EndpointId在注册时有警告，无法成功注册

spring-boot 版本是2.1.6

public final class EndpointId { private static final Log logger = LogFactory.getLog(EndpointId.class); private static Set loggedWarnings = new HashSet(); private static final Pattern VALID_PATTERN = Pattern.compile("[a-zA-Z0-9.-]+"); //这里有指定不可以使用 - 而我们的名字是叫 nacos-discovery 所以注册不成功 private static final Pattern WARNING_PATTERN = Pattern.compile("[.-]+"); private final String value; private final String lowerCaseValue; private final String lowerCaseAlphaNumeric;

private EndpointId(String value) { Assert.hasText(value, "Value must not be empty"); Assert.isTrue(VALID_PATTERN.matcher(value).matches(), "Value must only contain valid chars"); Assert.isTrue(!Character.isDigit(value.charAt(0)), "Value must not start with a number"); Assert.isTrue(!Character.isUpperCase(value.charAt(0)), "Value must not start with an uppercase letter");

//此处会进入警告日志 if(WARNING_PATTERN.matcher(value).find()) { logWarning(value); }

this.value = value;
this.lowerCaseValue = value.toLowerCase(Locale.ENGLISH);
this.lowerCaseAlphaNumeric = this.getAlphaNumerics(this.lowerCaseValue);

}
