在询问之前我经常搜索过很多 . 我已经创建了一个Jhipster微服务应用程序（v 3.12），我使用iText库基于模板生成我自己的PDF .
我在另一个项目中测试了 GeneratePdfFromPdfTemplate class （不是Spring Boot，而是一个简单的maven项目）并且它工作得很好;但是当我在我的JHipster项目中运行它时，新的 FileOutputStream 指令会导致问题：
public static void generatePdf（String src，String dest，String codiceAvviso）{
try {
PdfReader reader = new PdfReader(src);
FileOutputStream fos = new FileOutputStream(dest);
PdfStamper stamper = new PdfStamper(reader, fos);
PdfContentByte canvas = stamper.getOverContent(1);
...
当我调试它时，新的FileOutputStream（dest）;强制重启我的应用程序导致此日志：

src和dest字符串分别是：src：
C：\ Users \ Administrator \ Documents \ NetBeansProjects \ Xenia \ src \ main \ resources \ templateAgid.pdf
