Question

我想要映射@CompletionField之类的Entity中的字段，但是具有上下文，因为现在Completion包含String []和int weight字段。我想过滤索引中的完成。

@Document(indexName = "compl_index")
    public class ComplIndex {
    @CompletionField
    private Completion suggestions;
   }

当我编写此类时，我对字符串数组和权重有一个简单的完成，但是我想像这样映射实体并使用上下文。我尝试解决此问题-使用字段类型，上下文等编写新实体，并使用Mapping，CompletionFieldMapper抛出异常“字段不支持上下文字段：...

"name": {
          "type": "completion",
          "contexts": [
            {
              "name": "year",
              "type": "category",
              "path": "year"
            }
          ]
        },
        "year": {
          "type": "text"
        }

它已经受支持，您可以在DATAES-536上找到示例。对于较低版本，您需要编写一个自定义完成模型，并使用@Mapping字段而不是@CompletionField。

public class CustomCompletion {

    private String[] input;
    private Map<String, List<String>> contexts;
    private Integer weight;

    private CustomCompletion() {
        // required by mapper to instantiate object
    }

    public CustomCompletion(String[] input) {
        this.input = input;
    }

    // Setter getter

}

@Document(indexName = "compl_index")
public class ComplIndex {

    @Mapping(mappingPath = "/mapping/compl-index-suggestions.json")
    private CustomCompletion suggestions;

}

compl-index-suggestions.json

{
  "type": "completion",
  "contexts": [
    {
      "name": "year",
      "type": "category"
    }
  ]
}

在spring-data-elasticsearch中是否可以将Context字段与Context Recommendationer映射？
