class="post-body" itemprop="articleBody"><p>因为活实在比较多，也不太好叫大工(活比较杂散)，相比上一次我跟 LD 俩人晚起了一点，我真的是只要有事，早上就醒的很早，准备八点出发的，六点就醒了，然后想继续睡就一直做梦🤦‍♂️，差不多八点半多到的丈人家，他们应该已经干了有一会了，我们到了以后就分配给我撬地板的活，上次说的那个敲掉柜子的房间里，还铺着质地还不错的木地板，但是也不想要了，得撬掉重新铺。<br>拿着撬棍和榔头就上楼去干了，浙江这几天的天气，最高温度一般 38、9，楼上那个房间也没风扇，有了也不能用，都是灰尘，撬了两下，我感觉我体内的水就像真气爆发一样变成汗炸了出来，眼睛全被汗糊住了，可能大部分人不太了解地板是怎么铺的，一般是在地面先铺一层混凝土，混凝土中间嵌进去规则的长条木条，然后真正的地板一块块的都是钉在那个木条上，用那种气枪钉和普通的钉子，并且块跟块之前还有一个木头的槽结构相互耦合，然后边缘的一圈在用较薄的木板将整个木地板封边(这些词都是我现造的)，边缘的用的钉子会更多，所以那几下真的很用力，而且撬地板，得蹲下起来，如此反复，对于我这个体重快超过身高的中年人来说的确是非常大的挑战，接下来继续撬了几个，已经有种要虚脱晕倒的感觉了，及时去喝水擦了汗，又歇了一会，为啥一上来就这么拼呢，主要是因为那个房间丈人在干活的时候是直接看得到的🤦‍♂️，后来被 LD 一顿教育，本来就是去帮忙的，又不是专业做这个的，急啥。<br>喝了水之后，又稍稍歇了一会，就开始继续撬了，本来觉得这个地板撬着好像还行，房间不大，没多久就撬完了，撬完之后喝了点饮料(补充点糖分，早餐吃得少，有点低血糖)，然后看到 LD 在撬下面的木条了，这个动作开始了那天最大的经验值收集行动，前面说了这个木条一般是跟混凝土一块铺上去的，但是谁也没想到，这个混凝土铺上去的时候竟然处理的这么随意，根本没考虑跟下面的贴合，所以撬木条的时候直接把木条跟木条中间大块大块的混凝土一块撬起来了，想想那重量，于是我这靠蛮力干活的，就用力把木条带着混凝土一块撬了起来，还沾沾自喜，但是发现结果是撬起来一块之后，体力值瞬间归零，上一篇我也提到了，其实干这类活也是很有技巧性的，但是上次的是我没学会，可能需要花时间学的，但是这次是LD 用她的纤细胳膊教会我的，我在撬的时候，屏住一口气，双手用力，起，大概是吃好几口奶的力气都用出来了，但是 LD 在我休息的时候，慢慢悠悠的，先把撬棍挤到木条或者混凝土跟下层的缝里，然后往下垫一小块混凝土碎石，然后轻轻松松的扳两下，就撬开了，亏我高中的时候引以为傲的物理成绩，作为物理课代表，这么浅显易懂的杠杆原理都完全不会用到生活里，后面在用这个技巧撬的过程中，真的觉得自己蠢到家了，当然在明白了用点杠杆原理之后，撬地板的活就变得慢慢悠悠，悠哉悠哉的了(其实还是很热的，披着毛巾擦眼睛)。<br>上午的活差不多完了，后面就是把撬出来的混凝土和地板条丢下去，地上铺着不用了的被子，然后就是午饭和午休环节了，午饭换了一家快餐，味道非常可以，下午的活就比较单调了，帮忙清理了上去扔下来的混凝土碎块跟木条，然后稍微打扫了下，老丈人就让我们回家了，接着上次说的，还是觉得比跑步啥的消耗大太多了，那汗流的，一口就能喝完一瓶 500 毫升左右的矿泉水。</p></div><footer class="post-footer"><div class="post-eof"></div></footer></article></div><div class="post-block"><article itemscope itemtype="http://schema.org/Article"

