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 {

	@RequestMapping
	public JsonView userAgent(String userAgent) {
		return new JsonView("userAgent:" + userAgent);
	}

	@RequestMapping
	public 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。
