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 的通知区域图标中，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。
启动4j
Launch4j 是一个跨平台工具，用于将作为 jar 包分发的 Java 应用程序打包到轻量级 Windows 本机可执行文件中。
以下是我创建它的步骤：
- 基本的
- 设置输出文件名
- 选择“不包装罐子，仅启动”
- 输入 .jar 文件的相对路径
（我建议使用相同的文件夹以及 .exe 和 .jar 文件）
- 类路径
这是必要的，因为我们不会通过 javaw.exe 或 java.exe 启动，
只需导航到“主类”下的 .jar 文件就足够了，
您应该看到主类出现并且列表应该为空 - Header
Header Type: JNI GUI (beta)，来自文档：当使用 JNI 标头时，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。进程名称将与包装器相同。
- JRE
- 输入适当的最低 JRE 版本
- 选择 32-bit only , JNI headers 当前与 64-Bit JRE 不兼容
- 版本信息
- 检查添加版本信息
- 填写所有必填字段文件描述
条目 显示在 Windows 通知中
现在剩下要做的就是保存配置并构建。你会看到这样的警告：
警告：JNI 标头中未实现某些功能，请参阅文档。
这些限制可以在 <headerType> 下找到。
您当然可以使用完全不同的选项，例如捆绑 JRE 或将 .jar 捆绑到 .exe 文件中。
