Question

我试图使用Spring-El传递多个In Clause参数，我的查询是：

@Query(nativeQuery = true, value = "select a.* from ACC a where (a.iban, a.currency) in (:#{#ibanAccounts.accountNumber} , :#{#ibanAccounts.currency})")
    List<ACC> getAccount(@Param("ibanAccounts") List<AccountDetails> ibanAccounts);

但我收到了以下错误：

EL1008E:(pos 14): Property or field 'accountNumber' cannot be found on object of type 'java.util.ArrayList$SubList' - maybe not public? 
org.springframework.expression.spel.SpelEvaluationException: EL1008E:(pos 14): Property or field 'accountNumber' cannot be found on object of type 'java.util.ArrayList$SubList' - maybe not public?

    at org.springframework.expression.spel.ast.SpelNodeImpl.getTypedValue(SpelNodeImpl.java:131)

在AccountDetails中，该字段与public getter一起出现。

任何人都可以指导我说错了吗？

Answer 1

我相信你要找的是collection projection。

所以你需要使用这样的东西

@Query(nativeQuery = true, value = "select a.* from ACC a where (a.iban, a.currency) in :#{#ibanAccounts.![accountNumber]} , :#{#ibanAccounts.currency})")
List<ACC> getAccount(@Param("ibanAccounts") List<AccountDetails> ibanAccounts);

在SPEL的子句参数中
