Here is the code: private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { try{ FileOutputStream outStream=new FileOutputStream("New.docx"); XWPFDocument doc =new

纯解释执行（启动很快，执行很慢） -Xint 纯编译执行（启动很慢，执行很快） -Xcomp 混合执行（默认） -Xmixed 设置热点代码（JVM使用编译执行的条件） -XX:CompileThreshold=10000 测试 public class MyTest { public static void main(String[] args) { long t1 = System.currentTimeMillis(); for (int i = 0; i < 100000; i++) { myLoop(); } long t2 = System.currentTimeMillis(); System.out.println(t2 - t1); } public static void myLoop(){ for (int i = 0; i < 1000000; i++) { int j = i / 2; } } } 三种模式分别测试的结果： 纯解释： 实在太久，直接放弃...... 纯编译： 有一定的编译时间， 执行时间为 2 混合： 编译很快， 执行时间为 5 来源： oschina 链接： https://my.oschina.net/icefoxhz/blog/4956878

Remove XMP Metadata on PDF/A

由 本秂侑毒 提交于 2021-02-19 22:38:38
问题 Is there a way wherein we can remove XMP metadata on a PDF/A Document without removing the PDF/A standardization? I found that using PdfReader reader = new PdfReader(src); PdfDictionary dict = reader.getCatalog(); dict.remove(PdfName.METADATA); dict.remove(PdfName.PROPERTIES); reader.removeUnusedObjects(); Removes both XMP and PDF/A. Is there a way to remove the XMP while retaining the standard or reintroducing PDF/A into the processed document? Thanks. 回答1: You can't remove the XMP
