Guice在注入的构造函数参数上忽略@Nullable [英] Guice ignoring @Nullable on injected constructor parameter

问题描述

我正在使用Guice（v 3.0）并且有一个值被注入到构造函数中。这个值可以为null，所以我在构造函数中使用@Nullable（来自javax.annotations）注释了该参数。

I'm using Guice (v 3.0) and have a value that is being injected into a constructor. This value can be null, so I have annotated the parameter in the constructor with @Nullable (from javax.annotations).

public MyClass(Parameter1 p1, @Nullable Parameter2 p2) {
}

然而，Guice在初始化课程时抱怨提供错误：

However, Guice is complaining with provision errors when it comes to initialise the class:

parameter 2 of com.abc.MyClass.<init>() is not @Nullable

我不明白为什么这不起作用，还有什么我需要做的吗？

I don't understand why this is not working, is there something else I need to do?
