使用Leopard MVC

学习如何在使用Leopard MVC。

本指南将引导您完成Leopard MVC的配置。

How to complete this guide

你可以从头开始并完成每一个步骤,或者您可以绕过你已经熟悉的基本设置步骤。无论哪种方式,你最终都可以得到可工作的代码。

1、配置maven依赖

在web模块的pom.xml加入

    <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、配置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、使用Leopard页面特殊参数

创建src/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、编写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、运行

打开src/test/java/io/leopard/site/JettyTest.java，右键菜单Run As -> Java Application启动Jetty测试

6、使用浏览器访问

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"}

总结

恭喜你！您已经可以在旧项目配置使用Leopard MVC，虽然功能比较简单，你可以在这个基础上扩展出你的业务系统，祝您好运。
