SpringMVC Controller 接收页面传递的中文参数出现乱码(转)
在Controller中接收到的POST参数如果是中文的话,显示为乱码。已知客户端传过来时编码为UTF-8。
问题产生分析:
spring MVC中默认的编码格式为“ISO-8859-1”,因此造成乱码。
简单的解决方式:
New String(request.getParameter("xxx").getBytes("iso-8859-1"),"utf-8")
最好的解决方式:
在web.xml中配置Spring字符过滤器,添加:
<!-- Spring字符集过滤器 -->
<filter> <filter-name>SpringEncodingFilter</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>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
GET方法接收到中文乱码在tomcat的server.xml添加URIEncoding="utf-8"
<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> 变更为: <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="utf-8"/>