itemprop="articleBody"><p>本来是想取个像现在那些公众号转了又转的文章标题，”面试官再问你xxxxx，就把这篇文章甩给他看”这种标题，但是觉得实在太 low 了，还是用一部我比较喜欢的电影里的一句台词，《人在囧途》里王宝强对着那张老板给他的欠条，看不懂字时候说的那句，这些都是些啥（第四声）<br>当我刚开始面 Java 的时候，其实我真的没注意这方面的东西，实话说就是不知道这些是啥，开发中用过 Interceptor和 Aop，了解 aop 的实现原理，但是不知道 Java web 中的 Filter 是怎么回事，知道 dubbo 的 filter，就这样，所以被问到了的确是回答不出来，可能就觉得这个渣渣，这么简单的都不会，所以还是花点时间来看看这个是个啥，为了避免我口吐芬芳，还是耐下性子来简单说下这几个东西<br>首先是 servlet，怎么去解释这个呢，因为之前是 PHPer，所以比较喜欢用它来举例子，在普通的 PHP 的 web 应用中一般有几部分组成，接受 HTTP 请求的是前置的 nginx 或者 apache，但是这俩玩意都是只能处理静态的请求，远古时代 PHP 和 HTML 混编是通过 apache 的 php module，跟后来 nginx 使用 php-fpm 其实道理类似，就是把请求中需要 PHP 处理的转发给 PHP，在 Java 中呢，是有个比较牛叉的叫 Tomcat 的，它可以把请求转成 servlet，而 servlet 其实就是一种实现了特定接口的 Java 代码，</p><pre class="line-numbers language-java" data-language="java"><code class="language-java">

* Defines methods that all servlets must implement.
*
* &lt;p>
* A servlet is a small Java program that runs within a Web server. Servlets
* receive and respond to requests from Web clients, usually across HTTP, the
* HyperText Transfer Protocol.
*
* &lt;p>
* To implement this interface, you can write a generic servlet that extends
* &lt;code>javax.servlet.GenericServlet&lt;/code> or an HTTP servlet that extends
* &lt;code>javax.servlet.http.HttpServlet&lt;/code>.
*
* &lt;p>
* This interface defines methods to initialize a servlet, to service requests,
* and to remove a servlet from the server. These are known as life-cycle
* methods and are called in the following sequence:
* &lt;ol>
* &lt;li>The servlet is constructed, then initialized with the &lt;code>init&lt;/code>
* method.
* &lt;li>Any calls from clients to the &lt;code>service&lt;/code> method are handled.
* &lt;li>The servlet is taken out of service, then destroyed with the
* &lt;code>destroy&lt;/code> method, then garbage collected and finalized.
* &lt;/ol>
*
* &lt;p>
* In addition to the life-cycle methods, this interface provides the
* &lt;code>getServletConfig&lt;/code> method, which the servlet can use to get any
* startup information, and the &lt;code>getServletInfo&lt;/code> method, which allows
* the servlet to return basic information about itself, such as author,
* version, and copyright.
*
* @see GenericServlet
* @see javax.servlet.http.HttpServlet

