1.表单提交一定要指定method,否则下面如何改都没用
2.jsp页面中指定pageEncoding=utf-8,jsp用utf-8来保存
request.setCharacterEncoding("utf-8")
2.使用spring的filter,在web.xml中加入
<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-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
4.struts.xml中加入常量
<constant name="struts.i18n.encoding" value="UTF-8" />
5.数据库的编码方式改成utf-8
SET NAMES ‘x‘语句与这三个语句等价：
mysql> SET character_set_client = x;
mysql> SET character_set_results = x;
mysql> SET character_set_connection = x;
