将grails集成到我的Java EE应用程序中

Question

I have a simple Java EE application using Servlets and JSP.

Now I want to develop new functionality using Grails within the same application not a new application. Can I add Grails to my existing application?

Answer 1

You'll have more luck the other way round - create a new Grails application, put your existing servlets into src/java , then run grails install-templates and edit the template web.xml to add your <servlet> and <servlet-mapping> tags to that. But note that Grails installs a number of filters that intercept all urls, and these may adversely affect your servlets. You'll have to try it and see what breaks...

Answer 2

It very well depends on the framework ur currently using. I'd try with adding grails' lib subdirectory to the project classpath.
