Spring Rest Repository Error

Question

在Repositories中的Rest Spring API中，我需要通過三個參數來查找值，但這是phone，password，找到delete = 0。我已經將它添加到實體，但它顯示錯誤無效的派生查詢！找不到類型爲CustomerEntity的屬性！兩個現場工作正常，但刪除的工作不

@Repository 
public interface CustomerRepository extends JpaRepository<CustomerEntity, Long> { 
CustomerEntity findByfacebookID(String facebookID); 
CustomerEntity findByPhoneAndPasswordAndIsDeleted(String phone, String password, Boolean isdeleted); 

實體

@Entity 
@Table(name = "CUSTOMER") 
public class CustomerEntity { 

    @Column(name = "IS_DELETED", length = 3, nullable = false) 
    private Boolean isdeleted; 

Answer 1

春數據JPA假定您的字段名稱遵循一定的約定，以便正確地生成導出查詢。資本化問題; isdeleted != isDeleted。此外，IsXYZ在Spring Data JPA查詢中有special meaning，並且可能會導致語法歧義。在一般情況下，墨守成規，事情就會簡單得多：

@Repository 
public interface CustomerRepository extends JpaRepository<CustomerEntity, Long> { 
    CustomerEntity findByfacebookID(String facebookID); 

    CustomerEntity findByPhoneAndPasswordAndDeleted(String phone, String password, Boolean deleted); 
} 

@Entity 
@Table(name = "CUSTOMER") 
public class CustomerEntity { 

    @Column(name = "IS_DELETED", length = 3, nullable = false) 
    private Boolean deleted; 

    // phone, password, other fields... 
} 

簡而言之：從你的布爾變量刪除is前綴（即通常在訪問的方法名稱中使用，而不是在字段名稱）。
