怎么高大效解决Java导出PDF换行无效问题？

哎呀， 细小猫咪们，今天我们要来聊聊一个让hen许多Java程序员头疼的问题：Java导出PDF时中文内容换行无效的问题。别急，跟着我一起探索解决办法吧！

周围准备

先说说我们要准备一下周围，就像我们准备画画的画板一样。这里我们用到的代码如下：

import java.io.OutputStream;
File file = new File;
Document document = new Document;
//自己Zuo的一个轻巧松例子， 中间有图片之类的
}

这里我们创建了一个PDF文件，巨大细小是A4纸，四周留白。就像我们画画时留白一样，让画面kan起来geng舒服。

Java解决Itext生成PDF中文不换行的问题

哦哦， 说到Itext，这是一个hen厉害的工具，Neng帮我们生成PDF文件。但是有时候它会闹点细小脾气，比如中文内容不换行。不过别担心，我有办法解决它！ 代码如下：

//当然你也Neng用你电脑里面带的字体库
Document document = new Document;
import java.io.*;
/** 
 * @author lcq 
 * @create 2020/5/22 */ 
@Slf4j 
public class ExcelToPdfUtil { 
    /** 
     * 获取license 去除水印 
     * @return */ 
    public static boolean getLicense{ 
        boolean result =false; 
        try { 
            InputStream is = ExcelToPdfUtil.class.getClassLoader.getResourceAsStream; 
            License aposeLic = new License; 
            aposeLic.setLicense; 
            result =true;
        } catch { 
            e.printStackTrace;
        }return result;
    } 
    public static void excel2pdf{ 
        // 验证License 若不验证则转化出的pdf文档会有水印产生 
        if){return;} 
        try { 
            // 原始excel路径...
        } catch  { 
            document.open;
            import com.itextpdf.text.Document;
            //保存本地指定路径
            file.close;
            img2.setAbsolutePosition;
            BaseFont bfChinese = BaseFont.createFont;
            //获取此编译的文件路径
            import java.io.File;
            PdfWriter.getInstance;

            response.setHeader;

            repository
            iText类库了。

            file.close;
            img2.setAbsolutePosition;
            BaseFont bfChinese = BaseFont.createFont;
            /repository/repositoriesdependencies
            document.add);
            //直接生成PDF 制定生成到D盘test.pdf
            document.add;
            拓展：
            Workbook workbook = new Workbook;
            // PdfWriter writer = PdfWriter.getInstance;
            //设置文档保存的文件名
            //这里根据自己的获取的路径写 只要找到图片位置就Neng
            函.pdf").getBytes, "ISO--") + "\\\\");
            //获取图片
