<h2 id="u6587_u4EF6/_u76EE_u5F55_u6743_u9650_u8BBE_u7F6E_u547D_u4EE4_uFF1Achmod"><a href="#u6587_u4EF6/_u76EE_u5F55_u6743_u9650_u8BBE_u7F6E_u547D_u4EE4_uFF1Achmod" class="headerlink" title="文件/目录权限设置命令：chmod"></a>文件/目录权限设置命令：chmod</h2><p>这是Linux系统管理员最常用到的命令之一，它用于改变文件或目录的访问权限。该命令有两种用法： </p>
<p>用包含字母和操作符表达式的文字设定法 </p>
<p>其语法格式为：chmod [who] [opt] [mode] 文件/目录名 </p>
<p>其中who表示对象，是以下字母中的一个或组合： </p>
<p>u：表示文件所有者<br>g：表示同组用户<br>o：表示其它用户<br>a：表示所有用户<br>opt则是代表操作，可以为：<br>+：添加某个权限<br>-：取消某个权限<br>=：赋予给定的权限，并取消原有的权限<br>而mode则代表权限：<br>r：可读<br>w：可写<br>x：可执行 </p>
<p>例如：为同组用户增加对文件a.txt的读写权限： </p>
<p>chmod g+rw a.txt </p>
<p>用数字设定法 </p>
<p>而数字设定法则更为简单：chmod [mode] 文件名 </p>
<p>关键是mode的取值，一开始许多初学者会被搞糊涂，其实很简单，我们将rwx看成二进制数，如果有则有1表示，没有则有0表示，那么rwx r-x r- -则可以表示成为： </p>
<p>111 101 100 </p>
<p>再将其每三位转换成为一个十进制数，就是754。 </p>
<p>例如，我们想让a.txt这个文件的权限为： </p>
<p>自己 同组用户 其他用户<br>可读 是 是 是<br>可写 是 是 可执行 </p>
<p>那么，我们先根据上表得到权限串为：rw-rw-r–，那么转换成二进制数就是110 110 100，再每三位转换成为一个十进制数，就得到664，因此我 们执行命令： </p>
<p>chmod 664 a.txt</p>

<h1 id="u547D_u4EE4_u65B9_u5F0F"><a href="#u547D_u4EE4_u65B9_u5F0F" class="headerlink" title="命令方式"></a>命令方式</h1><p>在Shell提示符后输入命令vi，进入vi编辑器，并处于vi的命令方式。此时，从键盘上输入的任何字符都被作为编辑命令来解释，例如，a(append）表示附加命令，i(insert）表示插入命令，x表示删除字符命令等。如果输入的字符不是vi的合法命令，则机器发出“报警声”，光标不移动。另外，在命令方式下输入的字符（即vi命令）并不在屏幕上显示出来，例如，输入i，屏幕上并无变化，但通过执行i命令，编辑器的工作方式却发生变化：由命令方式变为输入方式。 </p>
<h1 id="u8F93_u5165_u65B9_u5F0F"><a href="#u8F93_u5165_u65B9_u5F0F" class="headerlink" title="输入方式"></a>输入方式</h1><p>通过输入vi的插入命令（i）、附加命令（a）、打开命令（o）、替换命令（s）、修改命令(c）或取代命令（r）可以从命令方式进入输入方式。在输入方式下，从键盘上输入的所有字符都被插入到正在编辑的缓冲区中，被当做该文件的正文。进入输入方式后，输入的可见字符都在屏幕上显示出来，而编辑命令不再起作用，仅作为普通字母出现。例如，在命令方式下输入字母i，进到输入方式，然后再输入i，就在屏幕上相应光标处添加一个字母i。 由输入方式回到命令方式的办法是按下Esc键。如果已在命令方式下，那么按下Esc键就会发出“嘟嘟”声。为了确保用户想执行的vi命令是在命令方式下输入的，不妨多按几下Esc键，听到嘟声后再输入命令。</p>
<h1 id="ex_u8F6C_u4E49_u65B9_u5F0F"><a href="#ex_u8F6C_u4E49_u65B9_u5F0F" class="headerlink" title="ex转义方式"></a>ex转义方式</h1><p>vi和ex编辑器的功能是相同的，二者的主要区别是用户界面。在vi中，命令通常是单个字母，如a,x,r等。而在ex中，命令是以Enter；键结束的命令行。vi有一个专门的“转义”命令，可访问很多面向行的ex命令。为使用ex转义方式，可输入一个冒号（:）。作为ex命令提示符，冒号出现在状态行（通常在屏幕最下一行）。按下中断键（通常是Del键），可终止正在执行的命令。多数文件管理命令都是在ex转义方式下执行的（例如，读取文件，把编辑缓冲区的内容写到文件中等）。转义命令执行后，自动回到命令方式。例如： :1,$s/I/i/g 按Enter键</p>

<p>标量值函数:返回类型只能是基类型，其返回值类型为除TEXT、NTEXT 、IMAGE、CURSOR、 TIMESTAMP 和TABLE 类型外的其它数据类型。函数体语句定义在BEGIN-END语句内，其中包含了可以返回值的Transact-SQL 命令。调用返回表的 SQL Server 内置函数时，必须将前缀 :: 添加至函数名：<br>SELECT * FROM ::fn_helpcollations()</p>
<p>存储过程:可包含程序流、逻辑以及对数据库的查询。它们可以接受参数、输出参数、返回单个或多个结果集以及返回值。</p>
<p>函数与存储过程本质上没区别。只是函数有如：只能返回一个变量的限制。而存储过程可以返回多个。而函数是可以嵌入在sql中使用的,可以在select中调用，而存储过程不行。执行的本质都一样。函数限制比较多，比如不能用临时表，只能用表变量．还有一些函数都不可用等等．而存储过程的限制相对就比较少<br><a href="http://knowsky.com/534162.html" target="_blank" rel="external">转载地址</a></p>

<li>被合并的子web项目packaging属性必须是war</li>
<li>被合并的子web项目，必须在主项目中添加依赖关系。</li>
<li>被合并的子web项目中，如果没有web.xml，则需要在pom.xml中声明</li>
<li>在web项目主模块中的java build path 中添加子web项目的依赖，就可以直接调用子项目的方法咯(记得避免循环依赖哦)</li>
<li>被合并的子web项目中的web.xml你可以选择性的放入合并内容当中(可以看情况需要进行合并)</li>
<li>配置文件继承相同的继承策略用于为 POM 本身。<br>只要配置好以上内容，该多个模块的maven项目的主web模块就可以放到tomcat中运行起来啦。</li>
