0 Basic Small white users can also read! Jfinal of the framework recommended for Java practitioners (with actual combat)

jfinal is based on Java the speed of language WEB + ORM Development Framework whose core design objective is to develop

Fast, less code, learning simple, powerful, lightweight, easy to expand, Restful . In the owning Java

with all the advantages of the language. Ruby , python , PHP the development efficiency of such dynamic language !

jfinal has the following main features:

L MVC Architecture, compact design, easy to use

L Follow COC principle, 0 configuration, none XML

L Original Db + Record mode, flexible and convenient

L ActiveRecord support, making database development extremely fast

L automatic loading of modified Java files that do not need to be restarted during development Web Server

L AOP support, the interceptor configuration is flexible and powerful

L Plugin architecture, Strong extensibility

L Multi-view support, support Freemarker , JSP , Velocity

L Powerful, Validator Back-end Check function

L fully functional, with struts2 Most core functions

L Small size only 303K , and no third-party dependencies

Next, you'll actually create a small project. First, create a Dynamic Web Project

Fill in the project basic information

Note:Target runtime must choose <None>

Modify the default Output Folder, recommended Input webroot\web-inf\classes

Note: The Default out folder here must be exactly the same as the webroot\web-inf\classes directory to

To start the project using jfinal integrated Jetty .

Modify content directory, recommended input WebRoot

Note: The default value webcontentcan also be used here, but the webroot\web-inf\classes in the previous step needs to be changed to webcontent\ Web-inf\classes to the corresponding.

Put Jfinal library file

Copy the Jfinal-xxx.jar and Jetty-server-8.1.8.jar to the project web-inf\lib Next.

Note:Jetty-server-8.1.8.jar is a running environment that is used at development time, and this file is not required for production environments.

Modify Web. xml

Add the following to the Web. XML

<filter>

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

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

<init-param>

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

<param-value>demo. Democonfig</param-value>

</init-param>

</filter>

<filter-mapping>

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

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

</filter-mapping>

adding Java files

Create the demo package under the project src directory and create the democonfig file under the demo package , The contents are as follows:

Package demo;

Import com.jfinal.config.*;

public class Democonfig extends Jfinalconfig {

public void Configconstant (Constants me) {

Me.setdevmode (TRUE);

}

public void Configroute (Routes me) {

Me.add ("/hello", Hellocontroller.class);

}

public void Configplugin (Plugins me) {}

public void Configinterceptor (interceptors me) {}

public void Confighandler (handlers me) {}

}

Note: The package that contains theDemoconfig.java file and its own file name must be the same as the param-value in Web . xml

The configuration in the check is consistent ( In this case, the configuration is demo.) Democonfig).

Under the demo package, create a Hellocontroller class file that reads as follows:

Package demo;

Import Com.jfinal.core.Controller;

public class Hellocontroller extends Controller {

public void index () {

RenderText ("Hello jfinal World");

}

}

Start Project

Create the startup entry as shown in:

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M01/7F/06/wKioL1cQfq6QLdDVAAA9lqWUDr0824.png "title=" Picture 5.png "alt=" Wkiol1cqfq6qlddvaaa9lqwudr0824.png "/>

Right-click on Java application and select new menu item to create The Java application startup item

In the right window, fill in the Main class input Box : Com.jfinal.core.JFinal and click Debug button Startup Item

As shown in the following items:

Open the browser to see the effect

Open the browser in the address bar input : Http://localhost/hello, the output is the Hello jfinal World Certification Project

The frame is built to completion.

The use of jfinal has been a period of time, deeply appreciate its convenience, and strongly share to everyone, specially organized a bit about the jfinal of information to share to everyone,/http/ www.36zhen.com/tid=207, if you have any questions, also welcome Dabigatran 413461338 together to discuss learning!
