最近开始又转向J2EE的开发。很久没用,重新熟悉。
本地环境ubuntu 12.13,mysql5.x,tomcat7.x,struts2.3.15.x,spring3.1.0,hibernate4.1.x
之前一直连线上服务器上测试数据库,没有发现有中文乱码问题。
现在在本地搭建此环境,使用本地数据库,便于调试,但是发现每次对数据库操作,有中文就会出现????乱码。
那现在一步步排除什么原因引起:

CREATE TABLE `gamepad_model` ( `edit_id` varchar(50) NOT NULL, `filedata` text, `gamepad_type` varchar(100) NOT NULL, `pic_url` varchar(255) DEFAULT NULL, `sdk_version` varchar(50) NOT NULL, `update_date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP, PRIMARY KEY (`edit_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8需要加上: CHARSET=utf8
insert into gamepad_model(edit_id,filedata,gamepad_type,sdk_version) values('test3_测试','ttt','testtt_你好','1');如果没有问题,则排除mysql问题
mydata.url=jdbc:mysql://localhost:3306/sdk?useUnicode=true&characterEncoding=UTF-8一般不在xml中,连接数据库需要加上
useUnicode=true&characterEncoding=UTF-8但是如果在xml中,需要转意一下
