中文化问题的解决方案 CharactorEncodingFilter

    多的就不说了，只是一个基本的CharactorEncodingFilter的代码：

java 代码

public class CharactorEncodingFilter implements Filter {

    private String charactorEncoding;

    private static final String CHARACTOR_ENCODING_PARAMETER_NAME = "charactorEncoding";

    @Override
    public void destroy() {
        //什么也不用做。
    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        request.setCharacterEncoding(this.charactorEncoding);
        response.setCharacterEncoding(this.charactorEncoding);
        chain.doFilter(request, response);
    }

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        this.charactorEncoding = filterConfig.getInitParameter(CHARACTOR_ENCODING_PARAMETER_NAME);
    }

}

    然后在web.xml中使用这个Filter

xml 代码

<filter>
  <description>处理中文化问题</description>
  <filter-name>charactorEncodingFilter</filter-name>
  <filter-class>
    cn.com.gxlu.fiberscheduler.web.util.CharactorEncodingFilter
  </filter-class>
  <init-param>
    <param-name>charactorEncoding</param-name>
    <param-value>UTF-8</param-value>
  </init-param>
</filter>

<filter-mapping>
  <filter-name>charactorEncodingFilter</filter-name>
  <url-pattern>*.do</url-pattern>
</filter-mapping>
