【叨、校长】创建基于RestEasy框架的Rest应用

本教程基于RestEasy官方示例！通俗易懂、老少皆宜、不论男女！---叨、校长

1、用MyEclipse创建一个Java Web项目！

2、导入RestEasy框架所需要的JAR包(点击下载)

3、配置web.xml文件

 

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<!-- 手动注册Rest接口 -->
	<context-param>
		<param-name>resteasy.resources</param-name>
		<param-value>com.daodao.rest.HelloWorld</param-value>
	</context-param>
	<context-param>
		<param-name>resteasy.servlet.mapping.prefix</param-name>
		<param-value>/rest</param-value>
	</context-param>

	<listener>
		<listener-class>
			org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
	</listener>

	<servlet>
		<servlet-name>resteasy-servlet</servlet-name>
		<servlet-class>
			org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
	</servlet>

	<servlet-mapping>
		<servlet-name>resteasy-servlet</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>

	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
</web-app>

 4、编写测试接口：

 

package com.daodao.rest;

import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("/HelloWorld")
public class HelloWorld {
	
	@GET
	@Path("/sayHello")
	public String sayHello(){
		return "Hello World";
	}
}

 5、部署项目，测试应用：

http://localhost:8080/MyRest/rest/HelloWorld/sayHello
