在方法參數中使用 NotNull Annotation - Using NotNull Annotation in method argument

問題：

I just started using the @NotNull annotation with Java 8 and getting some unexpected results.我剛開始在 Java 8 中使用@NotNull註釋並得到一些意想不到的結果。

I have a method like this:我有一個這樣的方法：

public List<Found> findStuff(@NotNull List<Searching> searchingList) {
    ... code here ...
}

I wrote a JUnit test passing in the null value for the argument searchingList.我編寫了一個 JUnit 測試，傳入參數 searchList 的空值。 I was expecting some type of error to happen but it went through as though the annotation was not there.我原以爲會發生某種類型的錯誤，但結果好像註釋不存在一樣。 Is this expected behavior?這是預期的行爲嗎？ From what I understood, this was to allow you to skip writing the boilerplate null check code.據我瞭解，這是爲了讓您跳過編寫樣板空檢查代碼。

An explanation of what exactly @NotNull is supposed to do would be greatly appreciated.對@NotNull 究竟應該做什麼的解釋將不勝感激。
