错误描述

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.

出错场景

Spring工具类静态注入一个Request作用域的bean

/**
 * 张俊杰 2023年05月06日14:21:21
 */
public class TraceIdUtil {

    private static TraceIdGenerator traceIdGenerator;



    public static String getTraceId() {
        return traceIdGenerator.getTraceId();
    }

    public static void setTraceIdGenerator(TraceIdGenerator traceIdGenerator) {
        TraceIdUtil.traceIdGenerator = traceIdGenerator;
    }

}

import cn.hutool.core.lang.UUID;

/**
 * 张俊杰 2023年05月06日14:21:21
 */
public class TraceIdGenerator {

    private String traceId = UUID.randomUUID().toString();


    public String getTraceId() {
        return this.traceId;
    }

}

    <bean id="traceIdGenerator" class="com.iph.hiring.headcount.util.TraceIdGenerator" scope="request">
<!--       之前是没加下面这个东西,就报错了, 添加个 <aop:scoped-proxy/> 就不报错了. -->
<!--         <aop:scoped-proxy/> -->
    </bean>
    <bean id="traceIdUtil" class="com.iph.hiring.headcount.util.TraceIdUtil">
        <property name="traceIdGenerator" ref="traceIdGenerator"/>
    </bean>

解决思路

参考: https://blog.csdn.net/qq_36951116/article/details/79121887
request bean那边配置添加个 aop:scoped-proxy/ 标签文章来源地址https://www.toymoban.com/news/detail-717447.html

    <bean id="traceIdGenerator" class="com.iph.hiring.headcount.util.TraceIdGenerator" scope="request">
        <aop:scoped-proxy/>
    </bean>
    <bean id="traceIdUtil" class="com.iph.hiring.headcount.util.TraceIdUtil">
        <property name="traceIdGenerator" ref="traceIdGenerator"/>
    </bean>
