Spring Data JPA检查SET是否包含对象

Question

我有一个名为Device的域对象，具有此属性

@ManyToMany(cascade = CascadeType.MERGE, fetch = FetchType.EAGER)
private Set<Driver> authorizedDrivers = new HashSet<>();

我想进行此查询，但我收到错误（antlr.NoViableAltException：意外AST节点:(）

@Query("select dev from Device dev where dev.authorizedDrivers.contains(?1) ")
Set<Device> findDeviceByDriver(Driver driver);

Answer 1

JPQL没有＆＃39;包含＆＃39;表达。您可以尝试此查询：

@Query("select dev from Device dev join dev.authorizedDrivers d where d = ?1")
Set<Device> findDeviceByDriver(Driver driver);
