<div class="block">
<span>这个类是执行命名操作的起始上下文。</span>
<p> <span>所有命名操作都与上下文相关。</span> <span>初始上下文实现了Context接口，并提供了解析名称的起点。</span> </p>
<p> <span><a name="ENVIRONMENT"></a>当<a name="ENVIRONMENT">构建</a>初始上下文时，将使用传递给构造函数的环境参数中定义的属性和任何<a href="Context.html#RESOURCEFILES">application resource files对其环境进行初始化</a> 。</span> <span>另外，少量的标准JNDI属性可以被指定为系统属性或applet参数（通过使用<a href="../../javax/naming/Context.html#APPLET"><code>Context.APPLET</code></a> ）。</span> <span>这些特殊属性列在<a href="Context.html#field_detail"><tt>Context</tt></a>和<a href="ldap/LdapContext.html#field_detail"><tt>LdapContext</tt></a>接口文档的字段详细信息部分。</span> </p>
<p> <span>JNDI通过合并来自以下两个来源的值来确定每个属性的值：</span> </p>
<ol>
<li> <span>从构造函数的环境参数和（适用的属性）属性的第一次出现的applet参数和系统属性。</span> </li>
<li> <span>应用程序资源文件（ <tt>jndi.properties</tt> ）。</span> </li>
</ol>
<span>对于在这两个来源中找到的每个属性，或在多个应用程序资源文件中，属性的值如下所示。</span>
<span>如果属性是指定JNDI工厂列表的标准JNDI属性之一（请参阅<a href="Context.html#LISTPROPS"><tt>Context</tt></a> ），则所有值都将连接到单个冒号分隔列表中。</span>
<span>对于其他属性，仅使用第一个找到的值。</span>
<p> <span>初始上下文实现在运行时确定。</span> <span>默认策略使用环境属性“ <a href="../../javax/naming/Context.html#INITIAL_CONTEXT_FACTORY"><code>java.naming.factory.initial</code></a> ”，其中包含初始上下文工厂的类名。</span> <span>解决URL字符串时会出现此策略的一个例外，如下所述。</span> </p>
<p> <span>当一个URL字符串（形式<em>一个scheme_id</em>的<tt><em>String：rest_of_name）</em></tt>作为名称参数传递给任何方法，一个URL上下文工厂处理该方案的定位和用于解析URL。</span> <span>如果没有找到这样的工厂，则使用由<tt>"java.naming.factory.initial"指定</tt>的初始上下文。</span> <span>类似地，当第一个组件是URL字符串的<tt>CompositeName</tt>对象作为name参数传递给任何方法时，将定位一个URL上下文工厂，并用于解析名字组件。</span> <span>有关URL上下文工厂位置的描述，请参阅<a href="../../javax/naming/spi/NamingManager.html#getURLContext-java.lang.String-java.util.Hashtable-"><code><tt>NamingManager.getURLContext()</tt></code></a> 。</span> </p>
<p> <span>定位初始上下文和URL上下文工厂的默认策略可以通过调用<tt>NamingManager.setInitialContextFactoryBuilder()</tt>来<tt>覆盖</tt> 。</span> </p>
<p> <span>当初始上下文无法实例化时抛出NoInitialContextException。</span> <span>在与InitialContext的任何交互期间都可以抛出此异常，不仅在构建InitialContext时。</span> <span>例如，初始上下文的实现可能只有在实际方法被调用时才可能懒惰地检索上下文。</span> <span>应用程序不应该依赖于何时确定初始上下文的存在。</span> </p>
<p> <span>当环境属性“java.naming.factory.initial”不为空时，InitialContext构造函数将尝试创建其中指定的初始上下文。</span> <span>那时候，如果遇到问题，最初的上下文工厂可能会引发异常。</span> <span>然而，它是提供者实现相关的，当它验证并向初始上下文的用户指示任何环境属性或连接相关的问题。</span> <span>它可以懒惰地进行延迟，直到在上下文中执行操作，或者在构建上下文时急切地。</span> </p>
<p> <span>InitialContext实例与多线程的并发访问不同步。</span> <span>每个处理不同InitialContext实例的多个线程不需要同步。</span> <span>需要同时访问单个InitialContext实例的线程应在其间同步并提供必要的锁定。</span> </p>
