如何在 Elasticsearch 中将高度信息存储为浮点数

Question

如何在spring-data-elasticsearch 中将高度信息存储为浮点数。我的数据模型如下所示

Height.java
    int feet, inches;

@Document(indexName = "users", shards = 1, versionType = VersionType.INTERNAL, createIndex = true)
public class User implements Persistable<String> {
    private Height height;
}

Answer 1

FloatConverter 似乎可以工作

@WritingConverter
public enum ToFloatConverter implements Converter<Height, Float> {

    INSTANCE;

    @Override
    public Float convert(Height height) {
        String heightStr = height.getFeet() + "." + height.getInches();
        return Float.parseFloat(heightStr);
    }
}
