<br />    <li>Don&rsquo;t program and don&rsquo;t know much about evolving system internals, but makes key technical decisions. Often has completely irrelevant and unreal picture what is happening with the system.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 不进行��Y件开发，对系�l�内部知之甚���，但却要做出关键的技术决�{��?font color="#ff0000">对系�l�经常有完全无关和虚�qȝ��映像�Q�不太会(x��)���译�q�句�Q?/font>�?</li>
<br />    <li>Tends to complex, premature and generic solutions when the system is still in infancy and nothing is clear. Applies latest modern buzzword technologies as SOA, MDA, SaaS, Software Factories, etc. which look so beautiful in technical magazines, conferences and CV, but cause unnecessary headache for developers.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 当系�l�仍处于起始阶段�Q�都�q�不明晰的时候，�怼�(x��)做出复杂的，不成熟仅仅通用的决�{�。��用在技术杂志、技术大�?x��)和CV上看��h��如此���妙的现代最新的口号�Q�诸如SOA�Q�MDA�Q�SaaS�Q�Software Factories�{�等�Q�只是给开发�h员带来不必要的头痛�?</li>

<br />    <li>Reduces quality of decisions, which become limited to one perspective; decision making starts lacking diversity, independence and decentralization, which are essential attributes of <a  title="collective intelligence" id="mxv.">collective intelligence</a>.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;军_��仅仅局限在某个角度&nbsp;�Q�降低了决策的质量；最初的军_���~�Z��多样性，独立性和向下兼容�Q�这些都是集体决�{�的本质�?nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </li>
<br />    <li>Creates tension with developers who experience mismatch between grand design and reality. Often continues pushing design decisions until the system becomes overly complex, difficult to change and becomes completely unusable.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 在缺乏大型设计和实现�l�验的开发者之间制造紧张氛围。不断的做出军_���Q�系�l�变得过度复杂，难于改变�Q�和应用�?</li>
<br />    <li>Secures job and justifies high salary - becomes authoritative center for solving business problems without much input from the team.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 有稳定的工作和高薪，成�ؓ(f��)解决业务问题的权威，但却从未融入到团队当中�?</li>
<br />    <li>Causes loss of sense of ownership, motivation and accountability in developers by detaching them from the key architecture decisions.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 把开发�h员排除在关键架构决策之外�Q�让他们�~�Z����d��性和责�Q感�?</li>

    <table width="100%"><tr><td><p><p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font size="4">&nbsp;&nbsp;&nbsp;今天�ȝ��一下这个系�l���Y件��用的�pȝ��架构�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;�q�个软�g使用的mvc框架有点�c�M��于struts�Q�我是在2005�q�开始接触java的，在维护这个系�l���Y件之前��用的mvc框架包括struts和webwork两种�Q�相比较之下�Q�与strtus更�ؓ(f��)�c�M���Q�或�怹�是因为strus中控制类部分也是直接操作request吧�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;�q�个mvc框架自��n的特点大致有�q�么几个�Q?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1.�q�个mvc框架没有使用配置文�g�Q�在webconfig文�g中配�|�有一个��L��的servlet�Q�负责接受页面提交的��h���Q�进行�{发�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ��面提交��h��方式是直接请求这个��L��servlet�Q�在提交��h��到这个servlet的同�Ӟ��提交两个固定的参敎ͼ�分别是class和method参数�Q�通知servlet���请求�{到相应的�c�，�q�调用参��C��的方法�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.��L��servlet调用的类为普通的java�c�，没有�Ҏ(gu��)��的要求，比如struts中要�l�承action父类�Q�方法写法有严格的要求，为静态方法，不允许有�q�回参数�Q�接受的参数也固定，如下�Q?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<font face="Arial">&nbsp;public static void expMethod(HttpServletRequest req,<br />
<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; HttpServletResponse res,<br />
<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RequestHash reh) throws&nbsp;&nbsp;&nbsp;&nbsp; Exception {}</font></font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;因�ؓ(f��)没有使用配置文�g�Q�方法调用结束后�q�回到哪个页面，在该�Ҏ(gu��)��中直接赋��D����面的具体�\径。这样修改�v来有点复杂，需要重新编译类�Q��ƈ且在调试的时候，如果需要找到该��h��调用的页面的具体路径�Q�必���L��到这个类和方法，不如使用配置文�g一目了然�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.获取��面上的参数�Q�这个框架提供两�U�不同的选择�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 框架提供一个Common的对象，该对象封装了对request的部分操作，提供了一�?font face="Arial">RequestHash对象�Q�该对象��Z��个Vector集合�Q�页面表单提交的数据已经���装到该集合中，参数</font>获取方式为，创徏一个字�W�串数组�Q�将需要获取的参数名称赋值到该数�l�中�Q�Common的toData�Ҏ(gu��)���q�回与字�W�串数组相对应的参数��|��如下</font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Common common = new Common(req,res);//req request对象�Q�res为response对象</font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <font face="Arial">String[] keys = {&quot;param1&quot;,&quot;param2&quot;};<br />
<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String[] values = common.toData(reh, keys);</font></font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 此时values数组中，values�?】中的��gؓ(f��)param1表单��|��相应的�ؓ(f��)param2的表单倹{�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 如果需要获取一个数�l���|��request的操作是getParamValues�Ҏ(gu��)���Q�例如表单中的复选框��|��RequestHash对象提供了类��g��request的这个操作�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <font face="Arial">reh.getParameterValues(&quot;params&quot;);</font></font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.为显�C�页面赋��g��使用了Common对象�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a�?nbsp;赋值简单的字符串对象：(x��)<font face="Arial">common.addString(&quot;showParam&quot;, param);</font></font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; �W�一个参��Cؓ(f��)��面获取该参数��g��用的名称�Q�第二个�����对象名称�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; b、一�ơ性赋值多个字�W�串对象�Q?font face="Arial">common.addArray(keys, values);</font></font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 相对应的�Q�keys为页面获取参数值的名称�Q�values为参数的倹{�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; c、赋��g��个复杂的对象�Q�例如自定义对象或者一个List对象�Q?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <font face="Arial">common.addObject(&quot;voname&quot;, vo);</font></font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 用法一致�?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 该框架提供一套通用的js脚本库和一些统一的赋��D��则，例如��d��用户对象名称�Q�子�pȝ��名称和提�C�名�U�ͼ�因此common对象赋��g��提供了一些特�D�的�Ҏ(gu��)���Q�只接受参数的��|��参数名称为已定义名称�Q�因此在为页面赋��g��要注意不要与�pȝ��框架已定义对象名�U�冲�H��?/font></p>
<br /><p><font size="4">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 今天写到�q�里�Q�下一���写写这个mvc框架的页面逻辑�Q�标�{�还有这个脚本库的内容吧�?/font></p></p></td></tr></table>
