使用Spring从压缩文件中提供静态资源

Question

Is it possible to serve static resources from within a compressed file using Spring MVC? Something like this .

I have some data packaged into individual JSON files (eg 123.json, 1634.json, etc.) and and currently serving them via

<mvc:resources mapping="/resources/**" location="/resources/" />

The files are under .../resources/dataFiles/ . So a user can go to http://mywebsite.com/resources/dataFiles/123.json to retrieve the data for entity 123.

However, I have ~10,000 JSON files. It would be great if I could compress them under one file ( .../resources/dataFiles/entities.zip ) and tell Spring to serve the individual JSON files from within the compressed file.

So the user would still go to http://mywebsite.com/resources/dataFiles/123.json but the only file under .../resources/dataFiles/ is entities.zip.

I'm using Tomcat 7.0 if this question is outside the scope of the MVC framework.

I'm not sure if there's a Spring out-of-the-box component that does that, but you can create an independent Servlet to handle the incoming requests for static resources, then this servlet would parse the file name, and dynamically read from the zipped file the correct Zip Entry and return the content to the OutputStream of the Response. Take a look at:
