html转pdf：

import com.itextpdf.html2pdf.ConverterProperties;

import com.itextpdf.layout.font.FontProvider;

import java.io.File;
import java.io.IOException;

/**

public class PdfTest {


    private static void html2Pdf(){
        ConverterProperties converterProperties =  new ConverterProperties();
        //指定目录，支持将html相对路径的图片转换到pdf，注意pom文件需要配置将img文件加入到编译后的项目中
        converterProperties.setBaseUri("C:\\Users\\Desktop\\PDF\\");
        FontProvider fontProvider = new FontProvider();
        fontProvider.addDirectory("C:\\Users\\Desktop\\PDF\\ttf");

        //读取的html文件地址

        //生成的pdf地址
        File pdfFile = new File("C:\\Users\\Desktop\\PDF\\lgn.pdf");

        } catch (IOException e) {

        }
    }

    public static void main(String[] args) {
        html2Pdf();
    }
}

pom文件：

<!--将html转换成pdf-->
    <dependency>
      <groupId>com.itextpdf</groupId>
      <artifactId>html2pdf</artifactId>
      <version>2.0.2</version>
    </dependency>

设置中文字体，ttf文件夹下SimSum-01和Dengb分别支持细字体和粗字体，缺一不可
