How can I include a .js file to all jsp pages of my project without editing it?

该文件应在运行时动态地包含在所有jsp页面中

You can do the following:

<jsp-config>
   <jsp-property-group>     
     <url-pattern>*.jsp</url-pattern>
     <el-ignored>false</el-ignored>
     <scripting-invalid>false</scripting-invalid>
     <is-xml>false</is-xml>
     <include-prelude>/javascript.jsp</include-prelude>
   </jsp-property-group>
 </jsp-config>

And include your JS file in javascript.jsp. I haven't tried if directly telling include-prelude to include the JS actually works or not, worth a try.
