spring 框架java后台获取的中文解决办法

首先，jsp页面的编码必须是一致的，我这里是有的UTF-8，如：

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

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8" />

接着，可以使用spring 的CharacterEncodingFilter

在web.xml文件配置filter过滤器

<filter>
<description>字符集过滤器</description>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<!-- 配置参数 -->
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>encoding</param-name>
<param-value>ISO-8895-1</param-value>
</init-param>
</filter>

<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
