ServletConfig對象

    servlet配置了初始化參數後,web容器在建立servlet實例對象時,會自動將這些初始化參數封裝到ServletConfig對象中,並在調用servlet的init方法時,將ServletConfig對象傳遞給servlethtml

  <servlet>java

    <servlet-name></servlet-name>web

    <servlet-class></servlet-class>api

    <init-param>this

        <param-name></param-name>spa

        <param-value></param-value>code

    </init-param>htm

  </servlet>對象

  在實際開發中 直接能夠經過getServletConfig()獲得ServletConfig對象

 

String getInitParameter(String name)
Returns a String containing the value of the named initialization parameter, or null if the parameter does not exist.
Enumeration getInitParameterNames()
Returns the names of the servlet's initialization parameters as an Enumeration of String objects, or an empty Enumeration if the servlet has no initialization parameters.
ServletContext getServletContext()
Returns a reference to the ServletContext in which the caller is executing.
String getServletName() Returns the name of this servlet instance.
