Hi,
I've successfully used round advice to intercept input parameter for a method.
However, it seems constructor does not work for me. Here're my test: (It's in scala, but should be easy to understand)
class MyObjectTest extends FlatSpecLike with Matchers {
"MyObjectAspect" should "work" in {
val t = new MyObject("leon")
val result = t.talk()
println(result)
result should be("LEON")
}
}
class MyObject(text: String) {
def talk(): String = {
println("MyObject " + text)
text
}
}
@Aspect
class MyObjectAspect {
@Around(value = "execution (com.leon.aop.MyObject.new(..))")
def constructCP(jp: ProceedingJoinPoint): Object = {
try {
println("Start...")
val args = jp.getArgs
args(0) = args(0).toString.toUpperCase
jp.proceed(args)
} finally {
println("End...")
}
}
}
output:
Start...
End...
MyObject leon
leon
"[leon]" was not equal to "[LEON]"

Anything wrong?
Thanks
