流量控制由于收发双方各自的工作速率和缓存空间的差异，可能出现发送方的发送能力大于接收方的接受能力的现象，如果此时不对发送方的发送速率进行限制，那么接收方可能会被后面不断发送来的数据“淹没”，造成帧的丢失而出错。流量控制实际上就是限制发送方的数据流量，使其发送速率不超过接收方的接收能力。
可靠传输机制数据链路层的可靠传输机制通常使用确认和超时重传两种机制完成。确认是一种无数据的控制帧，这种控制帧使得接收方可以让发送方知道哪些内容被正确接收（有些情况下为了提高传输效率，将确认捎带在一个回复帧中，称为捎带确认）。超时重传是指发送方在发送某个数据帧后就开启一个计时器，在一定时间内如果没有得到发送的数据帧的确认帧，就重新发送该数据帧，直到发送成功为止。自动重传请求（Auto Repeat reQuest，ARQ）通过接收方请求发送方重传出错的数据帧来恢复出错的帧。传统自动重传请求分为三种，停止-等待（Stop-and-wait）ARQ、后退N帧（Go-Back-N）ARQ和选择性重传（Selective Repeat）ARQ。后两种协议 ...</div></div></div><div class="recent-post-item"><div class="post_cover left"><a href="/a5d2d7c3.html" title="Mybaits 架构原理"><img class="post_bg" src="https://s2.loli.net/2022/10/01/46p5Emr3uRMd7vo.png" onerror="this.onerror=null;this.src='/img/404.jpg'" alt="Mybaits 架构原理"></a></div><div class="recent-post-info"><a class="article-title" href="/a5d2d7c3.html" title="Mybaits 架构原理">Mybaits 架构原理</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time class="post-meta-date-created" datetime="2022-10-01T05:24:18.000Z" title="发表于 2022-10-01 13:24:18">2022-10-01</time><span class="article-meta-separator">|</span><i class="fas fa-history"></i><span class="article-meta-label">更新于</span><time class="post-meta-date-updated" datetime="2022-10-09T05:56:31.363Z" title="更新于 2022-10-09 13:56:31">2022-10-09</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/Java-%E5%AD%A6%E4%B9%A0%E7%AC%94%E8%AE%B0/">Java 学习笔记</a><i class="fas fa-angle-right article-meta-link"></i><a class="article-meta__categories" href="/categories/Java-%E5%AD%A6%E4%B9%A0%E7%AC%94%E8%AE%B0/Mybatis-%E6%A1%86%E6%9E%B6/">Mybatis 框架</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/Java/">Java</a><span class="article-meta-link">•</span><a class="article-meta__tags" href="/tags/Mybatis/">Mybatis</a></span></div><div class="content">学习 Mybatis 的执行流程</div></div></div><div class="recent-post-item"><div class="post_cover right"><a href="/708392e6.html" title="解决阿里云服务器中挖矿程序"><img class="post_bg" src="https://s2.loli.net/2022/09/28/JprRdkWTvwMh68u.jpg" onerror="this.onerror=null;this.src='/img/404.jpg'" alt="解决阿里云服务器中挖矿程序"></a></div><div class="recent-post-info"><a class="article-title" href="/708392e6.html" title="解决阿里云服务器中挖矿程序">解决阿里云服务器中挖矿程序</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time class="post-meta-date-created" datetime="2022-09-29T02:31:11.000Z" title="发表于 2022-09-29 10:31:11">2022-09-29</time><span class="article-meta-separator">|</span><i class="fas fa-history"></i><span class="article-meta-label">更新于</span><time class="post-meta-date-updated" datetime="2022-10-04T09:25:37.313Z" title="更新于 2022-10-04 17:25:37">2022-10-04</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/%E7%BA%BF%E4%B8%8A%E7%AA%81%E5%8F%91%E7%8A%B6%E5%86%B5%E5%A4%84%E7%90%86/">线上突发状况处理</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/Linux/">Linux</a></span></div><div class="content">解决阿里云服务器中挖矿程序top命令看不到cpu占用特别高的进程，但是总cpu的us高达96%。

循环调用其实就是一个死循环，除非有终结条件。
Spring 中循环依赖场景有：
构造器的循环依赖（构造器注入）
Field 属性的循环依赖（set注入）
其中，构造器的循环依赖问题无法解决，只能拋出 BeanCurrentlyInCreationException 异常，在解决属性循环依赖时，spring 采用的是提前暴露对象的方法。
循环依赖处理机制
单例 bean 构造器参数循环依赖（无法解决）
prototype 原型 bean 循环依赖（无法解决）
对于原型 bean 的初始化过程中不论是通过构造器参数循环依赖还是通过 setXxx 方法产生循环依赖，Spring 都会直接报错处理。
Spring 不支持原型 bean 的循环依赖进入 AbstractBeanFactory#doGetBean 方法：
在获取 bean 之前如果这个原型 bean 正在被创建则直接抛出异常。原型 ...</div></div></div><div class="recent-post-item"><div class="post_cover left"><a href="/aad19206.html" title="Bean 创建流程"><img class="post_bg" src="https://s2.loli.net/2022/10/08/8REn1yjfUVaKosF.png" onerror="this.onerror=null;this.src='/img/404.jpg'" alt="Bean 创建流程"></a></div><div class="recent-post-info"><a class="article-title" href="/aad19206.html" title="Bean 创建流程">Bean 创建流程</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time class="post-meta-date-created" datetime="2022-06-21T10:39:27.000Z" title="发表于 2022-06-21 18:39:27">2022-06-21</time><span class="article-meta-separator">|</span><i class="fas fa-history"></i><span class="article-meta-label">更新于</span><time class="post-meta-date-updated" datetime="2022-10-08T12:03:33.227Z" title="更新于 2022-10-08 20:03:33">2022-10-08</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/Java-%E5%AD%A6%E4%B9%A0%E7%AC%94%E8%AE%B0/">Java 学习笔记</a><i class="fas fa-angle-right article-meta-link"></i><a class="article-meta__categories" href="/categories/Java-%E5%AD%A6%E4%B9%A0%E7%AC%94%E8%AE%B0/Spring-%E6%A1%86%E6%9E%B6/">Spring 框架</a></span><span class="article-meta tags"><span class="article-meta-separator">|</span><i class="fas fa-tag"></i><a class="article-meta__tags" href="/tags/Java/">Java</a><span class="article-meta-link">•</span><a class="article-meta__tags" href="/tags/Spring/">Spring</a></span></div><div class="content">调用栈
