导入依赖

导入POI主要的依赖：

<!-- 用于对文件操作，例如写操作 -->
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>3.15</version>
</dependency>
<!-- .docx解析依赖 -->
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>3.15</version>
</dependency>
<!-- .doc解析依赖 -->
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-scratchpad</artifactId>
    <version>3.15</version>
</dependency>
<!-- .pdf解析依赖 -->
<dependency>
    <groupId>org.apache.pdfbox</groupId>
    <artifactId>pdfbox</artifactId>
    <version>2.0.4</version>
</dependency>
<!-- 单元测试依赖，也可以自己写一个测试类，这个无关紧要 -->
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

需要保持上面的依赖的版本的一致性。不然会报各种莫名其妙的错！

        } else if (filePath.toLowerCase().endsWith("docx")) {
            OPCPackage opcPackage = POIXMLDocument.openPackage(filePath);
            POIXMLTextExtractor extractor = new XWPFWordExtractor(opcPackage);
            text = extractor.getText();
            opcPackage.close();
            extractor.close();
        } else if (filePath.toLowerCase().endsWith("pdf")) {
            PDDocument pdDocument;
            InputStream file = new FileInputStream(new File(filePath));
            pdDocument = PDDocument.load(file);
            PDFTextStripper stripper = new PDFTextStripper();
            text = stripper.getText(pdDocument);
            file.close();
            pdDocument.close();
        } else {
            return "error file";
        return text;
}

测试

public static void main(String[] args) throws XmlException, OpenXML4JException, IOException {
//        String filePath = "F:\\extract\\20181226163749u1xcw.pdf";
        String filePath = "F:\\extract\\12.docx";
        try {
            String s = FileExtract.fileExtractText(filePath);
            System.out.println(s);
        } catch (Exception e) {
            e.printStackTrace();
    }

结果分析：
通过工具扫描出来的PDF不能提取出文字。
