RequestParam

[satish kumarkkkk]

"@RequestParam also comes in handy when you compile your Java code without debugging information compiled in. In that circumstance, the name of the method parameter is lost and so there’s no way to bind the query parameter to the method parameter by convention. For that reason, it’s probably best to always use @RequestParam and not rely too heavily on the convention."

Above is text from Spring in Action from SpringMVC chapter. Can somebody explain me above? I didn't understand what do we mean by " without debugging information compiled in. In that circumstance, the name of the method parameter is lost "

Thanks

Sure, when you compile your Java code through the JVM, the compiler can add meta-information such as line numbers, the source file name, variable attributes. When we compile through an IDE, usually these settings are turned on because we want to use the IDE debugger. When we go to production, we want to get a performance improvement by not compiling with this additional meta-information.
