load-on-startup
1、元素标记表示容器在启动时是否加载该Servlet ，实例化并调用init方法。

2、load-on-startup的值必须是整数，表示servlet加载的顺序，当值为0或者大于0时，表示容器在应用启动时就加载并初始化该servlet。

3、当值小于0或者不指定时，表示容器在该Servlet被访问时才会被加载。

现象：设置WAS的SERVLET参数问题当用户在使用WebSphere Studio V5或者Retional Application Studio V6开发Web应用的时候，启用启动时加载的默认参数为load-on-startup=-1。但是当用户把应用部署到WAS V6.0.1.2以下的版本中，会发现在应用启动的时候初始化方法Init()没有被自动执行，而只有显示地调用Servlet的

        load-on-startup 元素在web应用启动的时候指定了servlet被加载的顺序，它的值必须是一个整数。如果它的值是一个负整数或是这个元素不存在，那么容器会在该servlet被调用的时候，加载这个servlet 。如果值是正整数或零，容器在配置的时候就加载并初始化这个servlet，容器必须保证值小的先被加载。如果值相等，容器可以自动选择先加载谁。

Servlet是单例对象 整个tomcat运行阶段只有一个对象，默认情况第一次访问的时候调用无参数的构造器创建对象,如果在web.xml文件中配置类标签&lt;load-on-startup&gt; 该对象的Servlet会随着tomcat的启动创建。（或在注解，tomcat启动项目的时候会自动扫描所有Servlet文件，有注册会把注解和类关联记录loadOnStartup该servlet对象随t...

在servlet的配置当中，&lt;load-on-startup&gt;5&lt;/load-on-startup&gt;的含义是：标记容器是否在启动的时候就加载这个servlet。当值为0或者大于0时，表示容器在应用启动时就加载这个servlet；当是一个负数时或者没有指定时，则指示容器在该servlet被选择时才加载。正数的值越小，启动该servlet的优先级越高。只有当 @WebServl...
Servlet 启动时加载＜load-on-startup＞

在 Servlet 中启动时加载。当我们在 servlet 上启用 <load-on-startup> 时，Servlet 容器会在服务器启动期间或 Web 应用程序部署期间创建我们的 Servlet 类对象。这称为 servlet 的预实例化和预初始化。 servlet 中启动时加载的示例：- <web-app> <servlet> <servlet-name>date</servlet-name> <se
