1. Mysql在java中的使用步骤

-1.配置数据库：http://www.cnblogs.com/sshoub/p/4321640.html

2.创建可以远程的登录用户：http://www.cnblogs.com/xyzdw/archive/2011/08/11/2135227.html

grant all privileges on *.* to testuser@"%" identified by "password" ;

3.数据库操作：

•  创建数据库以及表

DROP TABLE
IF EXISTS mq_message_content;

CREATE TABLE mq_message_content (
    task_id VARCHAR (255) NOT NULL CHECK (task_id != ''),
    type VARCHAR (255) NOT NULL,
    msgcontent LONGTEXT NOT NULL,
    time VARCHAR (50) NOT NULL,
    PRIMARY KEY (task_id, type)
) DEFAULT CHARSET = 'utf8';

 4. Java代码连接数据库，进行相应的操作

Class.forName(dbDriver).newInstance();
Connection conn = DriverManager.getConnection(dbUrl, dbUsername, dbPassword);
PreparedStatement pst = conn.prepareStatement(sql);
