一、錯誤分析?
做品優購項目的運營商安全登錄時，運行項目后，瀏覽器訪問模板頁，模板頁的表格無法正常顯示，報錯信息如下：
SEVERE: StandardWrapper.Throwable

訪問頁面失敗：
?
提取關鍵信息：
java.lang.IllegalStateException: No ConfigurableListableBeanFactory set根據上述錯誤，可能是因為缺少了ConfigurableListableBeanFactory的配置，定位到springmvc.xml文件
二、代碼修改?
springmvc.xml文件修改前：
<?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/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://code.alibabatech.com/schema/dubbohttp://code.alibabatech.com/schema/dubbo/dubbo.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsd"><context:property-placeholder location="classpath:config/application.properties" /><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"><array><value>WriteMapNullValue</value><value>WriteDateUseDateFormat</value></array></property></bean></mvc:message-converters> </mvc:annotation-driven><!-- 引用dubbo 服務 --><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：
<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/beanshttp://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/mvchttp://www.springframework.org/schema/mvc/spring-mvc.xsdhttp://code.alibabatech.com/schema/dubbohttp://code.alibabatech.com/schema/dubbo/dubbo.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-4.0.xsd"><context:property-placeholder location="classpath:config/application.properties" /><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"><array><value>WriteMapNullValue</value><value>WriteDateUseDateFormat</value></array></property></bean></mvc:message-converters></mvc:annotation-driven><!-- 引用dubbo 服務 --><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>
在代碼中添加了
<context:annotation-config/>，這樣可以確保ConfigurableListableBeanFactory正確配置?
?再次運行代碼，正常訪問頁面
三、 怎么知道代碼改哪里
目前在用chatgpt網站：AIGC+ (aigcplus.io)
把錯誤信息和要修改的代碼貼上，直接問它，“請根據上述錯誤修改下列代碼”，即可得到較為正確的修改方向?
