深藏阁楼爱情的钟 2023-10-18 18:18 64阅读 0赞

本文将介绍通过Java来提取或读取Word文档中文本和图片的方法。这里提取文本和图片包括同时提取文档正文当中以及页眉、页脚中的的文本和图片。

**使用工具：**Spire.Doc for Java v2.2.0

**Jar****文件导入方法：**

**方法****1**：从[官网下载][Link 1]安装包。在程序下新建一个directory目录，并命名（本示例中命名为lib）；将控件包lib文件夹下的jar（如下图1）拷贝到程序中新建的目录下。复制jar文件后，鼠标右键点击jar文件，选择”Add as Library”。完成导入（如下图2）。

**方法****2****：**通过maven导入。参考导入方法（[https://www.e-iceblue.cn/licensing/install-spirepdf-for-java-from-maven-repository.html][https_www.e-iceblue.cn_licensing_install-spirepdf-for-java-from-maven-repository.html] ）。

测试文档如下：

### **Java****代码示例（供参考）** ###

#### **【示例****1****】提取****Word****中的文本** ####

import com.spire.doc.*;
    import java.io.FileWriter;
    import java.io.IOException;
    
    public class ExtractText {
        public static void main(String[] args) throws IOException{
            //加载测试文档
            Document doc = new Document();
            doc.loadFromFile("test.docx");
    
            //获取文本保存为String
            String text = doc.getText();
    
            //将String写入Txt
            writeStringToTxt(text,"提取文本.txt");
        }
        public static void writeStringToTxt(String content, String txtFileName) throws IOException {
    
            FileWriter fWriter= new FileWriter(txtFileName,true);
            try {
                fWriter.write(content);
            }catch(IOException ex){
                ex.printStackTrace();
            }finally{
                try{
                    fWriter.flush();
                    fWriter.close();
                } catch (IOException ex) {
                    ex.printStackTrace();
                }
            }
        }
    }
