这是我的Android项目中的库":
and here's the "libs" in my Android project:
如您所见,在其中 slf4j-android-1.7.25.jar .我还尝试了最新的slf4j-android-1.7.30.jar,仍然遇到了这个问题.

基本上,我正在尝试将MS WORD文件转换为pdf,这是我正在尝试在某处找到的代码:
Basically, I am trying to convert MS WORD file to pdf and here's the code I am trying which I found somewhere:
public static void docToPdf(InputStream is, String outputPath){
WordprocessingMLPackage wordMLPackage = null;
try {
wordMLPackage = WordprocessingMLPackage.load(is);
} catch (Docx4JException e) {
e.printStackTrace();
}
List sections = wordMLPackage.getDocumentModel().getSections();
for (int i = 0; i < sections.size(); i++) {
wordMLPackage.getDocumentModel().getSections().get(i)
.getPageDimensions();
}
Mapper fontMapper = new IdentityPlusMapper();
PhysicalFont font = PhysicalFonts.getPhysicalFonts().get(
"Comic Sans MS");//set your desired font
fontMapper.getFontMappings().put("Algerian", font);
try {
wordMLPackage.setFontMapper(fontMapper);
} catch (Exception e) {
e.printStackTrace();
}
/* PdfSettings pdfSettings = new PdfSettings();
org.docx4j.convert.out.pdf.PdfConversion conversion = new org.docx4j.convert.out.pdf.viaXSLFO.Conversion(
wordMLPackage);
//To turn off logger
List<Logger> loggers = Collections.<Logger> list(LogManager. getCurrentLoggers());
loggers.add(LogManager.getRootLogger());
for (Logger logger : loggers) {
logger.setLevel(Level.OFF);
}*/
OutputStream out = null;
try {
out = new FileOutputStream(new File(outputPath));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
/*conversion.output(out, pdfSettings);*/
try {
Docx4J.toPDF(wordMLPackage, out);
} catch (Docx4JException e) {
e.printStackTrace();
}
System.out.println("DONE!!");
}
进一步在控制台中,我可以看到另一条错误消息:
Further down in console, I can see another error message:
推荐答案
您需要在lib文件夹中添加slf4j-api-1.7.30.jar
. slf4j-api.jar中提供了org.slf4j.LoggerFactory类.
You need to add slf4j-api-1.7.30.jar
in lib folder. As org.slf4j.LoggerFactory class is available in slf4j-api.jar.
从 SLF4J发行版下载最新的jar文件.
Download the latest jar file from SLF4J distribution.
