我正在使用Spring JPA通過Hibernate與Progress OpenEdge數據庫進行通信。一切正常，但現在我試圖使用PagingAndSortingRepository中的findAll（Iterable ID）方法從數據庫中獲取ItemDescription對象的選定列表，並且它似乎不起作用...org.springframework.dao.InvalidDataAccessApiUsageException當使用findAll（Iterable <ID> ID）方法
這是我的ItemDescription型號：
@Entity
@Table(name = "ArtOmsPAD", catalog = "MSOFTDB", schema = "PUB")
@IdClass(ItemDescriptionPK.class)
public class ItemDescription implements Serializable
{
private static final long serialVersionUID = 1L;
@Size(max = 10)
@Column(name = "ArtGrp", length = 10)
@Id
private String itemGroup;
@Size(max = 70)
@Column(name = "ArtSymb", length = 70)
@Id
private String itemSymbol;
@Size(max = 4)
@Column(name = "Taal", length = 4)
@Id
private String language;
@Size(max = 400)
@Column(name = "Oms", length = 400)
private String description;
@Column(name = "record_crc", precision = 17, scale = 2)
private BigDecimal recordCrc;
... (Getters/Setters)
}
而我的ID類...
public class ItemDescriptionPK implements Serializable
{
private String itemGroup;
private String itemSymbol;
private String language;
public ItemDescriptionPK()
{
}
public ItemDescriptionPK(String pItemGroup,
String pItemSymbol,
String pLanguage)
{
this.itemGroup = pItemGroup;
this.itemSymbol = pItemSymbol;
this.language = pLanguage;
}
... (Hashcode/Equals)
}
而服務類：
@Service("ItemDescriptionService")
public class ItemDescriptionService
{
@Autowired
private IItemDescriptionRepository itemDescriptionRepository;
public Iterable<ItemDescription> findAll(Iterable<ItemDescriptionPK> pItemDescriptionPK)
{
return itemDescriptionRepository.findAll(pItemDescriptionPK);
}
... (findOne method)
}
我建立與IDS因爲我想讀這樣的所有ItemDescription對象列表（這是在ReceiptDetail服務類...）：
for (ReceiptDetail oReceiptDetail : lReceiptDetail)
{
oItemDescriptionPK = new ItemDescriptionPK(oReceiptDetail.getItemGroup(),
oReceiptDetail.getItemSymbol(),
vLanguage);
lItemDescriptionPK.add(oItemDescriptionPK);
}
事後我使用下面的代碼實際上閱讀ItemDescription對象：
itemDescriptionService.findAll(lItemDescriptionPK);
但是，這在執行時，我得到以下異常和堆棧跟蹤：
org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [MSoftServlet] in context with path [/Receipt] threw exception [Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value element [itemGroup=12010,itemSymbol= 80 10100 -04 -000 -000,language=N] did not match expected type [java.lang.String (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value element [itemGroup=12010,itemSymbol= 80 10100 -04 -000 -000,language=N] did not match expected type [java.lang.String (n/a)]] with root cause

如果我正確理解異常，我會認爲我的ItemDescriptionPK類中的某個元素具有錯誤的數據類型，但我沒有看到它的任何錯誤... ID的所有三個部分都被定義爲String（否則I如果有人可以告訴我我做錯了什麼，或者可以給我的指示我可以嘗試通過這個異常，我會是gratefull。就像旁邊一樣......因爲我只是在爲這個項目學習Java，所以我們仍然感覺我們的方法如此變化/方法/ ......根據最佳實踐，命名可能並不完整。這是我們仍然在我們的TODO名單上。
由於提前，

嗯，我必須將我的Id類中的字段映射到對象類中的相應字段不？ findAll方法需要一個ItemDescriptionPK對象的迭代器作爲輸入參數，並且它會得到這些對象的一個列表（據我所知，它可以轉換爲一個迭代器）。有沒有辦法讓這個工作以某種方式？ – HeinoVDS 2014-09-30 12:24:41
在您定義的組合鍵類型的類中創建一個字段。將itemGroup字符串中的@Id註釋更改爲新字段。 – 2014-09-30 12:36:51
好吧，這似乎是或多或少工作...如果我的ItemDescriptionRepository中有一個findBy，它使用了我的模型的一些關鍵字段，這不再有效（在我的情況下，我有一個findByItemGroupAndItemSymbol）。這些字段在模型中不再可用，但移動到PK類，現在我得到一個錯誤，說明該方法無法生成。所以，我想我以前的評論中的問題應該是，有沒有辦法讓這個工作，而不刪除在findBy方法中使用這些字段的選項？ – HeinoVDS 2014-09-30 14:22:17
