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) {
    // TODO �Զ����ɵ� catch ��
    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) {
    // TODO �Զ����ɵ� catch ��
    e.printStackTrace();
}
return connection;
 
}

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。

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。如有问题，请留言。
