SpringBoot对接口请求参数（@RequestBody 和 @ Request Param）进行解密过滤

 

 

/**
 * @Description: 拦截所有请求过滤器，并将请求类型是HttpServletRequest类型的请求替换为自定义
 */

@javax.servlet.annotation.WebFilter(filterName = "WebFilter", urlPatterns = "/*")
public class WebFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain chain)
            throws IOException, ServletException {
        ServletRequest request = null;
　　　　　//此处分别处理POST请求（Body）和GET请求（Parameter）
        if (servletRequest instanceof HttpServletRequest) {
            if(((HttpServletRequest) servletRequest).getMethod().equals("POST")){
                request = new BodyRequestWrapper((HttpServletRequest) servletRequest);
            }else if(((HttpServletRequest) servletRequest).getMethod().equals("GET")){
                request = new ParameterRequestWrapper((HttpServletRequest) servletRequest);
            }
        }
        if (request == null) {
            chain.doFilter(servletRequest, servletResponse);
        } else {
            chain.doFilter(request, servletResponse);
        }
    }

    @Override
    public void destroy() {
    }
}
