更改Request Parameters中的值

1. 定义ParameterRequestWrapper 继承HttpServletRequestWrapper

?

public void doFilter(ServletRequest request, ServletResponse response,FilterChain chain) throws IOException, ServletException {HttpServletRequest httpRequest = (HttpServletRequest) request;Map<String, String[]> parametersMap = DataFormat.formatRequestParameters(httpRequest);ParameterRequestWrapper requestWrapper = new ParameterRequestWrapper(httpRequest, parametersMap);chain.doFilter(requestWrapper, response);}
