測試結果

補充：

• 阿里云api注冊以及使用：官網
• 兩個報錯
  網頁漏看路徑：Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. Mon Jun 16 23:09:14 CST 2025 There was an unexpected error (type=Not Found, status=404).
  環境配置版本問題
• Consider defining a bean of type 'dev.langchain4j.community.model.dashscope.QwenChatModel
• dev.langchain4j:langchain4j-community-dashscope-spring-boot-starter:jar:unknown was not found in https://maven.aliyun.com/nexus/content/groups/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of alimaven has elapsed or updates are forced
