我创建了一个支持系统托盘通知的程序。我为我的系统托盘设置了一个带有工具提示和气球消息的图标。当我启动程序时，图标出现在Windows中的通知区图标中，旁边的默认名称是Java（TM）Platform SE Binary。我可以将此默认名称更改为自定义名称，例如我的程序名称吗？

我今天遇到了同样的问题。正如Petesh在评论中提到的，我使用自定义启动器来解决这个问题。
Launch4j是一个跨平台工具，用于将Java应用程序包装为轻量级Windows本机可执行文件中的jar。
以下是我创建它的步骤：
当使用JNI头时，jVM由launch4j包装器可执行文件直接创建，而不是运行java / javaw启动器。进程名称与包装器相同。
现在剩下要做的就是保存配置和构建。 你会看到这样的警告：
警告：某些功能未在JNI标头中实现，请参阅文档。
可以在＆lt; headerType＆gt;。
下找到here这些限制您当然可以使用完全不同的选项，例如捆绑的JRE或在.exe文件中捆绑.jar。
