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 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;    }    /**     * 使用javassist来获取方法参数名称     *     * @param class_name  类名     * @param method_name 方法名     * @return     * @throws Exception     */    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;    }    /**     * 打印方法参数值  基本类型直接打印，非基本类型需要重写toString方法     *     * @param paramsArgsName  方法参数名数组     * @param paramsArgsValue 方法参数值数组     */    private SortedMap logParam(String[] paramsArgsName, Object[] paramsArgsValue) {        Map 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);    }    /**     * 判断是否为基本类型：包括String     *     * @param clazz clazz     * @return true：是;     false：不是     */    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 parameters) {        StringBuffer sb = new StringBuffer();        for (Map.Entry 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

/** * @author xxx */@Retention(value = RetentionPolicy.RUNTIME)public @interface SignatureValidation {}

aop实现

/** * @author xxx */@Aspect@Componentpublic 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 = "" ;        String version = "";        SortedMap sortedMap = new TreeMap();        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 keySet = dataJson.keySet();                    String key = "";                    Object value = null;                    // 遍历json数据，添加到SortedMap对象                    for (Iterator 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());            }    }    /**     *     * @param point     * @param responseObject 返回参数     */    @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 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 createParameters(ResponseModel responseModel){        SortedMap sortedMap = new TreeMap();        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

import javax.servlet.*;import javax.servlet.annotation.WebFilter;import javax.servlet.http.HttpServletRequest;import java.io.IOException;/** * @author xx */@WebFilter(urlPatterns = "/*",filterName = "channelFilter")public class ChannelFilter implements Filter {    @Override    public void init(FilterConfig filterConfig) throws ServletException {    }    @Override    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {        ServletRequest requestWrapper = null;        if(servletRequest instanceof HttpServletRequest) {            requestWrapper = new RequestWrapper((HttpServletRequest) servletRequest);        }        if(requestWrapper == null) {            filterChain.doFilter(servletRequest, servletResponse);        } else {            filterChain.doFilter(requestWrapper, servletResponse);        }    }    @Override    public void destroy() {    }}

拦截器配置

import org.springframework.boot.web.servlet.FilterRegistrationBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.servlet.HandlerInterceptor;import org.springframework.web.servlet.config.annotation.CorsRegistry;import org.springframework.web.servlet.config.annotation.InterceptorRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;/** * @author xxxx */@Configurationpublic class InterceptorConfig implements WebMvcConfigurer{    @Override    public void addInterceptors(InterceptorRegistry registry) {        registry.addInterceptor(getHandlerInterceptor());    }    @Override    public void addCorsMappings(CorsRegistry registry) {        registry.addMapping("/**")                .allowedHeaders("Content-Type", "x-requested-with", "X-Custom-Header")                .allowedMethods("PUT", "POST", "GET", "DELETE", "OPTIONS")                .allowedOrigins("*")                .allowCredentials(true);    }    @Bean    public FilterRegistrationBean repeatedlyReadFilter() {        FilterRegistrationBean registration = new FilterRegistrationBean();        ChannelFilter repeatedlyReadFilter = new ChannelFilter();        registration.setFilter(repeatedlyReadFilter);        registration.addUrlPatterns("/*");        return registration;    }    @Bean    public HandlerInterceptor getHandlerInterceptor() {        return new TimestampInterceptor();    }}

RequestWrapper 请求流重写处理

import javax.servlet.ReadListener;import javax.servlet.ServletInputStream;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletRequestWrapper;import java.io.*;/** * @author xxx */public class RequestWrapper extends HttpServletRequestWrapper {    private final String body;    public RequestWrapper(HttpServletRequest request) {        super(request);        StringBuilder stringBuilder = new StringBuilder();        BufferedReader bufferedReader = null;        InputStream inputStream = null;        try {            inputStream = request.getInputStream();            if (inputStream != null) {                bufferedReader = new BufferedReader(new InputStreamReader(inputStream));                char[] charBuffer = new char[128];                int bytesRead = -1;                while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {                    stringBuilder.append(charBuffer, 0, bytesRead);                }            } else {                stringBuilder.append("");            }        } catch (IOException ex) {        } finally {            if (inputStream != null) {                try {                    inputStream.close();                }                catch (IOException e) {                    e.printStackTrace();                }            }            if (bufferedReader != null) {                try {                    bufferedReader.close();                }                catch (IOException e) {                    e.printStackTrace();                }            }        }        body = stringBuilder.toString();    }    @Override    public ServletInputStream getInputStream() throws IOException {        final ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(body.getBytes());        ServletInputStream servletInputStream = new ServletInputStream() {            @Override            public boolean isFinished() {                return false;            }            @Override            public boolean isReady() {                return false;            }            @Override            public void setReadListener(ReadListener readListener) {            }            @Override            public int read() throws IOException {                return byteArrayInputStream.read();            }        };        return servletInputStream;    }    @Override    public BufferedReader getReader() throws IOException {        return new BufferedReader(new InputStreamReader(this.getInputStream()));    }    public String getBody() {        return this.body;    }}

拦截器 这里可以实现请求来的签名处理，这里只处理时间了

返回给前端(或其他平台的)处理类
