jsp表单提交中文乱码方式----提交方式为:post

（1）Tomcat 的 conf 下的server.xml文件中将bai
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
里添加上后面3个编码的设置
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
useBodyEncodingForURI="true"
IEncoding="utf-8"
URIEncoding="utf-8"/>
（2）
然后在servlet中配置如下：
如果你用的是 post方式
解决方案：
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding( "utf-8" );

(3).在web.xml中设置编码过滤器

<filter>
<filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
