调试代码是一�U�编码所需的基本能力，�怿�没有多少人写出来的代码能够是没有bug的，虽然传闻是有�q�这��L(f��ng)��人，因此普通的我们只能通过调试代码来查扑֒�修复代码中的问题�Q�需要调试代码的场景有很多种�Q�在�q�些场景中，也会(x��)有很多种不同的调试技巧可采用�?br />
最典型的需要调试代码的场景是单元测试的场景�Q�在单元���试时会(x��)���到代码的执行不�W�合预期或抛出意料外的异常，在碰到抛出意料外的异常时�Q�通常现在的高�U�语�a�都会(x��)提示是由于哪行代码造成的异常，于是首先的做法都是去看看对应的那行代码是什么个状况�Q�然后评估大概是什么原因造成的，如果在这�U�推���情况下无法判断问题在哪�?ji��n)的话，在没有支持程序调试时�Q�通常只能是在原始代码中输��Z��堆的信息到console�Q�例如java中就是System.out.println或System.out.err�Q�于是运行，看看console中一堆的信息�Q�然后慢慢的来推���问题，当然�Q�这也是一�U�可选的�Ҏ(gu��)���Q�甚臛_��某些场景中是一�U�不错的�Ҏ(gu��)���Q�但在各�U�IDE支持�E�序调试后，更多的时候调试都可以通过IDE来进行，发明�q�个的�h真的太伟大了(ji��n)�Q�虽然我不知道是谁，但是�q�是惌���拜下的，:)�Q�有些看似很���的功能�Q�往往非常的重要，于是现在的我们可以幸���的设个断点�Q�然后开始逐行跟踪、蟩行跟�t�、跟�t�进入函数内部、蟩出函数、跟�t�变量甚至修改变量等�{�N多种的方式幸���的调试着代码�Q�看着代码在运行时的状态，很容易的���p��我们发现代码中的问题�Q�这个绝�Ҏ(gu��)��节省�?ji��n)非帔R��常多的时��_(d��)��所以我说我很佩服那些号�U�用��C��本写代码的高手们�Q�难道他们的代码都是零bug的？要么���是��Z��(ji��n)bug后也可以一眼判定问题所在的�Q�那实在太强�?ji��n)点�Q�对于这��L(f��ng)��高手�Q�确实可以不需要IDE�q�种��C��化的武器�Q�对于我而言�Q�用��C��本写���像停留在原始时代，而IDE差不多应该到帝王时代�?ji��n)�?)�Q�开玩笑�Q�调侃下用记事本写代码的高手而言�Q�这是单元测试中的场景和通常采用的技巧�?br />
�q�有需要调试的场景通常�?x��)是集成���试场景�Q�通常�Q�集成测试会(x��)复杂很多�Q�于是要用到的调试技巧会(x��)复杂一些，���像下面�q�样的两�U�场景：(x��)<br />
1、�ƈ发程�?br />
&#160;&#160; �q�发�E�序向来���是最最复杂的，没有�����知道在运行时到底是怎么个执行顺序，否则��׃��叫�ƈ发了(ji��n)�Q?)�Q�于是，在�ƈ发程序中�Q�N多种�����无法惌���的复杂场景就出现�?ji��n)，毕竟�����的思考应该不支持�q�发的吧�Q�至���我的貌似支持不�?ji��n)，也许是我�W�，呵呵�Q�而且通常�q�发�E�序中的错误是不一定能每次都重现的�Q�这是最�ȝ��(ch��)的，至于借助IDE调试�Q�同��h��不行的，因�ؓ(f��)�q�发�E�序�׃��断点的进入可能完全被打�ؕ�Q�于是，对于�q�发�E�序�Q�通常能采用的�Ҏ(gu��)���Q�比较靠��q���Ҏ(gu��)���Q�我觉得�q�是打日志，当然�Q�你可以选择�l�箋(hu��)System.out.println、System.out.err�Q�或者采用更加高�U�和优雅点的log.debug�q�样的方法，然后���q��着旉�����x(ch��ng)��慢慢的运用自��q��大脑来思考复杂的�q�发的问题，:)�Q�这�l�对是一�U�挑(xi��)战，但因此也�?x��)带来充分的乐趣�Q�于是慢慢的享受�q�个�q�程吧�?br />
