• 如何用java POI将word中的内容导入到mysql数据库中


    由于作业需要,要求我们将word文档中的数据直接导入到mysql中,在网上找了很常时间,终于将其解决。

    由于比较初级,所以处理的word文档是那种比较规范的那种,条例比较清晰,设计的思路也比较简单,就是根据段落的内容判断每一段是标题还是内容,然后读完一条记录后直接像数据库中添加,知道最后都添加完成。代码如下:

    本项目的结构如截图所示:

    其中Bean.java里边是一个实体类,我将每一个新闻热词的标题,内容,分类都封装在一个类中,Dao.java是实现向数据库中插入数据的函数,DBUtil.java是链接数据库,WordToSql.java里边是具体的实现代码,test.java是一个测试类。

    注:本人用的maven项目,需要导入一下依赖:

     Bean.java

    package com.chry.WordToSql;
    
    public class Bean {
        public String pian;
        public String zhang;
        public String title;
        public String content;
        public Bean(String pian, String zhang, String title, String content) {
            super();
            this.pian = pian;
            this.zhang = zhang;
            this.title = title;
            this.content = content;
        }
        public String getPian() {
            return pian;
        }
        public String getZhang() {
            return zhang;
        }
        public String getTitle() {
            return title;
        }
        public String getContent() {
            return content;
        }
        public void setPian(String pian) {
            this.pian = pian;
        }
        public void setZhang(String zhang) {
            this.zhang = zhang;
        }
        public void setTitle(String title) {
            this.title = title;
        }
        public void setContent(String content) {
            this.content = content;
        }
    
        public Bean() {
            
        }
        @Override
        public String toString() {
            return "Bean [pian=" + pian + ", zhang=" + zhang + ", title=" + title + ", content=" + content + "]";
        }
    }

    Dao.java

    package com.chry.WordToSql;
    
    import java.sql.Connection;
    import java.sql.PreparedStatement;
    import java.sql.SQLException;
    
    public class Dao {
    
        public void add(Bean bean) {
            Connection connection = DBUtil.getConnection();
            PreparedStatement preparedStatement = null;
            
             String sql = "insert into data (pian,zhang,title,content) value (?,?,?,?)";
            try {
                preparedStatement = connection.prepareStatement(sql);
                
                preparedStatement.setString(1, bean.getPian());
                preparedStatement.setString(2, bean.getZhang());
                preparedStatement.setString(3, bean.getTitle());
                preparedStatement.setString(4, bean.getContent());
                preparedStatement.executeUpdate();
                System.out.println("插入成功");
            } catch (SQLException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }finally {
                DBUtil.close(preparedStatement);
                DBUtil.close(connection);
            }
        }
        
        
    }

     DBUtil.java

    package com.chry.WordToSql;
    
    
    
    import java.sql.Connection;
    import java.sql.DriverManager;
    import java.sql.PreparedStatement;
    import java.sql.ResultSet;
    import java.sql.SQLException;
    
    
    public class DBUtil {
    public static Connection getConnection(){
     
     try {
        Class.forName("com.mysql.jdbc.Driver").newInstance();
    } catch (InstantiationException e) {
        // TODO �Զ����ɵ� catch ��
        e.printStackTrace();
    } catch (IllegalAccessException e) {

        e.printStackTrace();
    } catch (ClassNotFoundException e) {
        // TODO �Զ����ɵ� catch ��
        e.printStackTrace();
    }
     String user="root";
     String password="root";
     String url="jdbc:mysql://localhost:3306/bigdata";
     Connection connection=null;
     try {
        connection=DriverManager.getConnection(url, user, password);
    } catch (SQLException e) {

        e.printStackTrace();

    public static void close(Connection connection)
    {
     try {
         if(connection!=null)
         {
             connection.close();
         }
        
    } catch (SQLException e) {
        // TODO �Զ����ɵ� catch ��
        e.printStackTrace();
    }
     
    }
    public static void close(PreparedStatement preparedStatement)
    {
     try {
         if(preparedStatement!=null)
         {
             preparedStatement.close();
         }
        
    } catch (SQLException e) {
        // TODO �Զ����ɵ� catch ��
        e.printStackTrace();
    }
     
    }
    
    public static void close(ResultSet resultSet)
    {
     try {
         if(resultSet!=null)
         {
             resultSet.close();
         }
        
    } catch (SQLException e) {
        // TODO �Զ����ɵ� catch ��
        e.printStackTrace();
    }
     
    }
    
    }

    注:链接数据库的用户名,密码,还有数据库的名称都要根据的情况进行修改。

    import java.io.IOException;
    import java.util.List;
    
    import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
    import org.apache.poi.xwpf.usermodel.XWPFDocument;
    import org.apache.poi.xwpf.usermodel.XWPFParagraph;
    
    public class WordToSql {
    
        public static String pian;
        public static String zhang;
        
        public static void readAndWriterTest4() throws IOException { 
            File file = new File("D:\2.docx"); 
            String str = "";
            try { 
                FileInputStream fis = new FileInputStream(file); 
                XWPFDocument xdoc = new XWPFDocument(fis);
                List<XWPFParagraph> paras=xdoc.getParagraphs();
                Bean bean = new Bean();
                for(XWPFParagraph p : paras)//遍历段落
                {
                //获取段落的级别
                    String jibie = p.getStyleID();
                    
                    if(jibie!=null) {
                        if(jibie.equals("8")) {
                            pian = p.getParagraphText();
                            bean.setPian(pian);
                        }else if(jibie.equals("9")) {
                            zhang = p.getParagraphText();
                            bean.setZhang(zhang);
                            
                        }else if(jibie.equals("10")){       //判断的段落为标题
                            //System.out.println(bean.toString());
                            //写入数据库
                            Dao dao = new Dao();
                            dao.add(bean);
    bean.setContent(""); String title
    = p.getParagraphText(); bean.setTitle(title); }else { //判断段落为正文 String content = p.getParagraphText();
    if(bean.getContent()!=null) { content = content + bean.getContent(); } bean.setContent(content); } } } fis.close(); } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) throws IOException { readAndWriterTest4(); } }

    至此,便可以将一片word文档完整的导入数据库中,后续会进一步研究如何将更加复杂的word文档导入数据库中。

    注:在word文档中,每个人的字号的级别都不太一样,所以可以先写一个测试函数,输出每个段落的字号,再去修改正式导入数据库中的代码,本博客是经过修正之后的。

    如有问题,请留言。
