在實(shí)際開發(fā)中我們經(jīng)常遇到request請求的中文亂碼，那么如何解決中文亂碼問題？
方法一：對請求參數(shù)進(jìn)行編碼轉(zhuǎn)換
String userName=request.getParamter("userName");
userName=new String(userName.getByte("iso-8859-1"),"utf-8");
方法二：對請求頭進(jìn)行編碼轉(zhuǎn)換
request.setCharacterEncoding("UTF-8");
備注：該方法只對POST方式提交的數(shù)據(jù)有效，對GET方式提交的數(shù)據(jù)無效!
方法三：對tomcat服務(wù)器server.xml文件設(shè)置編碼
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443" URIEncoding="UTF-8"/>
只對get請求有效但是對于post請求沒有用
SpringMVC控制器時(shí)可使用
<!-- Spring字符集過濾器 --> <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>
