I will provide the configuration again
`CREATE TABLE tf_b_bank_info(idbigint(20) NOT NULL AUTO_INCREMENT,bankno
varchar(25) COLLATE utf8_bin DEFAULT NULL, PRIMARY KEY (id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8 COLLATE=utf8_bin
COMMENT='';
CREATE TABLE tf_b_bank_user (
id bigint(20) NOT NULL AUTO_INCREMENT,
bank_id bigint(20) DEFAULT NULL COMMENT '银行类型:tf_b_bank_info的id',
bankno varchar(255) COLLATE utf8_bin DEFAULT NULL COMMENT '银行卡号',
DELETE_USER_NAME varchar(255) COLLATE utf8_bin DEFAULT NULL COMMENT '',
PRIMARY KEY (id)
) ENGINE=InnoDB AUTO_INCREMENT=178026 DEFAULT CHARSET=utf8 COLLATE=utf8_bin
COMMENT='';``
execute sql statement：
`SELECT t.ID, t.BANKNO, tt.bankno banknono FROM tf_b_bank_user t JOIN
tf_b_bank_info tt ON tt.id = t.bank_id`
Execute the final result:
When two tables have bankno fields at the same time, both table bankno
fields will be converted to DELETE_USER_NAME fields
java api configuration :
`@Configuration
@AutoConfigureBefore(DruidDataSourceAutoConfigure.class)
public class ShardingConfigurer {
@Bean
public DataSource masterDataSource() {
return DruidDataSourceBuilder.create().build();
}
@Bean
@DependsOn({"masterDataSource"})
@Primary
public DataSource dataSource(DataSource masterDataSource) throws Exception {
Map<String,DataSource> dataSourceMap = new HashMap<>();
dataSourceMap.put("ds_0", masterDataSource);
Properties properties = new Properties();
properties.setProperty(SQL_SHOW.getKey(), "true");
return ShardingSphereDataSourceFactory.createDataSource(
dataSourceMap,
Arrays.asList(
createEncryptRuleConfiguration())
, properties);
}
public EncryptRuleConfiguration createEncryptRuleConfiguration() {
Map<String, ShardingSphereAlgorithmConfiguration>
encryptAlgorithmConfigs = new LinkedHashMap<>();
Properties encryptProperties = new Properties();
encryptProperties.setProperty("aes-key-value", "123456");
encryptAlgorithmConfigs.put("aes", new
ShardingSphereAlgorithmConfiguration("AES", encryptProperties));
Collection<EncryptTableRuleConfiguration> tables = new LinkedList<>();
Collection<EncryptColumnRuleConfiguration> columns = new LinkedList<>();
EncryptColumnRuleConfiguration columnRuleConfiguration = new
EncryptColumnRuleConfiguration("BANKNO","bankno_cipher",null,"bankno","aes");
columns.add(columnRuleConfiguration);
EncryptTableRuleConfiguration result = new
EncryptTableRuleConfiguration("tf_b_bank_user", columns);;
EncryptRuleConfiguration encryptRuleConfiguration = new
EncryptRuleConfiguration(tables,encryptAlgorithmConfigs,false);
return encryptRuleConfiguration;
}`
