Java 尝试运行示例spring引导应用程序时，url EXCEPTION格式错误

我第一次尝试在SpringToolSuite4上运行示例SpringBoot应用程序 版本：4.8.1.0版本和JDK

java version "1.8.0_251"
Java(TM) SE Runtime Environment (build 1.8.0_251-b08)
Java HotSpot(TM) Client VM (build 25.251-b08, mixed mode)

当尝试将示例应用程序作为Spring Boot运行时，会出现以下异常

Picked up JAVA_TOOL_OPTIONS: -Djdk.lang.Process.allowAmbiguousCommands=true
Error: Exception thrown by the agent : java.net.MalformedURLException: Service URL contains non-ASCII character 0x666

可能是您计算机的主机名包含一个非ascii字符，spring正在JMX URL中使用该字符。 如果不需要JMX监视，请使用以下属性禁用它

spring.jmx.enabled=false

您的应用程序代码有问题，但尚未发布应用程序代码。错误消息非常清楚

java.net.MalformedUrl异常：服务URL在java.management/javax.management.remote.JMXServiceURL.（JMXServiceURL.java:157）处包含非ASCII字符0x666。

投票关闭引发的异常位于java.management/javax.management.remote.JMXServiceURL，这是我没有编写的类！但是您在应用程序的某个地方使用了JMX，并且在应用程序的某个地方定义了一个明显格式错误的URL。您知道代码不会自动使用自身吗？发布足够的代码，以便我们可以复制并运行您的应用程序，并获得相同的异常。因为您没有发布任何东西，所以将使用所有类更新帖子。我已将此属性添加到应用程序的属性文件中，并尝试了相同的错误发生，并且application.properties显示warinign endpoints.jmx.enabled是未知属性我刚刚更改了，它是“spring.jmx.enabled”，也发生了相同的错误，我的主机名是：OSMOHAME-EGI检查了异常中引用的字符；是٦（阿拉伯语-印度语中的数字6），您的窗口是否可以设置为以非英语格式显示数字
