JPA ColumnTransformer write is not working - spring-boot

Question

this is my entity.
#Getter
#Setter
#Entity
#Table(name = "crypt_test_table")
#IdClass(value = SqlFunctionTest.class) public class SqlFunctionTest implements Serializable {
#Id
private Long id;
#Column(name = "name")
#ColumnTransformer(
forColumn = "name",
read = "CONVERT(AES_DECRYPT(name, get_enc_key() ,get_aes_init_vector()) USING utf8)",
write = "AES_ENCRYPT(?, get_enc_key(), get_aes_init_vector())"
)
private String name;
}
I m trying to insert and select by encrypt and decrypt which I declared on my entity.
when I read it, it worked. like this.
SELECT
SQLFUNCTIO0_.ID AS ID1_13_,
SQLFUNCTIO0_.NAME AS NAME2_13_
FROM
CRYPT_TEST_TABLE SQLFUNCTIO0_
WHERE
CONVERT(AES_DECRYPT(SQLFUNCTIO0_.NAME, GET_ENC_KEY() ,GET_AES_INIT_VECTOR()) USING UTF8)='TROY.T'
but when i save an entity, it doesn't work like this.
INSERT
INTO
CRYPT_TEST_TABLE
(ID, NAME)
VALUES
(NULL, 'TROY.T')
This is the test code I did.
#Test
public void testSave(){
System.out.println("JPA TEST");
SqlFunctionTest entity = new SqlFunctionTest();
entity.setName("troy.t");
jpaCryptoService.save(entity);
}
#Test
public void testSelect(){
List<SqlFunctionTest> op = jpaCryptoService.findByName("troy.t");
System.out.println("op = " + op);
}
What's wrong with me?
