post中文乱码
对于post请求时出现乱码解决方法:
- 在web.xml中加入:
<!-- post乱码过虑器 -->
<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中文乱码
对于get请求中文参数出现乱码解决方法有两个:
- 修改tomcat配置文件,添加编码与工程编码一致:(ISO8859-1是tomcat默认编码)
<Connector URIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
- 代码中对参数进行重新编码:(将tomcat编码后的内容按utf-8编码)
String userName = new String(request.getParamter("userName").getBytes("ISO8859-1"),"utf-8");
