Java 连接 mySQL demo function UTF8 避免乱码方法

 

Java连接mySQl

 

要防止乱码发生,一方面在安装mySQL时要正确制定编码的类型

 

如果发生乱码可以尝试在连接字符串中编码设置信息:

 

"jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8";

 

另外还可以尝试在建立连接之后立即设置编码类型:

 

执行SQL语句 "set names utf8"

 

    private Connection getConnection() { String driver = "com.mysql.jdbc.Driver"; try { Class.forName(driver); String url = "jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8"; String user = "root"; String password = "root"; try { Connection conn = DriverManager.getConnection(url, user, password); Statement stat=conn.createStatement(); stat.execute("set names utf8"); System.out.println("connection ok"); return conn; } catch (SQLException e) { e.printStackTrace(); return null; } } catch (ClassNotFoundException e) { e.printStackTrace(); return null; } }
