话不多说，先看具体的例子：

文件目录结构：

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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"
	version="2.5">
	<display-name>platform</display-name>
	<!-- Spring ApplicationContext配置文件的路径,可使用通配符,多个路径用,号分隔 此参数用于后面的Spring Context 
		Loader -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:/applicationContext.xml,classpath:/applicationContext-rs.xml
		</param-value>
	</context-param>

	<!-- Character Encoding filter -->
	<filter>
		<filter-name>encodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>

		</init-param>
	</filter>

	<filter-mapping>

		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<!-- Spring 刷新Introspector防止内存泄露 -->
	<listener>
		<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
	</listener>
	<!-- Apache CXF Servlet 配置 -->
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
	</servlet>
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/rest/*</url-pattern>
	</servlet-mapping>
</web-app>

Spring的xml—applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>

RestFul的xml— applicationContext-rs.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" xmlns:jaxrs="http://cxf.apache.org/jaxrs"

		</jaxrs:inInterceptors>
		<jaxrs:serviceBeans>
			<ref bean="userinfoServiceImpl" />

	</jaxrs:server>

</beans>

实体：

package com.zd.entity;
import java.io.Serializable;

/** 系统用户表 **/
public class UserInfo implements Serializable {
	
	private String id;
	private String name;// 用户姓名
	private String sex;// 性别
	private String idNo;//身份证号码
	private String account;// 账号
	private String pwd;// 密码

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getAccount() {
		return account;
	}

	public void setAccount(String account) {
		this.account = account;
	}

	public String getPwd() {
		return pwd;
	}

	public void setPwd(String pwd) {
		this.pwd = pwd;
	}

	public String getSex() {
		return sex;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}
	
	public String getIdNo() {
		return idNo;
	}

	public void setIdNo(String idNo) {
		this.idNo = idNo;
	}
}

构建的XML实体：

package com.zd.dtd;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;

@XmlRootElement(name="UserInfoDTO")
@XmlAccessorType(XmlAccessType.PROPERTY)
@XmlType
public class UserInfoDTD {
	private String id;
	private String name;// 用户姓名
	private String sex;// 性别
	private String idNo;//身份证号码
	private String account;// 账号
	private String pwd;// 密码
	@XmlElement(name="id",required=false)
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	@XmlElement(name="name",required=false)
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@XmlElement(name="account",required=false)
	public String getAccount() {
		return account;
	}
	public void setAccount(String account) {
		this.account = account;
	}
	@XmlElement(name="sex",required=false)
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	@XmlElement(name="sex",required=false)
	public String getIdNo() {
		return idNo;
	}
	public void setIdNo(String idNo) {
		this.idNo = idNo;
	}
	@XmlElement(name="sex",required=false)
	public String getPwd() {
		return pwd;
	}
	public void setPwd(String pwd) {
		this.pwd = pwd;
	}
}

接口服务层：

package com.zd.service;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

@Path("/Userinfo")
public interface UserinfoService {

	/**
	 * 根据id获取用户信息
	 * @param id 用户id
	 * @return json数据
	 */
	@GET
	@Path("/getUserinfo")
	@Produces({ "text/html;charset=utf-8", MediaType.TEXT_HTML })
	public Response getBasicUserInfo(@QueryParam("id") String id);
}

服务实现层：

package com.zd.serviceImpl;

import javax.ws.rs.core.Response; 

import net.sf.json.JSONArray;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.zd.beanImpl.UserBeanImpl;
import com.zd.dtd.UserInfoDTD;
import com.zd.entity.UserInfo;
import com.zd.service.UserinfoService;
 
@Component
public class UserinfoServiceImpl implements UserinfoService {

	@Autowired(required=true)
	private UserBeanImpl userBeanImpl;
	
	@Override
	public Response getBasicUserInfo(String id) {
		
		UserInfo userInfo = userBeanImpl.getUserInfo(id);
		
		UserInfoDTD userDTD=new UserInfoDTD();
		userDTD.setSex(userInfo.getSex());
		userDTD.setId(userInfo.getId());
		userDTD.setIdNo(userInfo.getIdNo());
		userDTD.setName(userInfo.getName());
		userDTD.setPwd(userInfo.getPwd());
		userDTD.setAccount(userInfo.getAccount());
		//json转换
		JSONArray jsonArray = JSONArray.fromObject(userInfo);
		return Response.ok(jsonArray.toString()).build();
	}
}

ServiceBean：

package com.zd.beanImpl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.zd.daoImpl.UserinfoDaoImpl;
import com.zd.entity.UserInfo;

@Service
//默认将类中的所有函数纳入事务管理.
@Transactional 
public class UserBeanImpl {
	@Autowired(required=true)
	private UserinfoDaoImpl userinfoDaoImpl;
	public UserInfo getUserInfo(String id){
		UserInfo userInfo=userinfoDaoImpl.getUserinfo(id);
		return userInfo;
		
	}
}

Dao：

package com.zd.daoImpl;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;

import com.zd.entity.UserInfo;
@Repository
//默认将类中的所有函数纳入事务管理.
@Transactional
public class UserinfoDaoImpl {
	public UserInfo getUserinfo(String id){
		UserInfo userInfo=new UserInfo();
		userInfo.setAccount("zhudan");
		userInfo.setId("1111");
		userInfo.setId("520911188119186770");
		userInfo.setName("朱丹");
		userInfo.setPwd("1221");
		userInfo.setSex("女");
		return userInfo;
	}
}
