我有兩個物體，Search并且Amount我正在以這種方式使用 Hibernate Search 進行映射：
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Builder
@ToString
@Entity
@Indexed
public class Search extends SearchableItem {
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "SEARCH_SEQ")
@DocumentId
private Long id;
@Embedded
@Valid
@IndexedEmbedded
private Amount maxAmount;
@Embedded
@Valid
@IndexedEmbedded
private Amount minAmount;
}
@Getter
@Setter
@NoArgsConstructor
@AllArgsConstructor
@Builder
@ToString
@Embeddable
public class Amount {
@NotNull
@ScaledNumberField(sortable = Sortable.YES)
private BigDecimal value;
@NotNull
@Enumerated(EnumType.STRING)
@GenericField
private CurrencyCode currency;
}
這些注釋以這種方式在 Elasticsearch 上創建我的索引：
{
"search-000001": {
"aliases": {
"search-read": {
"is_write_index": false

"search-write": {

}
對于 Elasticsearch 上的搜索，我使用了一個自定義評分函式，它嘗試訪問搜索檔案中的 minAmount 和 maxAmount 物件，但我收到此錯誤：
Unhandled Exception illegal_argument_exception
No field found for [maxAmount] in mapping
Stack:
[
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:100)",
"org.elasticsearch.search.lookup.LeafDocLookup.get(LeafDocLookup.java:28)",
"score = calculateScoreAmount(doc.maxAmount, doc.minAmount, params);\n ",
" ^---- HERE"
]
我過去在其他物體上遇到過同樣的問題，@GenericField(sortable = Sortable.YES)我在分數腳本中指定我需要訪問的屬性解決了它（請注意，如果沒有明確的 Sortable.YES，我在腳本評分函式執行期間收到了來自 Elasticsearch 的錯誤）。這里的問題是這Amount是一個自定義物件，@GenericField(sortable = Sortable.YES)不能在其上指定。
有人可以幫忙嗎？
uj5u.com熱心網友回復：
maxAmount是一個物件欄位。通過 檢索其值是沒有意義的doc.maxAmount，因為此語法用于訪問 doc 值，并且物件欄位不在 doc 值中表示。
我不確定您的腳本是什么，或者您將它傳遞給 Elasticsearch 的位置，但問題可能就在那里。
如果您想訪問maxAmount.value/的檔案值minAmount.value，那么您可能應該替換calculateScoreAmount(doc.maxAmount, doc.minAmount, params);為calculateScoreAmount(doc['maxAmount.value'].value, doc['minAmount.value'].value, params);
如果要訪問表示maxAmount/的 JSON 物件minAmount，則不應使用 docvalues，而應使用_source: calculateScoreAmount(ctx._source.maxAmount, ctx._source.minAmount, params);。我不確定這種語法是否完全正確，因為我找不到任何檔案來訪問源代碼，但它應該接近這個。另外，請記住，如果您有很多檔案，這會很慢。
