禁止 javac 警告“...是内部专有 API，可能会在未来版本中删除"； [英] Suppress javac warning "...is internal proprietary API and may be removed in a future release"

问题描述

当我使用 JDK 1.7.0 在 OS X 上编译 Spring JDBC 源代码时，我收到此警告:

When I compile the Spring JDBC source on OS X with JDK 1.7.0, I get this warning:

warning: CachedRowSetImpl is internal proprietary API and may be removed in a future release

如何在编译期间抑制警告消息?

How do I suppress the warning message during a compile?

我已经知道并使用了 Java 的 @SuppressWarning 注释.我正在寻找它的具体用途来抑制我所描述的警告.

I already know and use Java's @SuppressWarning annotations. I'm looking for the specific use of this to suppress the warning I've described.

我的问题是，在这行代码中:

My question specifically is, in this line of code:

@SuppressWarnings("valuegoeshere")

valuegoeshere"应该替换成什么?

what should "valuegoeshere" be replaced with?

人们，我知道最好避免导致警告的代码.通常这就是我的方法.但是，我正在此处编译我不想重写的第三方代码.我只是想添加正确的注释来抑制警告，这样我实际上可以做些什么的警告就不会被埋没.

People, I know that it is best to avoid the code that leads to the warning. And usually that would be my approach. However I'm compiling third-party code here which I don't want to rewrite. I just want to add the correct annotation to suppress the warning, so that warnings I can actually do something about don't get buried.

推荐答案

这个特别警告 无法抑制.至少不是正式的.

This particular warning cannot be suppressed. At least not officially.

关于专有 API 的警告意味着您不应该使用导致警告的 API.太阳不支持此类 API 和警告将不会被抑制.

The warning about proprietary API means that you should not use the API which causes the warning. Sun does not support such API and the warning will not be suppressible.

如果你特别确定，你可以使用高度未公开的javac -XDignore.symbol.file 标志，它将针对 Sun 的内部 rt.jar 而不是面向公众的符号文件 ct.sym 编译您的程序.rt.jar 不会产生此警告.

If you're particularly determined, you can use the highly undocumented javac -XDignore.symbol.file flag which will compile your program against Sun's internal rt.jar rather than the public-facing symbol file ct.sym. rt.jar doesn't produce this warning.
