对于在service层使用RequestContextHolder的方法要小心，除了controller层外，调度任务等也可能调用service层的方法。

分析

该错误信息在RequestContextHolder这个类中，详细如下：
spring-web-4.3.7.RELEASE-sources.jar!/org/springframework/web/context/request/RequestContextHolder.java

public abstract class RequestContextHolder  {

    private static final boolean jsfPresent =
            ClassUtils.isPresent("javax.faces.context.FacesContext", RequestContextHolder.class.getClassLoader());

    private static final ThreadLocal<RequestAttributes> requestAttributesHolder =
            new NamedThreadLocal<RequestAttributes>("Request attributes");

    private static final ThreadLocal<RequestAttributes> inheritableRequestAttributesHolder =
            new NamedInheritableThreadLocal<RequestAttributes>("Request context");

    /**
     * Return the RequestAttributes currently bound to the thread.
     * <p>Exposes the previously bound RequestAttributes instance, if any.
     * Falls back to the current JSF FacesContext, if any.
     * @return the RequestAttributes currently bound to the thread
     * @throws IllegalStateException if no RequestAttributes object
     * is bound to the current thread
     * @see #setRequestAttributes
     * @see ServletRequestAttributes
     * @see FacesRequestAttributes
     * @see javax.faces.context.FacesContext#getCurrentInstance()
     */
    public static RequestAttributes currentRequestAttributes() throws IllegalStateException {
        RequestAttributes attributes = getRequestAttributes();
        if (attributes == null) {
            if (jsfPresent) {
                attributes = FacesRequestAttributesFactory.getFacesRequestAttributes();
            }
            if (attributes == null) {
                throw new 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.");
            }
        }
        return attributes;
    }

    /**
     * Return the RequestAttributes currently bound to the thread.
     * @return the RequestAttributes currently bound to the thread,
     * or {@code null} if none bound
     */
    public static RequestAttributes getRequestAttributes() {
        RequestAttributes attributes = requestAttributesHolder.get();
        if (attributes == null) {
            attributes = inheritableRequestAttributesHolder.get();
        }
        return attributes;
    }

    //...
}

解决

在非web下访问了RequestContextHolder.currentRequestAttributes()导致，因此在service层方法里头调用该方法要慎重，为了避免出错，可以再封装一下

package com.yzy.common.core.interceptors;

import cn.hutool.core.util.StrUtil;
import com.yzy.common.constant.AuthConstant;
import com.yzy.common.core.local.LocalUser;
import com.yzy.common.core.local.UserIdentityBO;
import feign.RequestInterceptor;
import feign.RequestTemplate;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;

/**
 * 当拿不到request时，创建NonWebRequestAttributes来实现RequestAttributes，然后加一个非空判断绕过强转的地方，这样就能正常的调用其他服务了
 */
public class FeignRequestHeaderInterceptor implements RequestInterceptor {
    public FeignRequestHeaderInterceptor(){

    }

    @Override
    public void apply(RequestTemplate requestTemplate) {
    //修改前
//        RequestAttributes requestAttributes =  RequestContextHolder.currentRequestAttributes();
//修改后
        HttpServletRequest httpServletRequestSafely = getHttpServletRequestSafely();
        
        if (httpServletRequestSafely != null) {
            HttpServletRequest request = ((ServletRequestAttributes) httpServletRequestSafely).getRequest();
            requestTemplate.header(AuthConstant.USER_TOKEN_HEADER, request.getHeader(AuthConstant.USER_TOKEN_HEADER));
        }
        UserIdentityBO userIdentityBO = LocalUser.getLocalUser();
        if (userIdentityBO==null){
            return;
        }
        if(!StrUtil.isEmpty(userIdentityBO.getScope())){
            requestTemplate.header(AuthConstant.CURRENT_SCOPE, userIdentityBO.getScope());
        }
        if (null != userIdentityBO.getUid() && 0 != userIdentityBO.getUid()) {
            requestTemplate.header(AuthConstant.CURRENT_USER, String.valueOf(userIdentityBO.getUid()));
        }
        if(null != userIdentityBO.getIdentity() ){
            requestTemplate.header(AuthConstant.CURRENT_IDENTITY, String.valueOf(userIdentityBO.getIdentity()));
        }
    }

    public HttpServletRequest getHttpServletRequestSafely() {
        try {
            RequestAttributes requestAttributesSafely = this.getRequestAttributesSafely();
            return requestAttributesSafely instanceof NonWebRequestAttributes ? null : ((ServletRequestAttributes)requestAttributesSafely).getRequest();
        } catch (Exception var2) {
            return null;
        }
    }

    public RequestAttributes getRequestAttributesSafely() {
        Object requestAttributes = null;

        try {
            requestAttributes = RequestContextHolder.currentRequestAttributes();
        } catch (IllegalStateException var3) {
            requestAttributes = new NonWebRequestAttributes();
        }

        return (RequestAttributes)requestAttributes;
    }

}

NonWebRequestAttributes实现RequestAttributes接口，重写的方法都为空即可

NonWebRequestAttributes

package com.yzy.common.core.interceptors;

import org.springframework.web.context.request.RequestAttributes;

public class NonWebRequestAttributes implements RequestAttributes {
    @Override
    public Object getAttribute(String s, int i) {
        return null;
    }

    @Override
    public void setAttribute(String s, Object o, int i) {

    }

    @Override
    public void removeAttribute(String s, int i) {

    }

    @Override
    public String[] getAttributeNames(int i) {
        return new String[0];
    }

    @Override
    public void registerDestructionCallback(String s, Runnable runnable, int i) {

    }

    @Override
    public Object resolveReference(String s) {
        return null;
    }

    @Override
    public String getSessionId() {
        return null;
    }

    @Override
    public Object getSessionMutex() {
        return null;
    }
}
