在web.xml 中加入:
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<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>
修改tomcat 配置文件添加编码与工程编码一致,如下:
<ConnectorURIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
另外一种方法对参数进行重新编码:
String userName = new
String ( request . getParamter ( "userName" ). getBytes ( "ISO8859-1" ), "utf-8" )
ISO8859-1 是tomcat 默认编码,需要将tomcat 编码后的内容按utf-8 编码
