SpringBoot整合ShardingSphere5.x实现数据加解密功能

环境:Springboot2.6.14 + ShardingSphere5.3.0


准备环境

  • 添加依赖


  org.apache.shardingsphere
  shardingsphere-jdbc-core
  ${shardingsphere.version}


  com.baomidou
  mybatis-plus-boot-starter
  ${mybatis-plus.version}


  com.baomidou
  mybatis-plus-generator
  ${mybatis-plus.version}
  • 数据表users

  1. pwd:明文字段

  2. pwd_clipher:密文字段

  3. assisted_query_pwd:查询辅助列

  • 配置文件

application.yml配置文件(Springboot)

spring:
  datasource:
    driverClassName: org.apache.shardingsphere.driver.ShardingSphereDriver    
    url: jdbc:shardingsphere:classpath:config.yaml
    name: EncryptHikariCP
---
mybatis-plus:
  configuration:
    mapUnderscoreToCamelCase: true
  mapperLocations: classpath*:/mapper/**/*.xml
  typeAliasesPackage: com.pack

config.yaml配置文件(ShardingSphere)

#数据源配置
dataSources:
  ds1:
    dataSourceClassName: com.zaxxer.hikari.HikariDataSource
    driverClassName: com.mysql.cj.jdbc.Driver
    jdbcUrl: jdbc:mysql://localhost:3306/testjpa?serverTimezone=GMT%2B8&useSSL=false
    username: root
    password: 123123
    minimumIdle: 10
    maximumPoolSize: 200
    autoCommit: true
    idleTimeout: 30000
    poolName: MasterHikariCP
    maxLifetime: 1800000
    connectionTimeout: 30000
    connectionTestQuery: SELECT 1
#规则配置
rules:
- !ENCRYPT #加解密相关配置
  tables:
    users:
      columns:
        pwd:  #逻辑列(如果是老系统一般都会吧这个逻辑列和实际物理列名一致)
          plainColumn: pwd  #实际物理列名
          cipherColumn: pwd_cipher #加密后的列名
          encryptorName: pwd_encryptor  #加密列使用的加密算法(对应下面的配置)
          #assistedQueryColumn: assisted_query_pwd
          #assistedQueryEncryptorName: assisted_encryptor
      queryWithCipherColumn: true
  encryptors:
    pwd_encryptor:
      type: SM4
      props:
        sm4-key: aaaabbbbccccdddd1111222233334444
        sm4-mode: ECB
        sm4-iv: aabbccddeeffgghh
        sm4-padding: PKCS7Padding
    assisted_encryptor:
      type: SM3
      props:
        sm3-salt: aaaabbbb
#执行时打印SQL
props:
  sql-show: true    

有了上面配置后,接下来就可以进行相应的CRUD操作了。

CRUD操作

实体对象


@TableName("users")
public class Users {
  
  @TableId(type = IdType.ASSIGN_ID)
  private Long id;
  private String name;
  @TableField("id_no")
  private String idNo ;
  private Integer age;
  private String email;
  private String pwd ;
}

Mapper类


public interface UsersMapper extends BaseMapper {
  
}

测试类


@SpringBootTest
public class UserMapperTest {
  
  @Resource
  private UsersMapper usersMapper ;
  @Resource
  private IUsersService us ;
  @Resource
  private List dataSources ;
  
  @Test
  public void testUserList() {
    QueryWrapper queryWrapper = new QueryWrapper<>() ;
    queryWrapper.eq("pwd", "999999") ;
    System.out.println(this.usersMapper.selectList(queryWrapper)) ;
  }

  @Test
  public void testSave() {
    Users user = new Users() ;
    user.setAge(99) ;
    user.setEmail("[email protected]") ;
    user.setIdNo("999999") ;
    user.setName("久久") ;
    user.setPwd("999999") ;
    
    this.usersMapper.insert(user) ;
  }

}

测试结果

数据源及查询辅助列

  • 数据源配置

在config.yaml文件中我们配置了连接池信息,但是实际没有生效。如上配置的最小连接数是10,最大是200,但是实际打印都成了默认值都是10。最后修改连接池配置方式如下:

spring:
  datasource:
    driverClassName: org.apache.shardingsphere.driver.ShardingSphereDriver    
    url: jdbc:shardingsphere:classpath:config.yaml
    name: EncryptHikariCP
    hikari:
      minimumIdle: 10
      maximumPoolSize: 200
      autoCommit: true
      idleTimeout: 30000
      poolName: BaseHikariCP
      maxLifetime: 1800000
      connectionTimeout: 30000
      connectionTestQuery: SELECT 1

如上配置后连接池才正常。

  • 辅助查询列

辅助查询列会根据你的配置是否使用辅助列,当没有配置辅助查询列时,执行SQL如下:

使用的是加密列进行查询了

当配置了辅助查询列后:

使用的是辅助列查询。

完毕!!!
