MySql乱码的问题

MySql乱码的问题

今天,做一个Demo.程序用utf-8,mySql数据库用utf-8,但是插进去的数据还是乱码.
解决方法如下:

< bean  id ="dataSource"
        class ="com.mchange.v2.c3p0.ComboPooledDataSource"
        destroy-method ="close" >
         < property  name ="driverClass"  value ="com.mysql.jdbc.Driver"   />
         < property  name ="jdbcUrl"
            value ="jdbc:mysql://127.0.0.1:3306/mydata?useUnicode=true&amp;characterEncoding=utf-8" />
         < property  name ="user"  value ="root"   />
         < property  name ="password"  value ="root"   />
         < property  name ="autoCommitOnClose"  value ="true"   />
         < property  name ="checkoutTimeout"  value ="5000"   />
         < property  name ="initialPoolSize"  value ="2"   />
         < property  name ="minPoolSize"  value ="2"   />
         < property  name ="maxPoolSize"  value ="4"   />
         < property  name ="maxIdleTime"  value ="25200"   />
         < property  name ="acquireIncrement"  value ="1800"   />
         < property  name ="maxIdleTimeExcessConnections"  value ="5"   />
     </ bean >
