乱码问题

Question

页面post提交，中文出现乱码该如何解决？

Answer 1

写个过滤器吧，把请求响应统一编码
过滤器核心代码为：
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain filter) throws IOException, ServletException {
// 字符过滤
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
// 清空缓存
HttpServletResponse resp = (HttpServletResponse) response;
resp.setDateHeader("Expires", -1);
resp.setHeader("Cache-Control", "no-cache");
resp.setHeader("Pragma", "no-cache");
}

Answer 2

在web.xml中配置
<!-- 字符集过滤器配置 -->
<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>
<url-pattern>/*</url-pattern>
</filter-mapping>
在jsp中配置
<%@ page language="java" pageEncoding="UTF-8"%>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8"/>试一试这个方法行不行

首先设置你的jsp页面的编码，如果还不行就添加过滤器吧！！
