Commodity barcode (Jbarcode) Java Edition (ii)

Afternoon open an afternoon meeting, in fact, meeting I listen to not go in, because today demon are particularly cold, work in the company waiting for Xiaoxifu one head, then take her to eat, eat dinner back home. When she was exercising, I began to slowly organize my own little blog.

--Preface

　　　

First of all, the purpose of writing this article is to improve the previous article everyone's question, although it is a simple function, but the last time is simply to make a function, and this time is to continue on the basis of the last function, do some optimization work, to their own life to add some records, put forward for everyone to learn, is also a way of learning. Every time after learning new things, it is necessary to comb, but also slowly become a part of life, feel this is a kind of self-habit.

I'm not going to say a lot of jar bags here.

Jbarcode, download the latest version: Jbarcode-0.2.8.jar, I basically go to the official website to download some things, some you do not know the answer, in the network basically have, so it is recommended that we all go to the official website to browse.

　　

Here's the beginning of the results code, you can download the Utils tool class yourself and apply it to your project. (Note: according to their own needs to set the corresponding parameters can be)

Through this time of optimization, let me know the importance of the source code, want to know something in-depth, you need to understand the internal, with learning knowledge to arm themselves, rookie study, Big Bird do not spray, just record, by the way to those who do not love their brains, if you like me this way, please click on the lower right corner of the recommendation,

Sleep, Xiaoxifu exercise also finished ...
