mysql的中文乱码问题

1.安装服务器时指定字符集为UTF-8。
2.建数据库时指定字符集为UTF-8,我的数据库（ＭＹＳＱＬ）的字符集是通过ENGINE=InnoDB DEFAULT CHARSET=utf8;设置成“ＵＴＦ８”的
3.在web.xml里设计过滤器字符集为utf-8
<filter></filter>
<filter-name></filter-name><filter>
  <filter-name>encodingFilter</filter-name>
  <filter-class>
   org.springframework.web.filter.CharacterEncodingFilter
  </filter-class>
  <init-param>
   <param-name>encoding</param-name>
   <param-value>UTF-8</param-value>
  </init-param>
 </filter>

<filter-mapping></filter-mapping><filter-mapping>
  <filter-name>encodingFilter</filter-name>
  <url-pattern>*.do</url-pattern>
 </filter-mapping>
 <filter-mapping>
  <filter-name>encodingFilter</filter-name>
  <url-pattern>*.jsp</url-pattern>
 </filter-mapping>
4.配置spring配置文件，指定连接字符串.
applicationContext.xml里也是
jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
以上基本上可以解决中文乱码问题了..
