SOA中springmvc中restful服务的数据权限加密方式分享
restful中数据权限加密方式有很多种,特别是针对于request json的方式加密,这里详细介绍了SOA中针对于get、post数据加密方式,保证数据传输中的安全性:
@Component("dataSignInterceptor") public class DataSignInterceptor implements MethodInterceptor { @Autowired private SoaServiceConfigService soaServiceConfigService; @Autowired private SoaAppSecretService soaAppSecretService; @Autowired private SoaServiceApplyService soaServiceApplyService; public Object invoke(MethodInvocation mi) throws Throwable { //TODO 此处应该先查询缓存 //获取所有未管控的服务列表 List<SoaServiceConfig> soaServiceConfigList = soaServiceConfigService.findNoSwitchList(); if(soaServiceConfigList != null){ //放入缓存 } Object[] ars = mi.getArguments(); // 判断该方法是否加了DataSign 注解 if (mi.getMethod().isAnnotationPresent(DataSign.class)) { // 获取拦截方法的请求参数 HttpServletRequest request = null; JSONObject jsonBody = null; Map<String, String> reqGetParamMap = null; // 客户端传递的参数信息 Map<String, String> reqPostParamMap = null; // 客户端传递的参数信息 Map<String, String> resultParamMap = new HashMap<String, String>(); for (Object obj : ars) { if (obj instanceof HttpServletRequest) { request = (HttpServletRequest) obj; reqGetParamMap = (Map<String, String>) request.getParameterMap(); Set keSet = reqGetParamMap.entrySet(); for (Iterator itr = keSet.iterator(); itr.hasNext();) { Map.Entry me = (Map.Entry) itr.next(); String key = me.getKey().toString(); Object ov = me.getValue(); String[] value =new String[1]; if(ov instanceof String[]){ value=(String[])ov; }else{ value[0]=ov.toString(); } resultParamMap.put(key, value[0]); } } else if (obj instanceof JSONObject) { jsonBody = (JSONObject) obj; ObjectMapper objMap = new ObjectMapper(); reqPostParamMap = objMap.readValue(jsonBody.toString(), Map.class); resultParamMap = reqPostParamMap; } } String serviceUrl = request.getServletPath(); if(StringUtils.isNotEmpty(serviceUrl)){ serviceUrl = serviceUrl.substring(serviceUrl.indexOf("/",2)); } //TODO 应该从缓存取,当前先这样处理 //如果所有未管控的服务列表中包含用户请求的服务连接,则不需要再进行管控,直接放开服务控制权 if(soaServiceConfigList != null){ for(SoaServiceConfig soaServiceConfig : soaServiceConfigList){ if(serviceUrl.equals(soaServiceConfig.getServiceUrl())){ return mi.proceed(); } } } String reqSign = resultParamMap.get("sign");// 客户端传递的签名认证信息 // 验证签名不能为空 if (StringUtils.isEmpty(reqSign)) { return new ResponseVO(DataSignEnum.SIGN_NOT_NULL.getCode(), DataSignEnum.SIGN_NOT_NULL.getMessage(), null); } String appname = resultParamMap.get("appname"); // 验证应用名不能为空 if (StringUtils.isEmpty(appname)) { return new ResponseVO(DataSignEnum.APPNAME_NOT_NULL.getCode(), DataSignEnum.APPNAME_NOT_NULL.getMessage(), null); } SoaServiceApply soaServiceApply = soaServiceApplyService.getServiceApplyByAppname(serviceUrl, appname); if(null == soaServiceApply){ return new ResponseVO(DataSignEnum.APPNAME_NOT_APPLY.getCode(), DataSignEnum.APPNAME_NOT_APPLY.getMessage(), null); } SoaAppSecret soaAppSecret = soaAppSecretService.findAppSecretByAppName(appname); if(null == soaAppSecret){ return new ResponseVO(DataSignEnum.APPNAME_NOT_EXISTS.getCode(), DataSignEnum.APPNAME_NOT_EXISTS.getMessage(), null); } // 根据参数重新生成新的签名sign(因为sign不能认为是业务参数,故将sign从map中移除后再加密) resultParamMap.remove("sign"); resultParamMap.put("token", soaAppSecret.getToken()); String sign = MD5Utils.paramString(resultParamMap); // 根据应用名获取应用名对应的秘钥(目的是和url请求的参数一起进行签名认证) if (!StringUtils.equals(sign, reqSign)) { return new ResponseVO(DataSignEnum.SIGN_NOT_MATCH.getCode(), DataSignEnum.SIGN_NOT_MATCH.getMessage(), null); } } // 执行被拦截的方法,切记,如果此方法不调用,则被拦截的方法不会被执行。 return mi.proceed(); } /** * 数据签名枚举 * * @author Administrator */ public enum DataSignEnum { SIGN_NOT_NULL(2001, "签名不能为空."), SIGN_NOT_MATCH(2002, "签名不匹配,传递的数据被篡改过."), APPNAME_NOT_NULL(2003, "应用名不能为空."), APPNAME_NOT_EXISTS(2004, "应用名不存在."), APPNAME_NOT_APPLY(2005, "当前应用没有权限访问此服务,请联系管理员进行服务申请."); // 成员变量 private int code; // 状态码 private String message; // 返回消息 // 构造方法 private DataSignEnum(int code, String message) { this.code = code; this.message = message; } public int getCode() { return code; } public void setCode(int code) { this.code = code; } public String getMessage() { return message; } public void setMessage(String message) { this.message = message; } } }
到此结束!!
