Use Leopard MVC to learn how to use Leopard MVC.

This guide will guide you through the configuration of Leopard MVC.

How to complete this guide

You can start from scratch and complete each step, or you can bypass the basic setup steps you are already familiar. Either way, you can finally get the code that can work.

1. Configure maven dependency

Add pom. xml in the web module

    <dependencies>        [...]        <dependency>            <groupId>io.leopard</groupId>            <artifactId>leopard-test</artifactId>            <version>0.0.1-SNAPSHOT</version>        </dependency>        <dependency>            <groupId>io.leopard</groupId>            <artifactId>leopard-jetty</artifactId>            <version>0.0.1-SNAPSHOT</version>        </dependency>        <dependency>            <groupId>io.leopard</groupId>            <artifactId>leopard-web</artifactId>            <version>0.0.1-SNAPSHOT</version>        </dependency>        [...]    </dependencies>    <repositories>        <repository>            <id>leopard-snapshots</id>            <name>Leopard Snapshots</name>            <url>http://leopard.io/nexus/content/repositories/snapshots/</url>        </repository>    </repositories>

2. Configure web. xml

<context-param>        <param-name>contextConfigLocation</param-name>        <param-value>            classpath:/leopard-web/applicationContext.xml        </param-value>    </context-param>    <context-param>        <param-name>contextClass</param-name>        <param-value>io.leopard.web.LeopardXmlWebApplicationContext</param-value>    </context-param>    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>    <servlet>        <servlet-name>web</servlet-name>        <servlet-class>io.leopard.web.mvc.LeopardDispatcherServlet</servlet-class>        <init-param>            <param-name>contextConfigLocation</param-name>            <param-value>/WEB-INF/web-servlet.xml</param-value>        </init-param>        <load-on-startup>1</load-on-startup>    </servlet>    <servlet-mapping>        <servlet-name>web</servlet-name>        <url-pattern>/</url-pattern>    </servlet-mapping>

3. Use special parameters on the Leopard page

Createsrc/main/java/io/leopard/site/web/controller/ParameterController.java

package io.leopard.site.web.controller;import io.leopard.web4j.view.JsonView;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;@Controllerpublic class ParameterController {@RequestMappingpublic JsonView userAgent(String userAgent) {return new JsonView("userAgent:" + userAgent);}@RequestMappingpublic JsonView sessUid(long sessUid) {return new JsonView("sessUid:" + sessUid);}}

4. Compile JettyTest

src/test/java/io/leopard/site/JettyTest.java

package io.leopard.site;import io.leopard.jetty.JettyServer;import org.junit.Ignore;@Ignorepublic class JettyTest {public static void main(String[] args) throws Exception {JettyServer.start();}}

5. Run

Opensrc/test/java/io/leopard/site/JettyTest.javaRight-click Run As> Java Application and start Jetty test.

6. access through a browser

Http: // localhost/parameter. do? Format = true

{  "status" : "200",  "message" : "",  "data" : "userAgent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/35.0.1916.153 Safari/537.36"}

Summary

Congratulations! You can use Leopard MVC in the old project configuration. Although the function is simple, you can expand your business system on this basis. Good luck.
