Detailed Description
The present application will be further described in detail below with reference to specific embodiments and with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present application more apparent.
It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present application should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present application belongs. The terms "first," "second," and the like, as used in embodiments of the present application, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a method for encrypting and decrypting a database field according to an embodiment of the present application includes the following steps:
step S101, obtaining parameter entering information of a target object, wherein the parameter entering information comprises parameter list data.
In some embodiments, the target objects include insert, update, delete, select, and return objects.
In some embodiments, an Interceptor is defined by an Interceptor interface to intercept the target object.
By using the plug-in mechanism provided by MyBatis, the user can conveniently insert own logic in the SQL executing process.
The plug in method of the plug in needs to be focused on, the method returns the proxy object to be proxied, and meanwhile, the current intersator instance is set in an intersectional set of the Configuration object, so that the interception is needed to be carried out on target objects such as insert/update/delete in MyBatis, and the acquired target object parameter entering information is needed.
Step S102, judging whether the parameter list data contains a character string with a custom annotation.
In some embodiments, the parameter list data and the type corresponding to each parameter are obtained, the character string name and the type of the parameter object are obtained through a reflection mechanism, and the marked character string is determined.
Specifically, the present embodiment may use a Java reflection mechanism to obtain a corresponding Field object according to a class and a Field name, and determine whether the character string (or Field) is annotated by @ encryptefield.
And step 103, responding to the character string attribute containing the custom annotation in the parameter list data, calling an encryption algorithm to encrypt the character string, executing the target object operation, and returning an execution result.
Step S104, judging whether the execution result is of a collection type.
Step 105, in response to the execution result being a set, traversing the set, performing annotation scanning on the entity attribute of each set element to determine whether the entity attribute needs decryption, in response to the entity attribute needing decryption, judging whether the entity attribute is a character string, in response to the entity attribute being a character string, invoking a decryption algorithm to decrypt the entity attribute, and returning to the plaintext.
Specifically, since the query result may include multiple lines of data, the returned result may be a set, so that to implement unified processing of different service scenarios, we need to perform different processing on different types of returned values, and if the query result is an object list, we need to process each object in the list one by one.
The encryption and decryption algorithm adopted in this embodiment is a conventional encryption and decryption algorithm in the field, such as DES, 3DES, AES, etc., and will not be described in detail here.
Before implementing the encryption and decryption method, the embodiment needs to create a Spring Boot starter item named as springboot-mybatis-crypt-starter, the item should contain code implementation of an encryption and decryption module, and provide corresponding infrastructures such as annotation and interface, so that a service system can access quickly, and in order to enable the service system to implement their encryption and decryption method by itself, we need to define a custom annotation, such as @ encryptefield, which means that a certain field needs encryption processing. Meanwhile, an Encryptor interface, such as Encryptor, needs to be defined, and specific encryption logic can be realized in a service system according to specific scenes, so that the expandability and flexibility of an encryption algorithm are ensured.
The application aims to increase encryption and decryption actions in the front and back of an operation database by using a Mybat interceptor, and automatically encrypts and decrypts the data stored in the database in a form of annotating a designated field, so that the data stored in the database is ensured to be ciphertext, and the data result is inquired to be plaintext.
