post乱码、get乱码问题如何解决?
post乱码:
在web.xml文件中加入字符编码过滤器
<!-- post乱码过滤器 -->
<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>
get乱码:
方法1.
修改tomcat配置文件添加编码与工程编码一致,如下:<Connector URIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
方法2.
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
还没有评论,来说两句吧...