&#160;&#160; 多说一句，�q�好现在java有了(ji��n)更高�_�ֺ�的时间戳�Q�System.nanoTime�Q�用System.currentTimeInMills�Ҏ(gu��)�����没法分析�ƈ发程序，因�ؓ(f��)它的�_�ֺ�不够�?#160;<br />
2、所依赖的程序有问题<br />
&#160;&#160; �q�种场景嘛，相对而言���复杂很多了(ji��n)�Q�因为通常�q�个时候能做的多数是通知所依赖的程序方��L����N��题，但如果手头有所依赖的程序的代码的话�Q�多数可以采取跟入其源码的方式，���管不一定能修复其源码，但对于查扑և�问题�q�是�?x��)提供很大的帮助�Q�例如跟�t�框架代码、jdk代码�{�等�Q�对于访问的�q�程�E�序而言�Q�则不太相同�Q�java嘛，�q�好�Q�可以支持远�E�调试，我相信现在的大部分语�a�都支持的�Q�远�E�调试那是相当的重要呀�Q�于是我们就可以在本地调试着�q�程某台服务器上执行时的bug�Q?)�Q�偷着乐吧�?br />
最后一�U�最痛苦的大家最惌���试的场景�Q�就莫过于生产环境了(ji��n)�Q�估计有N多�h都想直接在生产环境中调试�Q�看看生产环境中的问题是怎么产生的，但生产环境嘛�Q�是不太可能拿来调试玩的�Q�而有些时候线下要模拟也不是什么简单的事，说到�q�，又要天马行空的瞎扯下�?ji��n)，记得在云风的blog上以前有写过一���游戏中对于出错场景的记录以�?qi��ng)回攄���功能�Q�这功能听着是相当的帅呀�Q�好�Q����l�回到正题，在自��q��代码�q�没有如此强大的错误记录和回攑֊�能时�Q�也许能做的选择���是在代码中多写一点log.debug�?ji��n)，在生产环境有问题�Ӟ��则打开相应的日志的debug��，然后�l�箋(hu��)靠�h肉分析了(ji��n)�Q�这个时候还是体��C��(ji��n)log.debug的强大作用滴�Q�根据这点可以看出，在代码中�q�是有必要写些合适的log.debug的，除了(ji��n)��Z��(ji��n)自己外，对于其他使用的�h调试bug也是可以�i�予很大的帮助的�?br />
<br />
嗯，没想到稍微扯�?ji��n)下�Q�也写了(ji��n)不少�Q�从�q�稍微写的内容中�Q�其实也能看出，调试可不是闹着玩的事，�l�对需要相当完整的知识体系�Q�这也难怪张银奎的《��Y件调试》写�?ji��n)三�q�_(d��)��而且那么的厚�Q�看来还是值得看看的，:)�Q�小�q�告�Q�大家别在意�?br />
而且�q�里�q�没说到�Q�通常需要调试的时候，多数都是出问题的时候，那么�q�个时候还?sh��)��(x��)面临很大的压力�Q�怎么样在紧急的旉���内还冷静(r��n)的做好�h肉分析的工作�Q�这可是相当的考验抗压能力、技术基本功、逻辑分析能力和学�?f��n)能力的�q�程�Q�想惻I��要能在短旉���内查出问题的原因�Q�通常需要对代码�q�行的场景做出冷�?r��n)的分析�Q�进而需要具备从头到������知识�Q�例如所采用的框架、java包、甚臛_��JVM、操作系�l�、硬�Ӟ��实在不行的话�Q�还得��(f��)时学�?f��n)下�q�些知识�Q�这��h��能在短时间内解决�Q�因此想来想去，���来���觉得如果在面试的时候让面试者现�����试段�E�序貌似�q�是挺靠��q���Q�更有助于全方位的考察�Q�貌似只有很���数的几家公�怼�(x��)�q�么�qԌ��当然�Q�这有客观条件的原因�Q�但要克服貌��g��不是很难�?
