将字节数组写入PDF文件 示例代码 下面是一个简单的示例代码,演示了如何将Base64字符串转换为PDF文件: importjava.io.FileOutputStream;importjava.util.Base64;publicclassBase64ToPDF{publicstaticvoidmain(String[]args){Stringbase64String="JVBERi0xLjMKJcTl8uXrp/Og0MTGCjIuMjAxMi0wNC0yOSAw...";// 这里...
/** * 超长base64字符串转pdf文件 * @param filePath * @throws IOException */publicstaticvoidbase64StringToPdf(StringfilePath)throwsIOException{Filefile1=newFile("D://base64.txt");InputStreamin=newFileInputStream(file1);BASE64Decoderdecoder=newBASE64Decoder();byte[]bytes=newbyte[0];try{bytes...
然后,你可以使用以下Java代码来实现Base64到PDF的转换: java import java.io.FileOutputStream; import java.io.IOException; import java.util.Base64; // 假设Apache PDFBox的PDDocument等类已正确导入 public class Base64ToPDF { public static void main(String[] args) { // 示例Base64编码的PDF数据(这里...
