Struts2 reads the properties file of the custom configuration

Some custom configurations are always used on the website. I put them in a properties file, such as config. properties this file is placed with struts. in the same XML folder, here I am under SRC.

1. Create a new tool class propertiesutil, and define a public static java. util. properties Class Object PPs in it

2. Create a listener class webconfiglistener and implement the servletcontextlistener interface.

Public void contextinitialized (servletcontextevent arg0 ){

Propertiesutil. PPS = new properties ();

Try {

String Path = (getclass (). getclassloader (). getresource (""). touri (). getpath ();

Fileinputstream FCM = new fileinputstream (path + "config. properties ");

Propertiesutil. PPS. Load (FCM );

} Catch (exception e ){

E. printstacktrace ();

}

}

3. Add webconfiglistener in Web. xml

<Listener>

<Listener-class> com. phonesale. Common. webconfiglistener </listener-class>

</Listener>

4. InProgramUse: propertiesutil. PPS. getproperty (key );
