java - Spring Filter - 如果调用了无效路由，则“未找到线程绑定请求”

Question

我想Correlation-Id使用 Spring 过滤器为所有响应添加标头。到目前为止它工作得很好，但是如果我调用与资源不匹配的路由，我会遇到java.lang.IllegalStateException异常。

我的过滤器如下所示：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.UUID;

public class AttachCorrelationIdHeaderFilter extends OncePerRequestFilter {
    private static final Logger LOGGER = LoggerFactory.getLogger(AttachCorrelationIdHeaderFilter.class);

    private String correlationIdHeaderName = "";

    public AttachCorrelationIdHeaderFilter(String correlationIdHeaderName) {
        this.correlationIdHeaderName = correlationIdHeaderName;
    }

    @Override
    protected void doFilterInternal(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, FilterChain filterChain) throws ServletException, IOException {
        String correlationId = httpServletRequest.getHeader(this.correlationIdHeaderName);

        if (correlationId == null || correlationId.isEmpty()) {
            correlationId = UUID.randomUUID().toString();
            LOGGER.debug("Generated new Correlation-Id {}", correlationId);
        } else {
            LOGGER.debug("Use existing Correlation-Id {}", correlationId);
        }

        httpServletResponse.addHeader(this.correlationIdHeaderName, correlationId);

        filterChain.doFilter(httpServletRequest, httpServletResponse);
    }
}

并将在一个简单的配置类中注册：

import *.AttachCorrelationIdHeaderFilter;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class CorrelationConfiguration {
    private String correlationIdHeaderName;

    public CorrelationConfiguration(@Value("${usagebox-scs.headers.correlation-id}") String correlationIdHeaderName) {
        this.correlationIdHeaderName = correlationIdHeaderName;
    }

    @Bean
    public FilterRegistrationBean attachCorrelationIdFilter() {
        final FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean<AttachCorrelationIdHeaderFilter>();
        final AttachCorrelationIdHeaderFilter attachCorrelationIdFilter = new AttachCorrelationIdHeaderFilter(correlationIdHeaderName);

        filterRegistrationBean.setFilter(attachCorrelationIdFilter);
        filterRegistrationBean.setOrder(-1);
        return filterRegistrationBean;
    }
}

异常如下所示：

java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.
