jsp用过滤器解决中文乱码问题的方法

浅沫记忆

定义一过滤器，实现Filtter接口

public class EncodingFilter implements Filter {
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
HttpServletRequest request=(HttpServletRequest)req;
HttpServletResponse response=(HttpServletResponse)resp;
request.setCharacterEncoding("UTF-8");
response.setContentType("text/html;charset=UTF-8");
chain.doFilter(req, resp);
}
@Override
public void init(FilterConfig filterConfig) throws ServletException {
// TODO Auto-generated method stub
}
}

web.xml文件中，配置过滤器

<filter>
 <filter-name>EncodingFilter</filter-name>
 <filter-class>pers.filter.EncodingFilter</filter-class>
 </filter>

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