Java 具有swing系统托盘图标的高CPU使用率
在我使用的一个简单的swing应用程序中 代码正常，创建托盘，设置图标，添加事件。但当应用程序使用系统托盘执行时，CPU使用率高达50%。如果未使用系统托盘代码，则CPU使用情况良好。如何解决这个问题 编辑： 下面是代码，虽然不是完整的源代码，但主要的两个java文件如下：Java 具有swing系统托盘图标的高CPU使用率,java,swing,system-tray,Java,Swing,System Tray,在我使用的一个简单的swing应用程序中 代码正常，创建托盘，设置图标，添加事件。但当应用程序使用系统托盘执行时，CPU使用率高达50%。如果未使用系统托盘代码，则CPU使用情况良好。如何解决这个问题 编辑： 下面是代码，虽然不是完整的源代码，但主要的两个java文件如下： package ui; import java.awt.BorderLayout; import java.awt.Component; import java.awt.MenuItem; import java.awt.
