    public class EncodeFilter implements Filter {
        public void destroy() {
        }

        public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws ServletException, IOException {
            req.setCharacterEncoding("utf-8");
            resp.setCharacterEncoding("utf-8");
            resp.setContentType("utf-8");
            chain.doFilter(req, resp);
        }

        public void init(FilterConfig config) throws ServletException {

        }

    }

    web.xml配置

    <filter>
        <filter-name>EncodeFilter</filter-name>
        <filter-class>com.lwj.filter.EncodeFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>EncodeFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

  2. 使用Spring提供的过滤器

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