1、web的配置：
（1）、设置错误跳转界面：
这里写图片描述
（2）、字符串编码配置：

 <!-- 字符集编码配置 -->  <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>

（3）、配置serlvet 拦截请求脱离struct2之外

  <filter>        <filter-name>redisp</filter-name>        <filter-class>yamadv.com.filter.ReDispatcherFilter</filter-class>        <init-param>            <param-name>includeServlets</param-name>            <param-value>FileImageUploadServlet,uploadProcessorServlet</param-value>        </init-param>    </filter>    <filter-mapping>        <filter-name>redisp</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>

/// 该配置集合的类（实现filter）：
实现多个servet在web.xml中的配置

public class ReDispatcherFilter implements Filter {    public void destroy() {}    public void doFilter(ServletRequest req, ServletResponse resp,            FilterChain chain) throws IOException, ServletException {        HttpServletRequest request = (HttpServletRequest) req;        String target = request.getRequestURI();        target = target.lastIndexOf("?") > 0 ? target.substring(                target.lastIndexOf("/") + 1,                target.lastIndexOf("?") - target.lastIndexOf("/")) : target                .substring(target.lastIndexOf("/") + 1);        System.out.println(target);        if (this.includes.contains(target)) {            RequestDispatcher rdsp = request.getRequestDispatcher(target);            System.out.println("go..............." + rdsp);            rdsp.forward(req, resp);        } else{            chain.doFilter(req, resp);        }    }    private ArrayList<String> includes = new ArrayList<String>();    public void init(FilterConfig config) throws ServletException {        this.includes.addAll(Arrays.asList(config.getInitParameter(                "includeServlets").split(",")));    }}

//////要注册的servet（上传文件到服务器）：

<!-- 注册 FileImageUploadServlet 的servlet -->   <servlet>        <servlet-name>FileImageUploadServlet</servlet-name>        <servlet-class>yamadv.com.upload.FileImageUploadServlet</servlet-class>    </servlet>    <servlet-mapping>        <servlet-name>FileImageUploadServlet</servlet-name>        <url-pattern>/FileImageUploadServlet</url-pattern>    </servlet-mapping>
