如何使用docx4j合并两个docx文件？

Question

我有两个docx文件要合并，我在docx4j中有以下代码，但有一些错误！ docx文件都用于跟踪更改。因此输出文件应该包含两个docx文件的详细信息。

     String[] files = {"table.docx", "Table1.docx"}; 
     List blockRanges = new ArrayList(); 
     for (int i=0 ; i< files.length; i++) { 
     BlockRange block = new BlockRange(WordprocessingMLPackage.load(new File(DIR_IN + files[i]))); 
        blockRanges.add( block ); 
        block.setStyleHandler(StyleHandler.RENAME_RETAIN);
        block.setNumberingHandler(NumberingHandler.ADD_NEW_LIST);
        block.setRestartPageNumbering(false);

        block.setSectionBreakBefore(SectionBreakBefore.NEXT_PAGE);
    } 
        // Perform the actual merge 
        DocumentBuilder documentBuilder = new DocumentBuilder(); 
        WordprocessingMLPackage output = documentBuilder.buildOpenDocument(blockRanges); 
       // Save the result 
       SaveToZipFile saver = new SaveToZipFile(output); 
       saver.save(DIR_OUT+"OUT_MergeWholeDocumentsUsingBlockRange.docx"); 
       } 
    }
