bch编码，可以自己输入纠正个数，自定义码长，内有两个不一样的算法，都能正确执行。-bch encoding can enter the number of corrections, custom code length, with two different algorithms can be executed correctly.

使用zxing完成的简单地二维码生成器，基于java1.7，可以实现二维码图像的生成和解析，使用bch码来进行纠错。-Zxing easily accomplished using a two-dimensional code generator based java1.7, two-dimensional code image can generate and parse using bch codes for error correction.
