Is a string, the string is generated by compiling, which eldest brother elder sister can help me get it back, we should be grateful, at the same time, the string is what kind of coding way, consult!

You look at this:

Generated GUID algorithm according to the following aspects: 1. The current date and time, 2. The network adapter card address, (3) the clockwise order, 4. Automatically incrementing counter, among them, the network card address is different, each other to machines without card, address to use the machine to keep uniqueness,
GUID code is not repeated, different environment is not possible to generate repeat GUID code, even if the same environment (the above four are the same) repetition probability is very low,

http://zh.wikipedia.org/wiki/GUID

Globally unique identifier, or GUID (pronounced/? ɡ u?? D/or/? ɡ w? D/), is A unique identifier generated by the algorithm, usually expressed as 32 hexadecimal digits (0-9, A - F) consisting of A string, such as: {ec2020-3 aea - 1069-21 b30309d A2DD - 08002}, it is essentially A 128 - bit binary integer, GUID the term is sometimes also specifically to Microsoft for UUID standards implementation,
GUID main purpose is to produce the only digital completely, in an ideal world, no computers and computer cluster is going to generate two the same GUID, GUID is big enough, the total reached $2128 (3.4 x 1038), so the possibility of randomly generated two same GUID is very small, but not to zero, so the algorithm used to generate the GUID are often joined the nonrandom parameters (e.g., time), to ensure that won't happen this duplication, (see chapter)

Generally difficult

I know, this is a Java programming UUID generated in the Oracle data, thank you
