问题 Even if it is not possible to use proguard for an entire grails app would it be possible to just use it for the src/java folder? 回答1: I don't know either Proguard or Grails in depth, but I do know that: Grails uses Groovy Groovy compiles down to bytecode Proguard operates on bytecode (not source code) Thus my intuition is yes, ProGuard can shrink/obfuscate grails apps. Your question asks about using ProGuard on the src/java folder. It's important to understand that ProGuard operates on .class

问题 One can use things annotations like: @Secured(['ROLE_ADMIN']) on an actions or on an entire class (seems to work fine), to apply the security control provided by spring security core. Is there a way to apply security to the hidden scaffolded actions, without applying the security constraint to the whole class? I want to use one security constraint for some actions, and a different one for the hidden scaffolded actions. NOTE: if this isn't immediately do-able/answerable, please disregard, as I

问题 Say I wanted to run a Grails (2.3+) app with an extra " -Djava.fizz.buzz=3 " JVM arg. Is it as simple as: grails run-app -Djava.fizz.buzz=3 Or is there special config (say, in BuildConfig.groovy ) that would need to take place? 回答1: The answer to your question is yes, that will work. JVM args work a bit differently. Both are in the docs about the command line. 回答2: That should work. And to have access to the arg you just created, you may call System.properties[] anywhere in your code: if
