<p>笔者在第一次使用eclispe 3.7即indigo这个版本的时候，便发现一个小小的不快：平时在不知道某个方法怎么写的时候会按下Alt +/去获取eclipse给出的提示。但是在3.7这个版本却不好用，得到的是eclipse自动帮你选择一个他认为最合适的方法或者变量等等，帮你补全，而不是原来的显示所有可供选择的，让你来选择。</p>
|
||
<p>纠结了很久，期间尝试过使用网上说的修改Content Assist。将之前默认的 .后面加上ABCD…abcd…所有52个字符。并且 把联想的时间从系统默认的200ms提高到50ms。但是经过修改之后，eclipse变得和visual studio 一样，你每输入一个字符，系统就会进行一次提示。不过我发现这种情况下eclipse占用的CPU、内存资源变多了，在我的笔记本有时候还会变得顿卡。这不是最好的办法。</p>
|
||
<blockquote>
|
||
<p>前几天吧，我才发现这个问题的症结所在。原来是eclipse官方的快捷键方式改变了。其实以前Alt+/那个联想一直在，只是在3.7版本里面这个快捷键变成了自动补全（即系统自动选择一个最合适的进行补充）。我们需要做的就是依次打开Windows——preferences——General——Keys。找到<strong>Content Assist</strong>这一项，这一项系统默认的是Alt+Space。这里我们把它改成<strong>Alt+/</strong></p>

<p>好不容易，求我老汉给了1000，还要把自己原来的镜头卖掉，还要一个月省吃俭用500块钱，才可以买下这个镜头。今天从南充过来，下火车就去把镜头买了￥2130.还要吧比我想象中的贵了几十块钱。不过买了镜头，我的兜里就只剩下20多块钱了。哎，所以必须得尽快卖掉那个原有的套头。</p>
|
||
<p>猜到了很多人看到我买了镜头就会觉得我很有钱，我真的有钱吗？我难道还不清楚，随便你们怎么说吧！面对流言蜚语我有什么办法。我只能套用那句俗话，走自己的路，让别人说去吧！</p>
|
||
<p>还是说说镜头，大光圈确实效果很不错，镜头很厚实，不够就是对焦的时候声音有点大！马达吱吱地想!!</p>
|
||
<p>镜头没有防抖功能，希望使用的时候不会出现什么问题吧！下面上图一张</p>

<p>也许是今天上课听到其他人讲人家去腾讯面试怎么怎么样，我心里还是有很大的震动。我不再想学android了，虽然老师叫我负责这一块工作，但是我感觉我在学习的过程中发现android的代码逻辑和我平时接触的java EE的逻辑还是有一些区别。我真的还是喜欢搞我的网站。这些我都比较了解。我也喜欢那些新鲜的事物，因为我喜欢他。虽然就在今天上午之前，我还是很想把Android尽快学好。但是原谅我吧，明年我就去面试了，在这短短一年的时间里面请允许我学习我最喜欢的东西吧，这样我想我胜利的机会才会更大。</p>
|
||
<p>况且，我觉得Web App应该是未来的王者，看看Chrome OS,虽然现在Android 还不推荐使用Web App ,但是我大胆预测一下，未来三年内Android 将允许使用Web App.而且Windows 8将来也支持使用javascript +html 5进行程序开发。这些都是学习javascript的好处吧。而且我自己也有javascript 的底子啊，经过暑假一个多月的奋斗，我觉得我的javascript能力提升了不少！</p>
|
||
<p>看看Java EE那么多好用的框架，看看 Nosql是多么地吸引人，看看node.js是多么的新潮，还有很多很多好的东西！</p>
|
||
<p>从现在开始，我就搞Java EE了！</p>
|
||
<p>加油！</p>

