java - 将 jre 从 8u201 切换到 8u211 时如何修复 java 应用程序尺寸？

Question

所以我正在开发这个 java swing 应用程序，该应用程序当前在 Java 8 更新 192 上运行。

在此更新中它工作正常，但是当我将 java 版本升级到 8 update 211 时，它似乎更改了应用程序的 UI，因此一切看起来都更大，切换这些版本后没有进行任何代码更改。

有人知道这个问题有什么好的解决办法吗？

两个图像的相对比例相同，因此后图像更大，图标分辨率较低。

High DPI Auto-Scaling on Windows

If the Windows desktop DPI of the default screen is configured via Display Settings to be 150% or greater (that is 144 dpi or greater), JDK will now ask Windows to auto-scale the entire UI of a Java application to be consistent with the rest of the Windows desktop UI.

Below that value Java applications will appear at the same size as they did in previous releases.

This threshold is chosen as a trade-off between compatibility and legibility of the UI. At higher DPI settings, without this auto-scaling, the Java UI may be just too small to be read comfortably.

There may be some negative consequences such as

• Some elements of the UI may appear somewhat blurry, particularly if the scaling factor is a non-integral value (that is 1.5 rather than 2.0).

• ClearType text is not effective when auto-scaling so grey scale anti-aliasing is used instead by the Swing toolkit.

• Window sizing and positioning calculations may be adversely affected.

In the event that the negative consequences outweigh the benefits, an application can request the old behaviour by specifying:

-Dsun.java2d.dpiaware=true

Conversely, if the application would prefer to be auto-scaled even at lower DPI settings, then specify:

-Dsun.java2d.dpiaware=false

In the absence of either explicit setting, the default behaviour described above will apply.
