<h1><center>servlet的init()方法启动</h1>
<p><em>2015-12-24 by damon</em></p>
<hr />
<p>如果要想让 servlet 的 init () 方法在服务器启动 时就被执行，则需要在 web.xml 中相应的 servlet 下配置;</p>
<pre><code><servlet>
<servlet-name>test</servlet-name>
<servlet-class>com.damon.test.MyServlet</servlet-class>
<load-on-startup>-1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>test</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</code></pre>
<p>即将： <load-on-startup>1</load-on-startup>设置为正整数（包括0）</p>
<p>这样此servlet就会在服务器启动时执行了。(注意：如果设置为负整数，则不会在启动服务器时执行)</p>
<p>如果不配置，启动服务器时也不会执行，而要等此servlet被调用时才会被执行。 </p>
