自定义注解实现环绕增强—消息的发送

需求:audit log,针对30多个接口,需要对操作者的行为做一定对记录

实现:

注解的定义

1.使用了两种元注解,很基础,作为使用过的人,应该要知道不仅只有这两种,也不仅只是这些参数
2.type是用于业务,后面则是很简单的参数,type总共有三种,分别对应了三种场景,auditlog,securityLog,invalid message
题外话—这也是金融系统的一个特点,安全性要求高,不仅仅是基本的权限控制,服务器上云,数据库备份,容灾,
甚至在任何一次操作都会在系统中留下记录

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
public @interface Log {
    LogConstant.TypeEnum[] type();

    LogConstant.ModuleEnum module();

    LogConstant.ActionTypeEnum actionType();
}

环绕增强

一、环绕增强的基本实现
核心注解@Aspect,@Around,pjp就是切入点pjp.process之前就是前置增强,try,就是异常抛出增强
主意这里的url和ip的获取,url比较简单,ip则因为nginx,需要一点解析
二、kafka发送的业务
消息的发送有一些封装,以及多线程多使用,具体
就logService.sendAuditLog(auditLogCreateParam);还需要做分析

@Aspect
@Component
@Slf4j
@Deprecated
public class LogAspectHandler {

    @Autowired
    private LogService logService;

    @Around(value = "@annotation(logAnnotation)")
    public Object intercept(ProceedingJoinPoint proceedingJoinPoint, Log logAnnotation) throws Throwable {
        Object result;

        Map<String, Object> paramMap = new HashMap<>();
        Object[] args = proceedingJoinPoint.getArgs();
            for (Object arg : args) {
                if (arg instanceof HttpServletRequest) {
                paramMap.put("url", ((HttpServletRequest) arg).getServletPath());
                paramMap.put("clientIp", IpAddressUtil.getIpAdrress((HttpServletRequest) arg));
               // paramMap.put("userId", CookieUtil.getUsername(((HttpServletRequest) arg)));
                break;
            }
        }
        MethodSignature signature = (MethodSignature) proceedingJoinPoint.getSignature();
        final Annotation[][] annotationsArray = signature.getMethod().getParameterAnnotations();
        for (int i = 0; i < annotationsArray.length; i++) {
            for (Annotation a: annotationsArray[i]) {
                if (a instanceof RequestBody) {
                    paramMap.put("detail", JsonUtil.toJson(proceedingJoinPoint.getArgs()[i]));
                }
            }
        }

        List<LogConstant.TypeEnum> logType = Arrays.asList(logAnnotation.type());
        if (logType.contains(LogConstant.TypeEnum.AUDIT_LOG)) {
            AuditLogCreateParam auditLogCreateParam = new AuditLogCreateParam();
            auditLogCreateParam.setActionType(logAnnotation.actionType().getValue());
            auditLogCreateParam.setModule(logAnnotation.module().getValue());
            auditLogCreateParam.setOperationTime(LocalDateTime.now());
            BeanUtils.populate(auditLogCreateParam, paramMap);
            logService.sendAuditLog(auditLogCreateParam);
        }
        if (logType.contains(LogConstant.TypeEnum.SECURITY_LOG)) {
            SecurityLogCreateParam securityLogCreateParam = new SecurityLogCreateParam();
            securityLogCreateParam.setActionType(logAnnotation.actionType().toString());
            securityLogCreateParam.setModule(logAnnotation.module().getValue());
            securityLogCreateParam.setOperationTime(LocalDateTime.now());
            BeanUtils.populate(securityLogCreateParam, paramMap);
            logService.sendSecurityLog(securityLogCreateParam);
        }

        try {
            result = proceedingJoinPoint.proceed();
        } catch (Throwable e) {
            log.error("LogAspectHandler-Interceptor",e);
            throw e;
        }
        return result;
    }
}

获取ip

/**
     * 获取Ip地址
     * @param request
     * @return
     */
    public static String getIpAdrress(HttpServletRequest request) {
        String Xip = request.getHeader("X-Real-IP");
        String XFor = request.getHeader("X-Forwarded-For");
        if(StringUtils.isNotEmpty(XFor) && !"unKnown".equalsIgnoreCase(XFor)){
            //多次反向代理后会有多个ip值，第一个ip才是真实ip
            int index = XFor.indexOf(",");
            if(index != -1){
                return XFor.substring(0,index);
            }else{
                return XFor;
            }
        }
        XFor = Xip;
        if(StringUtils.isNotEmpty(XFor) && !"unKnown".equalsIgnoreCase(XFor)){
            return XFor;
        }
        if (StringUtils.isBlank(XFor) || "unknown".equalsIgnoreCase(XFor)) {
            XFor = request.getHeader("Proxy-Client-IP");
        }
        if (StringUtils.isBlank(XFor) || "unknown".equalsIgnoreCase(XFor)) {
            XFor = request.getHeader("WL-Proxy-Client-IP");
        }
        if (StringUtils.isBlank(XFor) || "unknown".equalsIgnoreCase(XFor)) {
            XFor = request.getHeader("HTTP_CLIENT_IP");
        }
        if (StringUtils.isBlank(XFor) || "unknown".equalsIgnoreCase(XFor)) {
            XFor = request.getHeader("HTTP_X_FORWARDED_FOR");
        }
        if (StringUtils.isBlank(XFor) || "unknown".equalsIgnoreCase(XFor)) {
            XFor = request.getRemoteAddr();
        }
        return XFor;
    }
