Spring Assert.java add support

Assert.java add support

like this:

int a = .......;
Assert.state(a > 0, () -> new RuntimeException("must > 0"));

public static void state(boolean expression, Supplier<RuntimeException> exceptionSupplier) {
    if (!expression) {
        throw exceptionSupplier.get();
    }
}

Comment From: jhoeller

Assert.state is really meant to throw an IllegalStateException, hence the name of the method. In general, we should rather refrain from adding further methods to Assert which is primarily meant as a utility for internal use within the framework.

If you'd like to have such a method, you should rather add it to a custom Assert class in your own codebase instead.
