resteasy 是 jboss的一个开源restful service实现参考。

# 项目结构： #

![这里写图片描述][SouthEast]  
本实例开发环境：intelliJ idea、jdk1.7 ,tomcat7

# 项目构建步骤 #

## 1、新建maven项目RestfulDemo ##

## 2、pom.xml ##

<?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
        <modelVersion>4.0.0</modelVersion>
    
        <groupId>RestfulDemo</groupId>
        <artifactId>RestfulDemo</artifactId>
        <version>1.0-SNAPSHOT</version>
        <packaging>war</packaging>
    
    
        <dependencies>
            
            <dependency>
                <groupId>org.jboss.resteasy</groupId>
                <artifactId>resteasy-jaxrs</artifactId>
                <version>2.2.1.GA</version>
            </dependency>
    
            
            
            <dependency>
                <groupId>org.jboss.resteasy</groupId>
                <artifactId>resteasy-spring</artifactId>
                <version>2.2.1.GA</version>
            </dependency>
    
            
            <dependency>
                <groupId>org.jboss.resteasy</groupId>
                <artifactId>resteasy-jaxb-provider</artifactId>
                <version>2.2.1.GA</version>
            </dependency>
    
            
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring</artifactId>
                <version>2.5.6.SEC03</version>
            </dependency>
        </dependencies>
    
    
    </project>

## 3、web.xml ##

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >
    
    <web-app>
        <display-name>Archetype Created Web Application</display-name>
        <context-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:spring/ApplicationContext.xml</param-value>
        </context-param>
        
        <listener>
            <listener-class>org.jboss.resteasy.plugins.server.servlet.ResteasyBootstrap</listener-class>
        </listener>
    
        <listener>
            <listener-class>org.jboss.resteasy.plugins.spring.SpringContextLoaderListener</listener-class>
        </listener>
        <servlet>
            <servlet-name>Resteasy</servlet-name>
            <servlet-class>org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher</servlet-class>
        </servlet>
    
        <servlet-mapping>
            <servlet-name>Resteasy</servlet-name>
            <url-pattern>/*</url-pattern>
        </servlet-mapping>
    
    </web-app>

## 4、ApplicationContext.xml ##

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd ">
        
        <bean id="testServicePoint" class="com.rest.demo.manager.point.TestServicePoint">
            <property name="manager" ref="manager" />
        </bean>
        
        <bean id="manager" class="com.rest.demo.manager.impl.ManagerImpl"/>
    </beans>

## 5、Manager接口 ##

package com.rest.demo.manager;
    
    /** * @author someone * @create 2017-10-09 15:28 **/
    public interface Manager { 
        public String getMessage(String message);
    }

## 6、ManagerImpl类 ##

package com.rest.demo.manager.impl;
    
    import com.rest.demo.manager.Manager;
    
    /** * @author someone * @create 2017-10-09 15:29 **/
    public class ManagerImpl implements Manager { 
        public String getMessage(String message) {
            return message;
        }
    }

## 7、TestServicePoint测试类 ##

package com.rest.demo.manager.point;
    
    import com.rest.demo.manager.Manager;
    
    import javax.ws.rs.GET;
    import javax.ws.rs.Path;
    import javax.ws.rs.PathParam;
    
    /** * @author someone * @create 2017-10-09 15:32 **/
    @Path(value = "/")
    public class TestServicePoint { 
        Manager manager;
    
        @GET
        @Path(value = "/echo/{message}")
        public String getMessage(@PathParam(value = "message") String message)
        {
            return manager.getMessage(message);
        }
    
        public Manager getManager() {
            return manager;
        }
        public void setManager(Manager manager) {
            this.manager = manager;
        }
    }

到这里，项目就已经写完啦！

# 项目部署： #

1、将项目部署到tomcat  
2、启动tomcat  
3、访问rest接口  
如：[http://localhost:8188/rest/echo/][http_localhost_8188_rest_echo]**hello**  
返回：**hello**  
如：[http://localhost:8188/rest/echo/][http_localhost_8188_rest_echo]**123**  
返回：**123**
