我嘗試以一個DOCX文件轉換爲PDF格式，使用此代碼使用documents4j（https://bintray.com/raphw/maven/documents4j）： 非常感謝你提前，我沒有做它工作的想法Documents4j IllegalStateException異常
package documents4j;
import java.io.File;
import java.util.concurrent.Future;
import java.util.concurrent.TimeUnit;
import com.documents4j.api.DocumentType;
import com.documents4j.api.IConverter;
import com.documents4j.job.LocalConverter;
public class HelloPDF {
public static void main(String[] args) {
File wordFile = new File("c:/datos/Resultados.docx"), target = new File("c:/datos/Resultados.pdf");
IConverter converter = LocalConverter.builder().baseFolder(new File("c:/datos/"))
.workerPool(20, 25, 2, TimeUnit.SECONDS)
.processTimeout(5, TimeUnit.SECONDS).build();
Future<Boolean> conversion = converter.convert(wordFile).as(DocumentType.DOCX).to(target).as(DocumentType.PDF)
// .prioritizeWith(1000) // optional
.schedule();
}
}
但即時遇到非法狀態
