how to use specific fields:

@Column(name = "password")
@NotBlank(message = "!")
@Length(min = 3, max = 6)
@ColumnTransformer(
        write = "HEX(AES_ENCRYPT(?, "password"))",
        read = "AES_DECRYPT(UNHEX(password),"password")"
)
private String adminPassword;

@ Repository
public interface AdminRepository extends JpaRepository < Admin, Integer >, JpaSpecificationExecutor < Admin > {

public class AdminController {

/**

    return adminRepository.saveAndFlush(admin);
}

/**

 */
@GetMapping("/findById/{adminId}")
public Optional<Admin> findAdminById(@PathVariable(value = "adminId") int id) {
    return adminRepository.findById(id);
}


what result do you expect? What is the error message actually seen?

create an administrator:

id3:

idea log printing:
Hibernate: select admin0_.id as id1_0_0_, admin0_.lastModTime as lastModT2_0_0_, admin0_.name as name3_0_0_, AES_DECRYPT (UNHEX (admin0_.password), "admin0_.password") as password4_0_0_, admin0_.phone as phone5_0_0_, admin0_.regTime as regTime6_0_0_, admin0_.status as status7_0_0_ Admin0_.username as username8_0_0_ from WINES_ADMIN admin0_ where admin0_.id=?

should return the password of sdfsd, but the result is null.

look forward to God"s help!


Try to add the forcolumn value to the

@ ColumnTransformer note

@Column(name = "password")
@NotBlank(message = "!")
@Length(min = 3, max = 6)
@ColumnTransformer(
        forColumn = "password",
        write = "HEX(AES_ENCRYPT(?, 'password'))",
        read = "AES_DECRYPT(UNHEX(password),'password')"
)
private String adminPassword;

current data operations are based on hibernate

HEX(AES_ENCRYPT(?, 'password'))

password in this code is encrypted salt bar.

from a security point of view, set the encryption salt to the environment variable.
