Incorrect string value: '\xE5\x86\x99\xE7\x9A\x84...'

测试环境：MySql5.1+Hibernate3.5+MyEclipase8

 

原因：我在项目中向mysql插入中文字符为乱码，于是我将mysql安装目录下的my.ini文件中的default-character-set修改为gb2312。然后再次执行java代码，抛出如下异常：

 

737 [main] WARN org.hibernate.util.JDBCExceptionReporter - SQL Error: 1366, SQLState: HY000

解决办法：

使用mysql的配置工具重新配置一个新的实例（设置编码为gb2312），

 

然后在将原来数据库的表重建（因为在创建表时DEFAULT CHARSET=latin1）
