大家好,又见面了,我是你们的朋友全栈君。
最近研究rest接口,发现restlet应用挺广泛,不过入门资料很少,去官网下载jar包,根据官网说明搭建了一个简单的restlet工程:
1、首先导入jar包
2、编写业务逻辑类
package com.chen.rest;
import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;
/**
* @author chenjie
* @version 1.0
* @since 2017-02-08
*/
public class HelloWorld extends ServerResource
{
@Get
public String represent()
{
return "hello world!";
}
}
3、编写应用类
package com.chen.rest;
import org.restlet.Application;
import org.restlet.Restlet;
import org.restlet.routing.Router;
/**
* @author chenjie
* @version 1.0
* @since 2017-02-08
*/
public class FirstApp extends Application
{
@Override
public synchronized Restlet createInboundRoot()
{
System.out.println("1111111111");
Router router = new Router(getContext());
router.attach("/hello",HelloWorld.class);
return router;
}
}
4、配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>first steps servlet</display-name> <!-- Restlet adapter --> <servlet> <servlet-name>RestletServlet</servlet-name> <servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class> <init-param> <!-- Application class name --> <param-name>org.restlet.application</param-name> <param-value>com.chen.rest.FirstApp</param-value> </init-param> </servlet> <!-- Catch all requests --> <servlet-mapping> <servlet-name>RestletServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app>
5、部署工程到tomcat,启动tomcat,访问
http://localhost:8080/myRest/hello
