POST请求中文乱码问题解决方法:
在web.xml文件中添加编码过滤器,如下:
<!-- 解决post乱码 -->
<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>
<!-- <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value>
</init-param> -->
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
GET请求中文参数出现乱码解决方法:
方法一:
修改tomcat的配置文件server.xml添加编码URIEncoding="utf-8"与工程编码一致,如下:
<Connector URIEncoding="utf-8" connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
方法二:
对参数进行重新编码,如下:
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。
