### **maven配置** ###

*  【版本差异会出现STSong-Light' with 'UniGB-UCS2-H' is not recognized错误】
 *  【下面的依赖配置解决了上述的问题】

<dependency> <groupId>com.itextpdf</groupId> <artifactId>itext-asian</artifactId> <version>5.2.0</version> </dependency>  <dependency> <groupId>com.itextpdf</groupId> <artifactId>itextpdf</artifactId> <version>5.4.3</version> </dependency>

### **工具类** ###
