Spring 引导：使用注释执行加密/解密：MongoDB

Question

I have a requirement where I have to encrypt a field before saving in the database and decrypt it while retrieving it. The fields that should be encrypted should be custom annotated.

I am using spring-boot with MongoDB for this.

Example:

Class Person {

Long ID;

String userName;

String password;

@EncryptThisField
String firstName;

@EncryptThisField
String lastName;

... SETTER and GETTERS

}

Based on annotation my setter should set encrypted value(and save to database) and getter should return decrypted value(and retrieve from database).

Any pointers or suggestions?

Answer 1

you should create two functional-interface. One to encrypt and other decrypt. use the annotation on the setter and getter methods instead of on the field.
