1.maven项目进入依赖
?<dependency> ???<groupId>org.xhtmlrenderer</groupId> ???<artifactId>core-renderer</artifactId> ???<version>R8pre2</version></dependency><dependency> ???<groupId>com.lowagie</groupId> ???<artifactId>itext</artifactId> ???<version>2.0.8</version></dependency><dependency> ???<groupId>com.itextpdf</groupId> ???<artifactId>itextpdf</artifactId> ???<version>5.4.4</version></dependency>
2.将html页面进行封装
