That will happen if the environment variables JAVA_TOOL_OPTIONSor _JAVA_OPTIONSare set. If you don't need them I suggest not setting them. If you are running it in Eclipse then I'd look into the "Run Configuration" or Eclipse's configuration. There is, per this SO question, no way of suppressing these messages if these variables are set, apparently.
如果设置了环境变量JAVA_TOOL_OPTIONS或_JAVA_OPTIONS设置，就会发生这种情况。如果你不需要它们，我建议不要设置它们。如果您在 Eclipse 中运行它，那么我会查看“运行配置”或 Eclipse 的配置。显然，根据this SO question，如果设置了这些变量，则无法抑制这些消息。
