如何使用最新的 spring-boot 在 jpa 测试中使用 where 子句计算记录?
How to count records with where clause in jpa test with latest spring-boot?
我有 UserRepository:
public interface UserRepository extends JpaRepository<User, String> {}
实体:
@Entity
@Table(schema="test", name = "TBL_USERS")
@Builder
@AllArgsConstructor
public class User implements Persistable<String> {
@Id
@Column(name = "ID", columnDefinition = "char")
private String id;
@NotNull
@Column(name = "NAME", columnDefinition = "char", nullable = false)
private String name;
...
}
在我的测试中,我想计算具有特定名称的记录,如查询:
select count(*) from TBL_USERS where name='John';
@Test
public void testCountSimilarNames() {
...
userRepository.count() ... ?
}
我使用最新的spring-boot。
你需要这样的东西:
public interface UserRepository extends CrudRepository<User , String >{
Integer countByName(String name);
}
