★ marks the newly created java directory as Sources Root, so that IDEA will treat the .java files in that directory as java source files

★ adds dependencies to the "jfinal-web" module. The version is already defined in the parent project, so you don't need to fill in version here.

Pom.xml of the ★ "jfinal-web" module

Jfinal-parentjfinal-demo1.0-SNAPSHOT4.0.0jfinal-webwarjfinal-web Maven Webapp http://maven.apache.orgjunitjunittestcom.jfinaljfinaljfinal-web

★ creates the Controller class "HelloController.java" for testing

The ★ class inherits the com.jfinal.core.Controller class and implements the index method

★ com.demo.controller.HelloController

Packagecom.demo.controller;importcom.jfinal.core.Controller;publicclassHelloControllerextendsController {publicvoidindex () {renderText ("hello world!");}}

★ creates the Config class "DemoConfig.java" for testing

The ★ class inherits the com.jfinal.config.JFinalConfi class and overrides five methods. Press the Alt+Insert shortcut key to generate code quickly

★ notice that the route "/ hello" is added here to define which controller is called when accessing the http://localhost/hello.

★ com.demo.config.DemoConfig

Packagecom.demo.config;importcom.demo.controller.HelloController;importcom.jfinal.config.*;publicclassDemoConfigextendsJFinalConfig {@ OverridepublicvoidconfigConstant (Constants me) {me.setDevMode (true);} @ OverridepublicvoidconfigRoute (Routes me) {me.add ("/ hello", HelloController.class);} @ OverridepublicvoidconfigPlugin (Plugins me) {} @ OverridepublicvoidconfigInterceptor (Interceptors me) {} @ OverridepublicvoidconfigHandler (Handlers me) {}

5. Configure the running environment

★ operates according to the picture, regardless of why.

Configure the filter of web.xml to ensure that all access can be blocked by JFinal

★ web.xml

"- / Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

"http://java.sun.com/dtd/web-app_2_3.dtd" > jfinal-demojfinalcom.jfinal.core.JFinalFilterconfigClasscom.demo.config.DemoConfigjfinal/*

7. Start the application

★ startup completed

★, open a browser to test it.
