建议你添加一下

同学你好！

要在spring-web.xml中配置文件上传解析器，否则后台获取不到数据，具体代码

<!-- 文件上传解析器 -->
<bean id="multipartResolver"
   class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
 <property name="defaultEncoding" value="utf-8"></property>
 <!-- 1024 * 1024 * 20 = 20M -->
 <property name="maxUploadSize" value="20971520"></property>
 <property name="maxInMemorySize" value="20971520"></property>
</bean>

同学你好！

这个问题可能的原因：

1. 在浏览器控制台检查一下数据是否都正确提交了

   
   

2. 打断点，查看一下后台是否能够获取到验证码seesion中的验证码，以及request的数据是不是下图所示的样子，并检查一下页面的验证码是否获取到了

   
   

3. 配置文件中文件上传的bean是否写错了

   

祝学习愉快~
