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;@Controller
public 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;@Ignore
public 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。
