回答不易，求求您点赞采纳哦

看起来您遇到了 Spring Web 应用程序错误，特别是“多部分 HttpMessageReader”错误。

您提供的错误消息表示IllegalStateException已抛出消息“No multipart HttpMessageReader”。当应用程序尝试为请求初始化多部分数据，但没有HttpMessageReader可用于处理多部分数据时，将抛出此异常。

要解决此问题，您可以尝试以下操作：

  • 检查应用程序的日志文件是否有任何其他错误消息或警告可能提供有关问题原因的更多信息。

  • 确保您的应用程序中安装了必要的依赖项和库以支持多部分数据。

  • 检查应用程序的配置以确保其设置正确并且多部分数据设置没有问题。

  • 尝试重现错误并捕获网络跟踪或请求/响应数据，以查看它是否提供了有关问题原因的任何线索。