itemprop="articleBody"><p>这周回家提前约好了要去老丈人家帮下忙，因为在翻修下老房子，活不是特别整的那种，所以大部分都是自己干，或者找个大工临时干几天（我们这那种比较专业的泥工匠叫做大工），像我这样去帮忙的，就是干点小工（把给大工帮忙的，干些偏体力活的叫做小工）的活。从大学毕业以后真的蛮少帮家里干活了，以前上学的时候放假还是帮家里淘个米，简单的扫地拖地啥的，当然刚高考完的时候，还去我爸厂里帮忙干了几天的活，实在是比较累，不过现在想着是觉得自己那时候比较牛，而不是特别排斥这个活，相对于现在的工作来说，导致了一系列的职业病，颈椎腰背都很僵硬，眼镜也不好，还有反流，像我爸那种活反而是脑力加体力的比较好的结合。<br>这一天的活前半部分主要是在清理厨房，瓷砖上的油污和墙上天花板上即将脱落的石灰或者白色涂料层，这种活特别是瓷砖上的油污，之前在自己家里也干活，还是比较熟悉的，不过前面主要是LD 在干，我主要是先搞墙上和天花板上的，干活还是很需要技巧的，如果直接去铲，那基本我会变成一个灰人，而且吸一鼻子灰，老丈人比较专业，先接上软管用水冲，一冲效果特别好，有些石灰涂料层直接就冲掉了，冲完之后先用带加长杆的刀片铲铲了一圈墙面，说实话因为老房子之前租出去了，所以墙面什么的被糟蹋的比较难看，一层一层的，不过这还算还好，后面主要是天花板上的，这可难倒我了，从小我爸妈是比较把我当小孩管着，爬上爬下的基本都是我爸搞定，但是到了老丈人家也只得硬着头皮上了，爬到跳（一种建筑工地用的架子）上，还有点晃，小心脏扑通扑通跳，而且带加长杆的铲子还是比较重的，铲一会手也有点累，不过坚持着铲完了，上面还是比较平整的，不过下来的时候又把我难住了🤦‍♂️，往下爬的时候有根杆子要跨过去，由于裤子比较紧，强行一把跨过去怕抽筋，所以以一个非常尴尬的姿势停留休息了一会，再跨了过去，幸好事后问 LD，他们都没看到，哈哈哈，然后就是帮忙一起搞瓷砖上的油污，这个太有经验了，不过老丈人更有意思，一会试试啤酒，一会用用沙子，后面在午饭前基本就弄的比较干净了，就坐着等吃饭了，下午午休了会，就继续干活了。<br>下午是我这次体验的重点了，因为要清理以前贴的墙纸，真的是个很麻烦的活，只能说贴墙纸的师傅活干得太好了，基本不可能整个撕下来，想用铲子一点点铲下来也不行，太轻了就只铲掉表面一层，太重了就把墙纸跟墙面的石灰啥的整个铲下来了，而且手又累又酸，后来想着是不是继续用水冲一下，对着一小面墙试验了下，效果还不错，但是又发现了个问题，那一面墙又有一块是后面糊上去的，铲掉外层的石灰后不平，然后就是最最重头的，也是让我后遗症持续到第二天的，要把那一块糊上去的水泥敲下来，毛估下大概是敲了80%左右，剩下的我的手已经不会用力了，因为那一块应该是要糊上去的始作俑者，就一块里面凹进去的，我拿着榔头敲到我手已经没法使劲了，而且大下午，感觉没五分钟，我的汗已经糊满脸，眼睛也睁不开，不然就流到眼睛里了，此处获得成就一：用榔头敲墙壁，也是个技术加体力的活，而且需要非常好的技巧，否则手马上就废了，敲下去的反作用力，没一会就不行了，然后是看着老丈人兄弟帮忙拆一个柜子，在我看来是个几天都搞不定的活，他轻轻松松在我敲墙的那会就搞定了，以前总觉得我干的活非常有技术含量，可是这个事情真的也是很有技巧啊，它是个把一间房间分隔开的柜子，从底到顶上，还带着门，我还在旁边帮忙撬一下脚踢，一根木条撬半天，唉，成就二：专业的人就是不一样。<br>最后就是成就三了：我之前沾沾自喜的跑了多少步，做了什么锻炼，其实都是渣渣，像这样干一天活，没经历过的，基本大半天就废了，反过来说，如果能经常去这么干一天活，跑步啥的都是渣渣，消耗的能量远远超过跑个十公里啥的。</p></div><footer

data-src="https://img.nicksxs.com/uPic/a1I2vj.png"><br>上面比较长，把主要的截出来，就是这边的，这点就很强大了。</p><h3 id="jmap"><a href="#jmap" class="headerlink" title="jmap"></a>jmap</h3><p>惯例还是看一下帮助信息<br><img data-src="https://img.nicksxs.com/uPic/dBiPqS.png"><br>这个相对命令比较多，不过因为现在 dump 下来我们可能会用文件模式，然后将文件下载下来使用 mat 进行分析，所以可以使用<br><code>jmap -dump:live,format=b,file=heap.bin &lt;pid&gt;</code><br>命令照着上面看的就是打印活着的对象，然后以二进制格式，文件名叫 heap.bin 然后最后就是进程 id，打印出来以后可以用 mat 打开<br><img data-src="https://img.nicksxs.com/uPic/NRWowU.png"><br>这样就可以很清晰的看到应用里的各种信息，jmap 直接在命令中还可以看很多信息，比如使用<code>jmap -histo &lt;pid&gt;</code>打印对象的实例数和对象占用的内存<br><img data-src="https://img.nicksxs.com/uPic/1GTBrY.png"><br><code>jmap -finalizerinfo &lt;pid&gt;</code> 打印正在等候回收的对象<br><img

可能会连不上的情况，可以使用<code>-F</code>参数强制打印线程或者 dump 文件，但是要注意这两者使用的用户必须与 java 进程启动用户一致，并且使用的 jdk 也要一致</p></div><footer class="post-footer"><div class="post-eof"></div></footer></article></div><nav
