我已使用以下代码实现了“每个请求过滤器一次”：
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException
{
httpRequestWrapper = Optional.ofNullable(new HttpRequestWrapper(request));
if(httpRequestWrapper.isPresent())
{
Message message = objectMapper.readValue(httpRequestWrapper.get().getInputStream(), Message.class);
try
{
boolean isAuthenticatedHeader = false;
RabbitMq.rabbitMqLog(canonicalMessage);
isAuthenticatedHeader = authenticateAuthHeader(request.getHeader(Constants.AUTH), request.getHeader(Constants.PASS));
if (isAuthenticatedHeader)
{
Logger.logInfo(new LogDetails(CLASSNAME), "Aunthentication successful !!!! ");
if (Filter.isInValid().test(canonicalMessage))
{
throw new BadRequestException();
}
}
else
{
Logger.logError(new LogDetails(CLASSNAME), " Aunthentication not successful. Please check. ");
throw new NotAuthorizedException("Unauthorized Access");
}
Map<String, String> headers = Collections.list(((HttpServletRequest) request).getHeaderNames()).stream().collect(Collectors.toMap(h -> h, request::getHeader));
headers.updateHeaders(headers);
filterChain.doFilter(httpRequestWrapper.get(), response);
RabbitMq.rabbitMqLog();
}
catch (Exception e)
{}
}
}
tomcat启动后，我就处于异常之下：

我尝试了以下操作：
if (request.getMethod().equals("POST") && (new AntPathRequestMatcher("/transactions/v1/enrichments").matches(request))) {
httpRequestWrapper = Optional.ofNullable(new HttpRequestWrapper(request));
if(httpRequestWrapper.isPresent())
{
CanonicalMessage canonicalMessage = objectMapper.readValue(httpRequestWrapper.get().getInputStream(), CanonicalMessage.class);
try
{
boolean isAuthenticatedHeader = false;
eventLogRawDataServiceImpl.eventLogExecution(canonicalMessage);
isAuthenticatedHeader = authenticateAuthHeader(request.getHeader(Constants.AUTHORIZATION), request.getHeader(Constants.DEPLOYMENT_TOKEN));
if (isAuthenticatedHeader)
{
ondotLogger.logInfo(new LogDetails(CLASSNAME), "Aunthentication successful !!!! ");
if (CloudServerFilter.isInValid().test(canonicalMessage))
{
throw new BadRequestException();
}
}
else
{
ondotLogger.logError(new LogDetails(CLASSNAME), " Aunthentication not successful. Please check. ");
throw new NotAuthorizedException("Unauthorized Access");
}
Map<String, String> headers = Collections.list(((HttpServletRequest) request).getHeaderNames()).stream().collect(Collectors.toMap(h -> h, request::getHeader));
cloudServerHeaders.updateHeaders(headers);
filterChain.doFilter(httpRequestWrapper.get(), response);
responseHandler.eventLoggerForResponse();
}
catch (Exception e)
{}
}
}else
{
filterChain.doFilter(request, response);
}
还有这个
@Configuration
public class CloudServerConfigAdapter extends WebMvcConfigurerAdapter{
@Autowired
private Filter filter;
@Bean
public FilterRegistrationBean myFilterRegistrationBean() {
FilterRegistrationBean regBean = new FilterRegistrationBean();
regBean.setFilter(filter);
regBean.setOrder(1);
regBean.addUrlPatterns("/transactions/v1/enrichments");
return regBean;
}
}
例外：
