Extract/See content of a specific file inside a .war file

问题

I am trying to view the content of a file ( in linux )that is inside a .war file without having to extract the war file. For example inside the war file i am trying to see the content of a file called aa.txt and which is under /path/here/ inside the war file.

回答1:

jar has x option for that:

$ jar -help 2>&1 | grep extract
    -x  extract named (or all) files from archive

Let's try it:

$ jar tvf target/my.war | grep test-data

$ jar xvf target/my.war WEB-INF/classes/test/spring/test-data.properties
 inflated: WEB-INF/classes/test/spring/test-data.properties
$ ls -l WEB-INF/classes/test/spring/test-data.properties
