Password encoding with Spring Data REST

Question

How should I encode automatically the subbmitted plain password field of my entity with Spring Data REST?

I\'m using BCrypt encoder and I want to automatically encod

Answer 1

You can implement a Jackson JsonDeserializer:

public class BCryptPasswordDeserializer extends JsonDeserializer {

    public String deserialize(JsonParser jsonParser, DeserializationContext deserializationContext) throws IOException {
        ObjectCodec oc = jsonParser.getCodec();
        JsonNode node = oc.readTree(jsonParser);
        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder();
        String encodedPassword = encoder.encode(node.asText());
        return encodedPassword;
    }
}

And apply it to your JPA Entity property:

// The value of the password will always have a length of 
// 60 thanks to BCrypt
@Size(min = 60, max = 60)
@Column(name="password", nullable = false, length = 60)
@JsonDeserialize(using = BCryptPasswordDeserializer.class )
private String password;
