aop配合反射统一签名验证
直接上代码，作为记录。
CheckSignAspect.java
@Aspect //定义一个切面@Configuration@Log4j2public class CheckSignAspect { // 定义切点Pointcut @Pointcut("execution(* com.lsj.xxl.controller.*.*CheckSign(..))") public void excudeService() { } @Around("excudeService()") public Object doAround(ProceedingJoinPoint pjp) throws Throwable { String class_name = pjp.getTarget().getClass().getName(); String method_name = pjp.getSignature().getName(); String[] paramNames = getFieldsName(class_name, method_name); Object[] method_args = pjp.getArgs(); SortedMap<String, String> map = logParam(paramNames, method_args); if (map != null) { String sign = map.get("sign").toUpperCase(); map.remove("sign"); String realSign = SignUtil.createSign("utf8", map); if (!realSign.equals(sign)) { return "签名校验错误"; } } Object result = pjp.proceed(); return result; } private String[] getFieldsName(String class_name, String method_name) throws Exception { Class<?> clazz = Class.forName(class_name); String clazz_name = clazz.getName(); ClassPool pool = ClassPool.getDefault(); ClassClassPath classPath = new ClassClassPath(clazz); pool.insertClassPath(classPath); CtClass ctClass = pool.get(clazz_name); CtMethod ctMethod = ctClass.getDeclaredMethod(method_name); MethodInfo methodInfo = ctMethod.getMethodInfo(); CodeAttribute codeAttribute = methodInfo.getCodeAttribute(); LocalVariableAttribute attr = (LocalVariableAttribute) codeAttribute.getAttribute(LocalVariableAttribute.tag); if (attr == null) { return null; } String[] paramsArgsName = new String[ctMethod.getParameterTypes().length]; int pos = Modifier.isStatic(ctMethod.getModifiers()) ? 0 : 1; for (int i = 0; i < paramsArgsName.length; i++) { paramsArgsName[i] = attr.variableName(i + pos); } return paramsArgsName; } private SortedMap<String, String> logParam(String[] paramsArgsName, Object[] paramsArgsValue) { Map<String, String> map = new HashMap(); if (ArrayUtils.isEmpty(paramsArgsName) || ArrayUtils.isEmpty(paramsArgsValue)) { log.info("该方法没有参数"); return null; }// StringBuffer buffer = new StringBuffer(); for (int i = 0; i < paramsArgsName.length; i++) { //参数名 String name = paramsArgsName[i]; //参数值 Object value = paramsArgsValue[i];// if ("sign".equals(name)){// continue;// } if (isPrimite(value.getClass())) { map.put(name, String.valueOf(value)); } else { map.put(name, value.toString()); } } return new TreeMap<>(map); } private boolean isPrimite(Class<?> clazz) { if (clazz.isPrimitive() || clazz == String.class) { return true; } else { return false; } }}SignUtil.java
public class SignUtil { public static String createSign(String characterEncoding, SortedMap<String, String> parameters) { StringBuffer sb = new StringBuffer(); for (Map.Entry<String, String> entry : parameters.entrySet()) { if (!Strings.isNullOrEmpty(entry.getValue()) && !"sign".equals(entry.getKey()) && !"key".equals(entry.getKey())) { sb.append(entry.getKey() + "=" + entry.getValue() + "&"); } } String s = sb.toString(); if (s.length() > 0) { s = s.substring(0, sb.toString().length() - 1); } System.out.println("待加密字符串:" + s); String sign = MD5Util.MD5Encode(s, characterEncoding).toUpperCase(); return sign; }}
测试
@PostMapping("test1") public String bbCheckSign( @RequestParam("value") String value, @RequestParam("bb")String bb, @RequestParam("sign")String sign){ return "ok"; }
补充：
上述方式也可换为注解实现，具体修改代码如下：
添加注解
@Target(ElementType.METHOD)@Retention(RetentionPolicy.RUNTIME )public @interface CheckSign {}
改变切点
@Pointcut("@annotation(com.lsj.xxl.annotation.CheckSign)")接口统一签名校验
实现接口请求签名校验，时间戳判断，响应数据返回签名等内容。
这个签名校验，和返回签名可以用多种方法实现。
第一种aop 方式实现
自定义注解体
@Retention(value = RetentionPolicy.RUNTIME)public @interface SignatureValidation {}aop实现
