Java 两种方式实现Token校验
方法一:AOP
代码如下定义一个权限注解
[java] view plain copy
- package com.thinkgem.jeesite.common.annotation;
- import java.lang.annotation.ElementType;
- import java.lang.annotation.Retention;
- import java.lang.annotation.RetentionPolicy;
- import java.lang.annotation.Target;
- /**
- * 权限注解
- * Created by Hamming on 2016/12/26.
- */
- @Target(ElementType.METHOD)//这个注解是应用在方法上
- @Retention(RetentionPolicy.RUNTIME)
- public @interface AccessToken {
- /* String userId();
- String token();*/
- }
获取页面请求中的ID token
[java] view plain copy
- @Aspect
- @Component
- public class AccessTokenAspect {
- @Autowired
- private ApiService apiService;
- @Around("@annotation(com.thinkgem.jeesite.common.annotation.AccessToken)")
- public Object doAccessCheck(ProceedingJoinPoint pjp) throws Throwable{
- HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
- String id = request.getParameter("id");
- String token = request.getParameter("token");
- boolean verify = apiService.verifyToken(id,token);
- if(verify){
- Object object = pjp.proceed(); //执行连接点方法
- //获取执行方法的参数
- return object;
- }else {
- return ResultApp.error(3,"token失效");
- }
- }
- }
token验证类 存储用到redis
[java] view plain copy
- package com.thinkgem.jeesite.common.service;
- import com.thinkgem.jeesite.common.utils.JedisUtils;
- import io.jsonwebtoken.Jwts;
- import io.jsonwebtoken.SignatureAlgorithm;
- import io.jsonwebtoken.impl.crypto.MacProvider;
- import org.slf4j.Logger;
- import org.slf4j.LoggerFactory;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.stereotype.Service;
- import org.springframework.transaction.annotation.Transactional;
- import redis.clients.jedis.Jedis;
- import java.io.*;
- import java.security.Key;
- import java.util.Date;
- /**
- *token登陆验证
- * Created by Hamming on 2016/12/23.
- */
- @Service
- public class ApiService {
- private static final String at="accessToken";
- public static Key key;
- // private Logger logger = LoggerFactory.getLogger(getClass());
- /**
- * 生成token
- * Key以字节流形式存入redis
- *
- * @param date 失效时间
- * @param appId AppId
- * @return
- */
- public String generateToken(Date date, String appId){
- Jedis jedis = null;
- try {
- jedis = JedisUtils.getResource();
- byte[] buf = jedis.get("api:key".getBytes());
- if (buf == null) { // 建新的key
- key = MacProvider.generateKey();
- ByteArrayOutputStream bao = new ByteArrayOutputStream();
- ObjectOutputStream oos = new ObjectOutputStream(bao);
- oos.writeObject(key);
- buf = bao.toByteArray();
- jedis.set("api:key".getBytes(), buf);
- } else { // 重用老key
- key = (Key) new ObjectInputStream(new ByteArrayInputStream(buf)).readObject();
- }
- }catch (IOException io){
- // System.out.println(io);
- }catch (ClassNotFoundException c){
- // System.out.println(c);
- }catch (Exception e) {
- // logger.error("ApiService", "generateToken", key, e);
- } finally {
- JedisUtils.returnResource(jedis);
- }
- String token = Jwts.builder()
- .setSubject(appId)
- .signWith(SignatureAlgorithm.HS512, key)
- .setExpiration(date)
- .compact();
- // 计算失效秒,7889400秒三个月
- Date temp = new Date();
- long interval = (date.getTime() - temp.getTime())/1000;
- JedisUtils.set(at+appId ,token,(int)interval);
- return token;
- }
- /**
- * 验证token
- * @param appId AppId
- * @param token token
- * @return
- */
- public boolean verifyToken(String appId, String token) {
- if( appId == null|| token == null){
- return false;
- }
- Jedis jedis = null;
- try {
- jedis = JedisUtils.getResource();
- if (key == null) {
- byte[] buf = jedis.get("api:key".getBytes());
- if(buf==null){
- return false;
- }
- key = (Key) new ObjectInputStream(new ByteArrayInputStream(buf)).readObject();
- }
- Jwts.parser().setSigningKey(key).parseClaimsJws(token).getBody().getSubject().equals(appId);
- return true;
- } catch (Exception e) {
- // logger.error("ApiService", "verifyToken", key, e);
- return false;
- } finally {
- JedisUtils.returnResource(jedis);
