Is there any way to generate the same UUID from a String

问题

I am wondering if there is a way to generate the same UUID based on a String. I tried with UUID, it looks like it does not provide this feature.

回答1:

You can use UUID this way to get always the same UUID for your input String:

 String aString="JUST_A_TEST_STRING";
 String result = UUID.nameUUIDFromBytes(aString.getBytes()).toString();