<p>在我看来积极性可能比能力更加重要，能力可以努力一点一点提升，但是积极性却是一个人内心意识的反应。我们通常我们感兴趣的事情很有积极性，充满斗志。但是有那么一部分人，他之前的行为让你觉得他对这个事情满怀激情，但是一旦他到达一个一个安定、稳定的环境，即使是他自己感兴趣的事情，他也变得懒惰了。难道他们仅仅是因为虚荣心吗？</p>
|
||
<p>最近在帮助老师做一个android项目，由于我是高一级的学生，于是老师叫我负责这个android团队，带领低一级的同学一起参与界面设计、问题讨论、代码编写。但是通过开学这几周下来，我发现这个leader不太好当。我一个人做了几个人的事情。而且我还发现，编程的孩子只喜欢编程，他们不想参与讨论，不想参与草图的制作，心里面想的是，一拿到这个程序立刻开始写代码。界面设计的同学也不愿意开会讨论。设计出来的结果也不能让人满意，没有一点规范可讲。甚至我们最初梦寐以求的进入实验室，他们现在都开始变得不那么渴求，或者说也许只是对实验室名称上的渴求。一旦进入实验室，他们便变得不那么积极了。所有的这一切都让我有一个想法，这些学弟、学妹们怎么了，怎么变得一届不如一届了。</p>
|
||
<p>我希望他们对每一项新的任务都已积极的心态来对待，其实每一种技能都是你的本钱，我现在体会得越来越深了。开发一个软件，不仅仅是代码、代码虽然重要，但是如果没有软件工程、没有市场营销、没有良好的用户体验设计，其实这个软件根本不能用，即使你的代码写的再好、即使你的算法再优良。以积极的心态去面对每一项任务，把他们当做一个个新的挑战去完成，虽然过程中你可能会很累、很迷茫、很沮丧，但是坚持到最后，你才发现你学到了很多东西，不仅仅是编写代码。</p>
|
||
<p>积极、乐观的态度，还可以给你的老师、你的上司留下好的印象。最重要的是积极这种生活态度很好！说不出的好。</p>

<p>之所以会将之前的顶级域名博客，弃用，而转而使用这个博客，其实我算是不得已而为之。</p>
|
||
<p>也许就是舍不得再花钱在这里面吧，想想自己最初的打算，用写博客挣的广告费用，来购买空间，可实际上呢？</p>
|
||
<p>哎，还是省省吧。</p>
|
||
<p>虽然橡皮泥一直没有把我的空间给我停掉，但是我自己也过意不去啊。毕竟空间他也是花钱买的啊！</p>
|
||
<p>综上所述，所以我还是决定了，就用这个新浪的试试看吧！</p>
|
||
<p>加油新浪，加油Junv!</p>
|
||
<p>争取今天或者明天写一篇新的博客吧！</p>

<p>昨天看了一些网上的tomcat数据库连接池配置的东西，但是一直没配好，主要原因是网上的文章几乎没有争对tomcat 7进行配置的，而且针对SQL SERVER的也不多，今天上午看了官方的文档，花了一上午时间终于配置好了数据库连接池，这里发给大家看看，如果有什么疑问就留言吧。</p>
|
||
</blockquote>
|
||
<p>首先我们需要向项目中导入tomcat-dbcp.jar 、servlet-ap.jar和sql server的驱动sqljdbc4.jar 包到 web-inf 文件夹下的lib目录 。</p>
|
||
<p>然后增加context.xml</p>
|
||
<p>这里有两种方法，第一种是在tomcat程序目录下面的conf/context.xml里面修改，这里修改之后所有的程序都将都将覆盖数据库连接池，但是这种方法不够灵活。这里我们选择第二种方法 在项目的Web-content/meta-inf 目录下创建一个context.xml文件，在里面添加如下内容：</p>
|
||
<figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line"></span><br></pre></td></tr></table></figure>
|
||
|
||
<p>这里需要修改的是 将所有的SYSDEMO改为你自己的使用的数据库的名称</p>
|
||
<p>将driverClassName改为你所使用数据库的驱动，这里是SQL SERVER的驱动。</p>
|
||
<p>将url改为jdbc链接该数据库的地址,这里是SQL SERVER的地址，</p>
|
||
<p>将username 、password改为你自己数据库用户名和密码</p>
|
||
<p>maxActive=”100″ maxIdle=”30″ maxWait=”10000″</p>
|
||
<p>可以将这三个参数进行修改，</p>
|
||
<p>第一个是最大活动的连接数</p>
|
||
<p>第二个是最大的未连接数</p>
|
||
<p>第三个是最长的等待时间，单位是毫秒</p>
|
||
<p>然后再修改项目的webContent/web-inf/web.xml文件</p>
|
||
<p>添加如下内容:</p>
|
||
<figure class="highlight xml"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line">MySQL Test App</span><br><span class="line"> </span><br><span class="line"> DB Connection </span><br><span class="line"> jdbc/blog </span><br><span class="line"> javax.sql.DataSource </span><br><span class="line"> Container </span><br><span class="line"> </span><br></pre></td></tr></table></figure>
|
||
|
||
<p>这里必须要改的是: jdbc/SYSDEMO</p>
|
||
<p>改为 jdbc/你自己的数据库</p>
|
||
<p>好了然后就可以使用了。</p>
|
||

