POST中文乱码解决方案

以前，我都是自己编写一个filter，来实现编码，代码如下：

package com.wsy.baobaotao.base.filter;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;/** * 用于设置 HTTP 请求字符编码的过滤器，通过过滤器参数encoding指明使用何种字符编码,用于处理Html Form请求参数的中文问题 */public class CharacterEncodingFilter implements Filter {protected FilterConfig filterConfig = null;protected String encoding = "";public void init(FilterConfig filterConfig) throws ServletException {this.filterConfig = filterConfig;this.encoding = filterConfig.getInitParameter("encoding");}public void doFilter(ServletRequest servletRequest,ServletResponse servletResponse, FilterChain filterChain)throws IOException, ServletException {if (encoding != null)servletRequest.setCharacterEncoding(encoding);filterChain.doFilter(servletRequest, servletResponse);}public void destroy() {filterConfig = null;encoding = null;}}

然后自己在web.xml文件中做如下配置

<filter>        <filter-name>characterEncodingFilter</filter-name>        <filter-class>com.wsy.baobaotao.base.filter.CharacterEncodingFilter</filter-class>        <init-param>            <param-name>characterEncoding</param-name>            <param-value>UTF-8</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>characterEncodingFilter</filter-name>        <span style="color:#ff0000;"><strong><url-pattern>/*</url-pattern></strong></span>    </filter-mapping>

其实我们可以不必这么麻烦，重复造轮子。

spring Web MVC框架提供了org.springframework.web.filter.CharacterEncodingFilter用于解决POST方式造成的中文乱码问题，具体配置如下：

<filter>      <filter-name>CharacterEncodingFilter</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>  </filter>  <filter-mapping>      <filter-name>CharacterEncodingFilter</filter-name>      <span style="color:#ff0000;"><strong><url-pattern>/*</url-pattern>  </strong></span></filter-mapping>

以后我们项目及所有页面的编码均为UTF-8。
