一、错误分析
做品优购项目的运营商安全登录时，运行项目后，浏览器访问模板页，模板页的表格无法正常显示，报错信息如下：
java

at java.lang.Thread.run(Thread.java:748)访问页面失败：
提取关键信息：
javajava.lang.IllegalStateException: No ConfigurableListableBeanFactory set根据上述错误，可能是因为缺少了ConfigurableListableBeanFactory的配置，定位到springmvc.xml文件
二、代码修改
springmvc.xml文件修改前：
XML
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://code.alibabatech.com/schema/dubbo
http://code.alibabatech.com/schema/dubbo/dubbo.xsd
http://www.springframework.org/schema/context

<mvc:annotation-driven>
<mvc:message-converters register-defaults="true">
<bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
<property name="supportedMediaTypes" value="application/json"/>
<property name="features">

<value>WriteMapNullValue</value>
<value>WriteDateUseDateFormat</value>
</array>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!-- 引用dubbo 服务 -->
<dubbo:application name="pinyougou-manager-web" />
<dubbo:registry address="zookeeper://192.168.25.139:2181"/>
<dubbo:annotation package="com.pinyougou.manager.controller" />
</beans>springmvc.xml文件修改后：
XML
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<mvc:message-converters register-defaults="true">

<property name="supportedMediaTypes" value="application/json"/>
<property name="features">

<value>WriteDateUseDateFormat</value>
</array>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<!-- 引用dubbo 服务 -->
<dubbo:application name="pinyougou-manager-web" />
<dubbo:registry address="zookeeper://192.168.25.139:2181"/>
<dubbo:annotation package="com.pinyougou.manager.controller" />
<context:annotation-config/>
</beans>在代码中添加了
<context:annotation-config/>，这样可以确保ConfigurableListableBeanFactory正确配置
再次运行代码，正常访问页面
三、 怎么知道代码改哪里
目前在用chatgpt网站：AIGC+ (aigcplus.io)
把错误信息和要修改的代码贴上，直接问它，"请根据上述错误修改下列代码"，即可得到较为正确的修改方向
