直接上代码，作为记录。
CheckSignAspect.java

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;
}
/**
* 使用javassist来获取方法参数名称
*
* @param class_name 类名
* @param method_name 方法名

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);

for (int i = 0; i < paramsArgsName.length; i++) {

// }
if (isPrimite(value.getClass())) {

map.put(name, value.toString());
}
}
return new TreeMap<>(map);
}
/**

*

*/
private boolean isPrimite(Class<?> clazz) {
if (clazz.isPrimitive() || clazz == String.class) {
return true;
} else {

}
}
}SignUtil.java

}
}

}
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)")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。
自定义注解体
/**
* @author xxx
*/
@Retention(value = RetentionPolicy.RUNTIME)
public @interface SignatureValidation {
}aop实现
/**
* @author xxx
*/
@Aspect
@Component
public class SignatureValidation {
/**
* 时间戳请求最小限制(600s)
* 设置的越小，安全系数越高，但是要注意一定的容错性
*/
private static final long MAX_REQUEST = 10 * 60 * 1000L;
/**
* 秘钥
*/
private static final String SECRET= "test";
/**
* 验签切点(完整的找到设置的文件地址)
*/
@Pointcut("execution(@com.xx.xxx.xxxxx.aop.SignatureValidation * *(..))")
private void verifyUserKey() {
}
/**
* 获取请求数据，并校验签名数据
*/
@Before("verifyUserKey()")
public void doBasicProfiling(JoinPoint point) {
ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
HttpServletRequest request = Objects.requireNonNull(attributes).getRequest();
String sign = "" ;
String timestamp = "" ;

SortedMap<String,String> sortedMap = new TreeMap<String,String>();

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
/**
* @author xxx
*/
public class Md5Utils {
/**
* 生成签名
* @param parameters
* @param key 商户ID
* @return
*/
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;
}
/**
* 签名参数
* @param responseModel 响应数据签名返回给调用者
* @return
*/
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
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。
