Spring Rest Repository Error

Question

在Repositories中的Rest Spring API中，我需要通过三个参数来查找值，但这是phone，password，找到delete = 0。我已经将它添加到实体，但它显示错误无效的派生查询！找不到类型为CustomerEntity的属性！两个现场工作正常，但删除的工作不

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

实体

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

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

Answer 1

春数据JPA假定您的字段名称遵循一定的约定，以便正确地生成导出查询。资本化问题; isdeleted != isDeleted。此外，IsXYZ在Spring Data JPA查询中有special meaning，并且可能会导致语法歧义。在一般情况下，墨守成规，事情就会简单得多：

@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... 
} 

简而言之：从你的布尔变量删除is前缀（即通常在访问的方法名称中使用，而不是在字段名称）。
