使用servlet别名的旧式servlet链接

我不太熟悉servlet链接的实现细节，但是这是一种可行的通用方法。将两个servlet映射到不同的URL：

<servlet-mapping>    <servlet-name>process</servlet-name>    <url-pattern>/process</url-pattern></servlet-mapping><servlet-mapping>    <servlet-name>translate</servlet-name>    <url-pattern>/translate</url-pattern></servlet-mapping>

然后将过滤器映射到

process

<filter-mapping>    <filter-name>processChain</filter-name>    <servlet-name>process</servlet-name></filter-mapping>

该

processChain

public void doFilter(ServletRequest request,          ServletResponse response,          FilterChain chain) throws IOException, ServletException {    ServletResponseWrapper processResponse = ...; // response buffer    chain.doFilter(request, processResponse); // let process servlet populate response buffer    ServletRequestWrapper processResponseAsRequest = ...; // use processResponse to create request for translate servlet    RequestDispatcher dispatch = request.getRequestDispatcher("/translate");    dispatch.forward(processResponseAsRequest, response); // forward to translate servlet with response from process servlet as the request and the original response}

…或类似的东西 ;）
