.NoClassDefFoundError尝试使用pdfBox时
当我尝试使用PDFBox
示例之一提取图像时,在运行时出现以下异常:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory at org.apache.pdfbox.pdfparser.BaseParser.<clinit>(BaseParser.java:68)

这是最后两行中发生异常的代码部分:
String pdfFile = "pdf file path"; File pdf=new File(pdfFile);
PDDocument document = null;
document = PDDocument.loadNonSeq(pdf, null, password);
document = PDDocument.load( pdfFile );
回答:
在您的lib目录中添加commons-logging-1.1.1.jar或jcl-over-slf4j-1.7.6.jar。
