Java使用Utgard连接Wincc OPC DA 读取过程中 报错 Improper length UUID:
- 当时情况
程序跑着跑着IdentifierFactory.createUniqueIdentifier().toHexString()生成的UUID超出32位
导致GUIDUtil类中的guidStringFromHexString方法抛出异常
public static String guidStringFromHexString(String hexString) {
if (32 != hexString.length()) {
throw new IllegalArgumentException("Improper length UUID:" + hexString.length());
} else {
- 错误信息
Improper length UUID:
Exception in thread "jI_ShutdownHook" java.lang.IllegalArgumentException: Improper length UUID:37
