I have the same problem.
I change ctual-data-nodes just like @jianzh5's code. When I insert data, the
key generator not works.
It should be:
{
"id": 818611524267409408, <------ without change sharding rule
"orderId": 1,
"orderMessage": "1",
"createTime": "2022-01-01 02:10:10"
},
but it was:
{
"id": 5, <------- key generator not work
"orderId": 1,
"orderMessage": "1",
"createTime": "2022-01-01 02:10:10"
}
My code:
`
@Override
public void run(ApplicationArguments args) throws Exception {
logger.debug("in " + this.getClass().getName() + "::run()");
//ContextManager contextManager =
this.getContextManager(this.shardingSphereDataSource);

LinkedList<>();
Collection<RuleConfiguration> oldRuleConfigurations =
contextManager.getMetaDataContexts().getMetaData().getDatabases()
.get("logic_db").getRuleMetaData().getConfigurations();
ShardingSphereDatabase database =
contextManager.getMetaDataContexts().getMetaData().getDatabases().get("logic_db");
for (RuleConfiguration config: oldRuleConfigurations) {
if (config instanceof ShardingRuleConfiguration) {
ShardingRuleConfiguration oldShardingRuleConfig
= (ShardingRuleConfiguration)config;
ShardingRuleConfiguration newShardingRuleConfig
= new ShardingRuleConfiguration();
// 根据分片算法名称获取分片算法配置

oldAlgorithmConfigs = oldShardingRuleConfig.getShardingAlgorithms();

}
});
