最近公司项目有个需求，批量打印荣誉证书，一开始尝试过传统的Web打印，控件打印，js调用浏览器打印方法，遇到各种问题，比如定位不准，分页问题，缩放问题等。然后就自己研究，整理了一套打印方案，项目已测试通过，现在把这一成果分享给大家。
下面，我会提供一个工具类，这个工具类里，会有两种打印方案：
一. 把要打印的内容，放到html代码中，然后解析html（虽然支持解析样式，由于支持的样式非常少，字体字号样式都不支持，所以这种方式并没有太大意义），解析后生成pdf文件，然后下载到客户端。
二.先生成多页的空白PDF，然后将文字通过添加水印（可设置透明度）的方式，输出指定位置。
注意事项：在这个过程中，会产生一些临时文件，注意临时文件存放目录，由于项目运行时必然有并发问题，临时文件名一定要取时间戳或UUID这种不会重复的名字，还有临时文件使用完成后要及时删除，删除前要关闭 IO流对象，pdf书写器对象（关闭要由外到里，一定要close掉，因为 JVM 的GC 无法回收这些资源，否则是不能删除这些被占用的临时文件的）
