如何在MySQL中存储图片?

我想将图像存储在MySQL数据库中。 我创建了一个具有BLOB数据类型的表,但现在如何将图像存储在此表中?

您可能需要查看以下示例:

来自java2s.com:将图片插入MySQL

import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; public class InsertPictureToMySql { public static void main(String[] args) throws Exception, IOException, SQLException { Class.forName("org.gjt.mm.mysql.Driver"); Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/databaseName", "root", "root"); String INSERT_PICTURE = "INSERT INTO MyPictures (photo) VALUES (?)"; FileInputStream fis = null; PreparedStatement ps = null; try { conn.setAutoCommit(false); File file = new File("/tmp/photo.png"); fis = new FileInputStream(file); ps = conn.prepareStatement(INSERT_PICTURE); ps.setBinaryStream(1, fis, (int) file.length()); ps.executeUpdate(); conn.commit(); } finally { ps.close(); fis.close(); } } } 

MySQL表:

 CREATE TABLE MyPictures ( photo BLOB ); 

如果映像位于MySQL服务器主机上,则可以使用MySQL客户端的LOAD_FILE()命令:

 INSERT INTO MyPictures (photo) VALUES(LOAD_FILE('/tmp/photo.png')); 

读取文件的内容(BINARY)并将其插入insert \ update MYSQL查询中

谷歌中有很多例子:
