I found a simpler code
``` yaml
actual-data-nodes:
ds0.$->{com.lingh.LocalShardingDatabasesAndTablesUtil.getActualDataNodes()}
```
``` JAVA
public class LocalShardingDatabasesAndTablesUtil {
public static List<String> getActualDataNodes() {
LocalDate startTime = LocalDate.now().minusDays(10);
LocalDate endTime = LocalDate.now();
return LongStream.range(0, ChronoUnit.DAYS.between(startTime,
endTime))
.mapToObj(startTime::plusDays)
.map(localDate -> "table_name_" +
localDate.format(DateTimeFormatter.ofPattern("yyyyMMdd")))
.collect(Collectors.toList());
}
}
```
``` JAVA
public class InitActualDataNodesAO {
@Resource
private ShardingSphereDataSource shardingSphereDataSource;
private final String schemaNameForTOrder = "sharding_db";
public void testSharding() {
this.reloadShardRuleActualDataNodes(shardingSphereDataSource,
schemaNameForTOrder);
}
private void reloadShardRuleActualDataNodes(ShardingSphereDataSource
dataSource, String schemaName) {
// Context manager.
org.apache.shardingsphere.mode.manager.ContextManager contextManager
= dataSource.getContextManager();
// Rule configuration.
Collection<RuleConfiguration> ruleConfigList =
dataSource.getContextManager()
.getMetaDataContexts()
.getMetaData(schemaName)
.getRuleMetaData()
.getConfigurations();
// update context
contextManager.alterRuleConfiguration(schemaName, ruleConfigList);
}
}
```
It's just need to execute `contextManager.alterRuleConfiguration()` to
reload `actual-data-nodes`
