mybatis-encrypt-spring-boot-parent

A spring-boot starter to encrypt and decrypt some column of database

Maven Central

Tips: For running test application I recommend you to set the correct path that you can get a cleanning project directory.

  • Set value of spring.datasource.url
spring:
  datasource:
    embedded-database-connection: h2
    driver-class-name: org.h2.Driver
    #url: jdbc:h2:mem:h2;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    url: jdbc:h2:/Users/weasley/Development/IdeaProjects/mybatis-encrypt-spring-boot-parent/mybatis-encrypt-spring-boot-tests/h2;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
    username: ""
    password: ""
  • Set value for alphahub.dtt.all-in-one-table.filepath and alphahub.dtt.code-generator.module-path
alphahub:
  dtt:
    show-sql: on
    all-in-one-table:
      enable: true
      filename: all_in_one.sql
      filepath: /Users/weasley/Downloads
    code-generator:
      is-enable: on
      include-controller: on
      include-interface: on
      override-exists: off
      remove-prefix: dtt
      base-classes:
        - com.example.demain.DttMember
      module-name: example
      module-package: com.example
      module-path: /Users/weasley/Development/IdeaProjects/mybatis-encrypt-spring-boot-parent/mybatis-encrypt-spring-boot-tests

Quick start

1 Add dependences for your project pom.xml

<!-- mybatis-encrypt -->
<dependency>
    <groupId>io.github.weasley-j</groupId>
    <artifactId>mybatis-encrypt-spring-boot-starter</artifactId>
    <version>1.0.3</version>
</dependency>

2 Configure your configuration yaml file

MyBatis encryption configuration，2 algorithms embeded. you can choose one of them. Or you can implement you own algorithm.

2.1 Base64 algorithm

# mybatis encryption configuration
mybatis:
  encrypt:
    enable: on
    encrypt-type: base64

2.2 AES algorithm

Replace your own key and keyIv

# mybatis encryption configuration
mybatis:
  encrypt:
    enable: on
    encrypt-type: aes
    aes:
      key: Jidkdp1mWL1tRyK=
      key-iv: Poikdp1mWL1jijK=

2.3 DIY algorithm

As you choose encrypt-type = diy，you must implement io.github.weasleyj.mybatis.encrypt.core.EncryptStrategy to define your own algorithms for encryption and decryption some column of database,

# mybatis encryption configuration
mybatis:
  encrypt:
    enable: on
    encrypt-type: diy
    diy:
      encrypt-strategy: com.somepackage.YourEncryptStrategyImpl

3 Use @EnableMybatisEncryption annotation to annotate a Bean of your application that Spring AOC can find it

  • Annotate on Java configuration class
import io.github.weasleyj.mybatis.encrypt.annotation.EnableMybatisEncryption;
import org.springframework.context.annotation.Configuration;

/**
 * Mybatis Encrypt Configuration class
 *
 * @author weasley
 * @version 1.0.0
 */
@Configuration
@EnableMybatisEncryption
public class MybatisEncryptConfig {

}
  • Annotate on your SpringBoot aplciation Main class
import io.github.weasleyj.mybatis.encrypt.annotation.EnableMybatisEncryption;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * Some application Main class
 */
@SpringBootApplication
@EnableMybatisEncryption
public class SomeApplication {
    public static void main(String[] args) {
        SomeApplication.run(SomeApplication.class, args);
    }
}

3 Wirte a Java bean that MyBatis can map with table column

  • Use @Encryption annotate on the field property which you need encryption and decryption，Here is an example to decrypt and encrypt nickname:

    private String openId;
    /**

    @Encryption
    private String nickname;
    /**

     */
    private Boolean isEnable;
    /**

     *
     * @precision 10
     * @scale 4
     * @defaultValue 0.01
     */
    private BigDecimal balance;
    /**
     * 出生日期，格式：yyyy-MM-dd HH:mm:ss
     */
    private LocalDateTime birthday;
    /**
     * 用户状态；0 正常(默认)，1 已冻结，2 账号已封，3 账号异常
     *
     * @defaultValue 3
     */
    private Integer status;
    /**
     * 账户注销状态；0 未注销（默认），1 已销户
     *
     * @defaultValue 1
     * @dbDataType SMALLINT
     */
    private Integer deleted;
    /**
     * 注册时间，格式: yyyy-MM-dd
     */
    private LocalDate registrarDate;
    /**
     * 会员加速开始时间, 格式：HH:mm:ss
     */
    private LocalTime accelerateBeginTime;
    /**
     * 会员加速结束时间, 格式：HH:mm:ss
     */
    private LocalTime accelerateEndTime;
    /**
     * 修改时间
     */
    private LocalDateTime updateTime;
}
