java - Spring Boot - @Convert不调用convertToDatabaseColumn方法

Question

我想使用@Convert来加密我的数据库数据，以下是我的代码部分。我遇到的问题是当我设置 @Converter(autoApply = true) 时它工作正常并且所有字符串属性都完美加密。但是当我将其设置为 False 时，我想要加密的属性不会加密，并且永远不会调用 ConvertToDatabaseColumn。我错过了什么？

实体类

@Entity
@Table(name="tbl_offer_log")
public class DbLogTable {

   @Column(name = "id", length=100)
   private int id;

   //Column I want to encrypt 
   @Column(name="msisdn",length=9)
   @Convert(converter = EncryptDecrypt.class)
   private String msisdn;
}

属性转换器

@Converter
public class EncryptDecrypt implements AttributeConverter<String, String> {

    private static SecretKeySpec secretKey;
    private static byte[] key;

    @Override
    public String convertToDatabaseColumn(String strToEncrypt) {
        try
        {
            String secret="secret";
            setKey("secret");
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
            cipher.init(Cipher.ENCRYPT_MODE, secretKey);
            return Base64.getEncoder().encodeToString(cipher.doFinal(strToEncrypt.getBytes("UTF-8")));
        } 
        catch (Exception e) 
        {
        }
        return null;
    }
}

您可以像这样在实体类级别尝试 @Converts 并看看它是否适合您吗？

@Entity 
@Converts({
            @Convert(attributeName="msisdn", 
                     converter=EncryptDecrypt.class)})
@Table(name="tbl_offer_log")
public class DbLogTable {

   @Column(name = "id", length=100)
   private int id;

   //Column I want to encrypt 
   @Column(name="msisdn",length=9)
   private String msisdn;
}
