jsp 提交表单乱码解决方案（post/get）
解决乱码基本上添加拦截器就可以了，get / post 提交都全部搞定。不过第二条经过我的验证，不设置视乎也可以。
第一条是在action里面对接收到的单条参数进行转换
1. String name=new String((user.getUname()).getBytes("ISO-8859-1"),"utf8");
2. 在TOMCAT 6 的 server.xml里面设置：(tomcat 7 不支持)
添加：URLEncoding="UTF-8"
<Connector port="6060" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" URIEncoding="UTF-8"
useBodyEncodingForURI="true"
/>
3. 自己写Filter ：必须放在web.xml的最前面。下面2个拦截器都可以用，经过测试了
<!-- struts 的中文乱码拦截器
<filter>
<filter-name>encodeFilter</filter-name>
<filter-class>com.soodeep.util.MyEncodingIntercpter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GBK</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodeFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
-->
<!-- spring的中文乱码拦截器
<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>
-->
