AbstractMethodError

[qiqi5526]

I got a AbstractMethodError when I call DashScope Chat Model for getting keyword of a document

the code like below

` public static void main(String[] args) {

    DashScopeApi dashScopeApi = new DashScopeApi("7777777777");
    DashScopeChatOptions options = DashScopeChatOptions.builder()
            .withModel("qwen2-vl-7b-instruct")
            .withTemperature(0.7f)
            .build();
    DashScopeChatModel chatModel = new DashScopeChatModel(dashScopeApi,options);// initialize your chat model
    KeywordMetadataEnricher enricher = new KeywordMetadataEnricher(chatModel, 5);

    Document doc = new Document("This is a document about artificial intelligence and its applications in modern technology.");

    List<Document> enrichedDocs = enricher.apply(List.of(doc));

    Document enrichedDoc = enrichedDocs.get(0);
    String keywords = (String) enrichedDoc.getMetadata().get("excerpt_keywords");
    System.out.println("Extracted keywords: " + keywords);
}`

the exception as:

my pom:

I also encountered the same problem and later discovered that in spring-ai-alibaba-core-1.0-02.1. jar, There is no getToolContext method in the com.alibaba.cloud.ai.dashscope.chat.DashScopeChatOptionsclass.
