jsp傳參數到後臺出現亂碼的問題

頁面傳參出現亂碼的問題：解決思路是：jsp頁面，Tomcat以及後臺程序三者的編碼要保持一致

以UTF-8編碼格式爲例：

          1.檢查jsp頁面編碼格式是不是utf-8:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>

2.檢查Tomcat編碼格式是否爲utf-8:在Tomcat 的conf目錄下的server.xml中：  

          <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443"  URIEncoding="UTF-8"/>

         3.檢查後臺程序是否爲utf-8：以Java爲例（在web.xml中）加入下面代碼即可

<filter>
<filter-name>encodingFilter</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>encodingFilter</filter-name>
<servlet-name>dispatcher</servlet-name>
</filter-mapping>
