spring boot 对某个接口进行次数限制,防刷。简易版。demo。

一般的项目 如果没有做防刷 容易被人爆接口 或者就是说没有做token防刷过滤。 容易被人用正常的token刷接口。有些token非一次性。 用户登录之后生成token会有一个过期时间,但一般没有做频率检查,每访问一次,会延长这个token时间,刷新用户状态 另一种就是养号,拿着真实的token,哪怕你是5分钟 1分钟。 很多的网站找回密码的接口是没有做防刷的,只是检查token是否正常。 通过验证码认证当前用户,是否为当前用户。 前几天,就用多线程刷过一个三方网站的找回密码。成功改掉密码。 一般的网站在改密码的接口都会先查一次此号码是否已经注册,相反就可以通过这个接口猜出真实的用户手机号, 然后多线程调这个接口猜验证码,一般为4位,复杂点的为6位。也会有一些项目加了图形拖拽(第三方) 前端会提交相关信息给第三方平台,分析你是不是正常的用户动作,直接封IP。 但是用户体验差一点,有些网站为了用户体验,忽略了网站安全性,看业务上的取舍了。 进入正题:简易版(demo)   aop 实现 : package com.zhouixi.serviceA.aspect; import java.lang.reflect.Method; import java.util.Arrays; import java.util.HashMap; import java.util.Map; import

slf4j does not find log4j2 jars

旧时模样 提交于 2021-01-29 21:55:09
问题 I know it should be easy to use SLF4J with Log4j2 as logger implementation. You just need to add the jars to the classpath. I have thought that I did so, but I am still getting INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time. SLF4J: Failed to load class "org.slf4j.impl

Application not writing logs on when log file rotates

独自空忆成欢 提交于 2021-01-29 08:20:35
问题 My app is using spring log4j2 and uses slf4j api to write log to separate log file "application.log". This app gets deployed to tomcat v8 along with other apps. All app share common log4j2 configuration and writes to common logfile 'application.log'. We have a log rotation policy of 250 mb and when the log file rotates the logs are not written to the logfile surprising only one app among all the app is able to write to the log file. I'm able to reproduce this locally too. Can you please help

How to import StructuredArgument for structured logging in scala using slf4j and logback

旧时模样 提交于 2021-01-28 09:56:44
问题 This is probably a stupid question, but my scala knowledge is a bit lacking. I'm trying to implement structured logging in scala, and we're using slf4j/logback/logstash. I came across the following post: How does SLF4J support structured logging Which describes how to do it: import static net.logstash.logback.argument.StructuredArguments.*; /* * Add "name":"value" ONLY to the JSON output. * * Since there is no parameter for the argument, * the formatted message will NOT contain the key/value.

Java常用第三方库大全

一、JAVA核心扩展   JAVA的标准库虽然提供了那些最基本的数据类型操作方法,但仍然对一些常见的需求场景,缺少实用的工具类。而另一些则是JAVA标准库本身不够完善,需要第三方库去加以补充的。   1、Apache Commons Lang   Apache Commons Lang是Apache最著名的JAVA库 (GitHub上的代码库),它是对java.lang的很好扩展,包含了大量非常实用的工具类,其中用的最多的有StringUtils,DateUtils,NumberUtils等。   除了Apache Commons Lang,还有一些其他的Apache库也是对JAVA本身的很好补充,如Apache Commons Collection,Apache Commons IO,Apache Commons Math   2、Google Cuava   Google Cuava包含了Google在自己的JAVA项目中所使用的一些核心JAVA库。包含了对:集合,缓存,并发库,字符串处理, I/O等各个方面的支持。另外Google开发的库总是以性能著称。   3、Joda-Time   Java SE 8之前的JAVA版本中对日期的支持是比较差的,Joda-Time被经常被使用来替换原有的日期系统,它能够支持更多的日历体系,并提供了很多非常方便的日期处理方法

How to log exception and message with placeholders with SLF4J

落花浮王杯 提交于 2021-01-20 14:44:28
问题 What's the correct approach to log both an error message and an exception using SLF4J? I've tried doing this but the exception stack trace is never printed: logger.error("Unable to parse data {}", inputMessage, e); In this case I want to populate {} with the inputMessage as well as logging out the exception stacktrace. The only way I can see to do this would be to do this: logger.error("Unable to parse data " + inputMessage, e); which is not pretty. 回答1: As of SLF4J version 1.6, SLF4J will
