Web.xml Learning (2) _context-param

The 5.context-param element is used to set the environment parameter (context) of the Web site, which contains two child elements: Param-name and Param-value.

<param-name> parameter name </param-name> Set context Name

<param-value> value </param-value> Setting the value of the context name

Example:

<context-param>

<param-name>param_name</param-name>

<param-value>param_value</param-value>

</context-param>

The parameters that are set in the JSP Web page can be obtained by using the following methods: ${initparam.param_name}

The following methods can be used in the servlet to obtain: String Param_name=getservletcontext (). Getinitparamter ("Param_name");

<!--context-param element is used to set the environment parameter (context) of the Web site, which contains two child elements: Param-name and param-value., such as spring's typical configuration-->