<p>将 DataSource ds = (DataSource)envContext.lookup(“jdbc/SYSDEMO”);</p>
|

<p>“jdbc/SYSDEMO” 的sysdemo改为你前面使用的数据库的名称即可。</p>

<p>好了。大功告成。</p>

<p>最近看到很多朋友都留言回复很开心，我也很高兴，自己做的这样一个小程序可以帮到你们。上篇文章详细讲了如果实现android端的代码，很多朋友都在问s服务器端servlet源代码，这里就贴出来给大家吧，但是最近很忙，就先暂时不详细解释了。</p>

<blockquote>
|
||
<p>这里说明一点，这个程序是使用了Apache Commons 的一个上传文件的开源组件叫做FileUpload,用的包是commons-fileupload-1.2.2.jar。其他的就不多说了，如果你直接粘贴使用下面代码，请你一定要导入这个包。</p>

<p>最近帮老师做一个拍照上传的小android 应用。以前虽然看过这方面的东西，但是没有真正做过东西出来，这次老师要求在一个星期左右做出来，其实还是给了我不少压力，于是自己一边学习，一边写代码，同时在望山找了大量的东西，最初都没有解决这个问题。后面才慢慢解决这些问题。</p>

<p>执行完这个方法，我们通过bitmap对象将拍照所得已经显示在程序里面了，然后之所以将其保存为文件，是为了上传的方便。</p>
|

<p>然后下面是一个上传的图片的方法，大概就是将图片构建成流发送到是、服务器端，这个代码是使用的网上一个前辈的代码，这里不知道他的地址了，但是还是说明一下吧，并表示感谢。</p>