- }
- }
- /**
- * 获取token
- * @param appId
- * @return
- */
- public String getToken(String appId) {
- Jedis jedis = null;
- try {
- jedis = JedisUtils.getResource();
- return jedis.get(at+appId);
- } catch (Exception e) {
- // logger.error("ApiService", "getToken", e);
- return "";
- } finally {
- JedisUtils.returnResource(jedis);
- }
- }
- }
spring aop配置
[html] view plain copy
- <!--aop -->
- <!-- 扫描注解bean -->
- <context:component-scan base-package="com.thinkgem.jeesite.common.aspect"/>
- <aop:aspectj-autoproxy proxy-target-class="true"/>
验证权限方法使用 直接用注解就可以了AccessToken
例如
[java] view plain copy
- package com.thinkgem.jeesite.modules.app.web.pay;
- import com.alibaba.fastjson.JSON;
- import com.thinkgem.jeesite.common.annotation.AccessToken;
- import com.thinkgem.jeesite.common.base.ResultApp;
- import com.thinkgem.jeesite.modules.app.service.pay.AppAlipayConfService;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.stereotype.Controller;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.RequestMethod;
- import org.springframework.web.bind.annotation.ResponseBody;
- import java.util.HashMap;
- import java.util.Map;
- /**
- * 支付接口
- * Created by Hamming on 2016/12/27.
- */
- @Controller
- @RequestMapping(value = "/app/pay")
- public class AppPayModule {
- @Autowired
- private AppAlipayConfService appAlipayConfService;
- @RequestMapping(value = "/alipay", method = RequestMethod.POST, produces="application/json")
- @AccessToken
- @ResponseBody
- public Object alipay(String orderId){
- if(orderId ==null){
- Map re = new HashMap<>();
- re.put("result",3);
- re.put("msg","参数错误");
- String json = JSON.toJSONString(re);
- return json;
- }else {
- return null;
- }
- }
- }
方法二: MVC拦截器
服务器:
拼接token之外所有参数,最后拼接token_key,做MD5,与token参数比对
如果token比对失败返回状态码 500
[java] view plain copy
- public class APIInterceptor extends HandlerInterceptorAdapter {
- @Override
- public boolean preHandle(HttpServletRequest request,
- HttpServletResponse response, Object handler) throws Exception {
- Log.info(request);
- String token = request.getParameter("token");
- // token is not needed when debug
- if(token == null) return true; // !! remember to comment this when deploy on server !!
- Enumeration paraKeys = request.getParameterNames();
- String encodeStr = "";
- while (paraKeys.hasMoreElements()) {
- String paraKey = (String) paraKeys.nextElement();
- if(paraKey.equals("token"))
- break;
- String paraValue = request.getParameter(paraKey);
- encodeStr += paraValue;
- }
- encodeStr += Default.TOKEN_KEY;
- Log.out(encodeStr);
- if ( ! token.equals(DigestUtils.md5Hex(encodeStr))) {
- response.setStatus(500);
- return false;
- }
- return true;
- }
- @Override
- public void postHandle(HttpServletRequest request,
- HttpServletResponse response, Object handler,
- ModelAndView modelAndView) throws Exception {
- Log.info(request);
- }
- @Override
- public void afterCompletion(HttpServletRequest request,
- HttpServletResponse response, Object handler, Exception ex)
- throws Exception {
- }
- }
spring-config.xml配置中加入
[html] view plain copy
- <mvc:interceptors>
- <mvc:interceptor>
- <mvc:mapping path="/api/*" />
- <bean class="cn.web.interceptor.APIInterceptor" />
- </mvc:interceptor>
- </mvc:interceptors>
客户端:
拼接请求接口的所有参数,最后拼接token_key,做MD5,作为token参数
请求样例:http://127.0.0.1:8080/interface/api?key0=param0&key1=param1&token=md5(concat(param0, param1))
api测试页面,用到了Bootstrap和AngularJS,还有一个js的hex_md5函数
[html] view plain copy

- if(params[0] != undefined && values[0] != undefined && values[0] != ‘‘)
- addr += ‘?‘ + params[0] + "=" + values[0];
- for(var i=1; i < values.length; i++)
- if(params[i] != undefined && values[i] != undefined && values[i] != ‘‘)
- addr += "&" + params[i] + "=" + values[i];
- return addr;
- }
- }
- function APIListCtrl($scope) {
- $scope.md5 = hex_md5;

- $scope.concat = function(){

- args.push($scope.token_key);
- return args.join("");
- }