@Aspect@Componentpublic class SignatureValidation { private static final long MAX_REQUEST = 10 * 60 * 1000L; private static final String SECRET= "test"; @Pointcut("execution(@com.xx.xxx.xxxxx.aop.SignatureValidation * *(..))") private void verifyUserKey() { } @Before("verifyUserKey()") public void doBasicProfiling(JoinPoint point) { ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes(); HttpServletRequest request = Objects.requireNonNull(attributes).getRequest(); String sign = "" ; String timestamp = "" ; String version = ""; SortedMap<String,String> sortedMap = new TreeMap<String,String>(); for ( Object obj :point.getArgs()) { JSONObject jsonObject =JSONUtil.parseObj(obj); if( !StrUtil.isEmptyIfStr(jsonObject.get("sign"))){ sign=jsonObject.get("sign").toString(); } if(!StrUtil.isEmptyIfStr(jsonObject.get("timestamp"))){ timestamp=jsonObject.get("timestamp").toString(); sortedMap.put("timestamp", timestamp); } if(!StrUtil.isEmptyIfStr(jsonObject.get("version"))){ version=jsonObject.get("version").toString(); sortedMap.put("version", version); } if(!StrUtil.isEmptyIfStr(jsonObject.get("data"))){ String dataStr= jsonObject.get("data").toString(); if(!JSONUtil.isJsonObj(dataStr)) { if(JSONUtil.isJsonArray(dataStr)){ sortedMap.put("data", JSONUtil.parseArray(dataStr).toString()); } sortedMap.put("data", dataStr); } else { JSONObject dataJson= JSONUtil.parseObj(dataStr); @SuppressWarnings("unchecked") Set<String> keySet = dataJson.keySet(); String key = ""; Object value = null; // 遍历json数据，添加到SortedMap对象 for (Iterator<String> iterator = keySet.iterator(); iterator.hasNext();) { key = iterator.next(); value = dataJson.get(key); String valueStr=""; if(!StrUtil.isEmptyIfStr(value)){ valueStr=value.toString(); } sortedMap.put(key, valueStr); } } } } if (StrUtil.isEmptyIfStr(sign)) { throw new CustomException(BaseResultInfoEnum.ERROR_MISSING_SIGN_1009.getMsg(),BaseResultInfoEnum.ERROR_MISSING_SIGN_1009.getCode()); } //新的签名 String newSign = createSign(sortedMap,SECRET); if (!newSign.equals(sign.toUpperCase())) { throw new CustomException(BaseResultInfoEnum.ERROR_SIGN_1010.getMsg(),BaseResultInfoEnum.ERROR_SIGN_1010.getCode()); } } @AfterReturning(pointcut="verifyUserKey()",returning="responseObject") public void afterReturning(JoinPoint point,Object responseObject) { HttpServletResponse response=((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getResponse(); if(responseObject instanceof ResponseModel){ ResponseModel responseModel= (ResponseModel) responseObject; responseModel.setTimestamp(System.currentTimeMillis()); responseModel.setVersion(0); String sign= Md5Utils.createSign(Md5Utils.createParameters(responseModel),SECRET); responseModel.setSign(sign); } }}md5签名
public class Md5Utils { public static String createSign(SortedMap<String,String> parameters, String key){ StringBuffer sb = new StringBuffer(); Set es = parameters.entrySet(); Iterator it = es.iterator(); while(it.hasNext()) { Map.Entry entry = (Map.Entry)it.next(); String k = (String)entry.getKey(); Object v = entry.getValue(); if(null != v && !"".equals(v) && !"sign".equals(k) && !"key".equals(k)) { sb.append(k + "=" + v + "&"); } } sb.append("key=" + key); String sign = SecureUtil.md5(sb.toString()).toUpperCase(); return sign; } public static SortedMap<String,String> createParameters(ResponseModel responseModel){ SortedMap<String,String> sortedMap = new TreeMap<String,String>(); if(responseModel!=null) { sortedMap.put("timestamp", Convert.toStr(responseModel.getTimestamp()) ); sortedMap.put("version", Convert.toStr(responseModel.getVersion())); JSONObject json = JSONUtil.parseObj(responseModel, false); if(responseModel.getData()!=null) { sortedMap.put("data", json.get("data").toString()); } } return sortedMap; }}使用，在控制中的方法上方注解即可
第二种拦截器
这里只做了时间判断，签名校验可以根据需要修改即可实现。
过滤器