<p>不知道各位同学使用svn吗？简单说SVN是一个代码版本管理软件，可以让不同的人更新和同步代码，并对代码进行版本管理。现在google code 里面这么多开源项目，都是可以去用SVN checkout 下载下来源代码的，不知道各位有没有尝试呢？</p>
|
||
<p>最近在做一个小小的项目的时候用到了SVN，但是当时也发现一个问题，就是tortoise SVN 不能checkout google code 里面的代码。当时用谷歌找了找，可是没发现解决的办法，今天又看到我比较喜欢的google制作的一本电子书——<a target="_blank" rel="noopener" href="http://code.google.com/p/20thingsilearned/">20thingsilearned</a>，里面包含了很多HTML 5和CSS 3特性，而且他还说一个开源项目，说明我们免费的去下载源代码来研究它里面很酷炫的东西。当然也面对了同样的问题，不能checkout.</p>
|
||
<blockquote>
|
||
<h1 id="Non-members-may-check-out-a-read-only-working-copy-anonymously-over-HTTP"><a href="#Non-members-may-check-out-a-read-only-working-copy-anonymously-over-HTTP" class="headerlink" title="Non-members may check out a read-only working copy anonymously over HTTP."></a>Non-members may check out a read-only working copy anonymously over HTTP.</h1><p> svn checkout <em><strong>http</strong></em>://20thingsilearned.googlecode.com/svn/trunk/ 20thingsilearned-read-only</p>
|
||
</blockquote>
|
||
<p>这是谷歌官方的代码，大概的意思是所有的匿名用户都可以使用下面这个地址进行匿名checkout ,即是不用登陆。不过我试着新建一个文件件，右键，选中tortoise SVN的checkout 选项，还是不行，最终在<a target="_blank" rel="noopener" href="http://superuser.com/questions/44409/cant-checkout-source-from-google-code">国外一个网站</a>找到了解决的办法，即是正确的地址是<em><strong>http</strong></em>://20thingsilearned.googlecode.com/svn/trunk/ 去掉后面的那些东西，因为那些东西是为CLI 用户使用的（什么是CLI用户我也不太清楚）.总之你使用去掉后面那一块的地址就可以checkout啦。</p>
|
||
<p><a href="/images/2011/06/xxx.jpg"><img src="/images/2011/06/xxx.jpg" title="xxx"></a></p>
|
||
<p>还有如果你是项目发布者checkout不能弹出提示框要求你输入密码的话，请先这样做，请先选中tortoiseSVN里面的import选项，在里面弹出你的SVN地址，比如我的项目的地址是<a target="_blank" rel="noopener" href="https://moland.googlecode.com/svn/trunk/">https://moland.googlecode.com/svn/trunk/</a> moland –username wahyd4。这个回跟上你的项目名称和用户名的。然后就会提示你输入用户名和SVN密码，这个密码是项目里面生成的SNV密码而不是google账户密码哦。然后就会自动import了，然后你就可可以顺利checkout l了、。。</p>

<li>软件包含的设计元素更加丰富，包含10个类别，而且支持将所有元素都变为速写设计的样式，看起来更加像用笔画的（我个人这样粗俗地认为）</li>
|
||
<li>对于每个元素可以细节调节的操作和修改更加丰富。</li>
|
||
<li>支持多窗口设计</li>
|
||
<li>支持想设计导出为PNG、PDF</li>
|
||
<li>针对移动设备做了很多很好的工作。</li>
|
||
<li>支持将设计导出为html、css、flex文件等</li>
|
||
<li>让设计人员使用起来效率更高吧。</li>
|
||
</ul>

<p>下面是我刚才花大概15分钟设计的一款一个简单的界面：</p>
|
||
<p><a href="/images/2011/06/newMockup.png"><img src="/images/2011/06/newMockup.png" title="newMockup"></a>因此大家可以知道，这款软件的设计效率的确不是吹的，虽然这个界面很简单，不过我个人觉得还是很不错啦。</p>
|
||
<p>当然既然有这么多优点，所有它也就理所当然是一款商业软件。目前<a target="_blank" rel="noopener" href="http://balsamiq.com/buy">购买这个软件</a>需要$79美元，才可以获得完整的功能，当然还可以团队购买，会稍微便宜一些。</p>

<p><del>不过对于中国的同学来说，这么贵的软件购买还是比较不太现实。因此还好它有这样一个比较可行的免费获得软件的方式：如果你是技术/软件博客作者或者记者，那么你写一篇博客来进行推广和宣传他们的这款软件也是可以的。因此我便选择了这种方式。</del></p>
|
||
<p>最新消息：昨天这个软件商发给我一封邮件，说他们已经不再提供给博客作者的免费的授权了。看来这种方法是得不到了，大家还是去用免费的软件吧。。</p>

|
||
<p>当然它还有免费的在线版本供大家使用，或者下载试用版本！</p>
|
||
<p>希望各位都去试试吧！</p>
