java面试题:SrpingMvc如何解决POST请求中文乱码问题,GET的又如何处理呢?
解决post请求乱码问题:
在web.xml中加入:
<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>
解决post请求乱码问题:
get请求中文参数出现乱码解决方法有两个:
1.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"/>
2.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
