在实体类中使用MultiField注释以用于弹性搜索

Question

我目前使用Spring boot 2.7.0和Spring data elastic search 4.4.0 with ELK 7.17.4。在使用多字段注释时有问题。得到一个MappingException，但是注释已经被正确使用。Annotation定义和Validation代码都是Spring数据弹性搜索4.4.0的一部分，因此这里存在冲突。

有一个实体类:

@MultiField(mainField = @Field(type = FieldType.Text, fielddata = true, analyzer = LOWER_KEYWORD_ANALYZER, searchAnalyzer = LOWER_KEYWORD_ANALYZER),
otherFields = {
@InnerField(suffix = "sort", type = FieldType.Keyword, index = false),
@InnerField(suffix = "raw", type = FieldType.Keyword, index = false)
})
private Set<String> myProp = new HashSet<>();
```

Getting an error:
Caused by: org.springframework.data.mapping.MappingException: @Field annotation must not be used on a @MultiField property
Error stack trace:
Caused by: org.springframework.data.mapping.MappingException: @Field annotation must not be used on a @MultiField property.

Answer 1

当你有一个@MultiField和时抛出这个异常同一属性上的@Field注释。可惜你没有显示完整的实体类。
