[GitHub] [shardingsphere] piggytough opened a new issue #7905: shardingsphere-jdbc standard alg. initialization problem
piggytough opened a new issue #7905:
URL: https://github.com/apache/shardingsphere/issues/7905
### Which version of ShardingSphere did you use?
5.0.0-RC1-SNAPSHOT
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### problem
standard sharding algorithm configuration not loaded
configuration below:
```
spring:
shardingsphere:
dataSources:
...
rules:
sharding:
tables:
quantityaggregationdata:
logicTable: quantityaggregationdata
actualDataNodes: shardingdata.quantityaggregationdata_0_$->{0..7}
tableStrategy:
standard:
shardingColumn: logtime
shardingAlgorithmName: range-sharding
tx: com.example.demosharding.strategy.ShardingAlgorithm
keyGenerateStrategy:
column: id
keyGeneratorName: snowflake
shardingAlgorithms:
range-sharding:
type: BOUNDARY_RANGE
props:
sharding-ranges: 0, 10, 20, 30, 40, 50, 60, 70
```
cause I cannot find some useful configuration example except for INLINE sharding, i'm not sure my config is properly set.
In my opinion, maybe the initation function's not called before doSharding. like this.
## Maybe complex sharding's got the same problem as well.
thank you!

Yeah I tried. like this:
1) the initiazation never triggered.
2) after manually init and got partitionRange, another error occured. Integer cast to Long problem.

Have you ever tried inserting data? The result is your expect?

sorry for replying late.
I made a pull yesterday, it's almost latest. I made the breakpoint by it's not loaded. howhowever the bean BoundaryBasedRangeShardingAlgorithm is loaded, I can't find any clue.
btw. my configuration's like below, I can't find anything wrong with that but the init is never loaded.

For Q1, can you make a breakpoint here, ensure the algorithm is loaded.
By the way your code is lastest?

thanks for your reply.
I've read the document, a detailed configuration example. Yet my main question still remains.
I mean, **the initialization of algorithm is not properly triggered while applicaition''s started**, few clue's found. Couldyou check out this for me? thank you.
BTW, I suggest buildin complex algorithm like range + hash etc.

Did you have a custom BeanPostProcessor? It seem some class skipped auto proxying.

Oh sorry, My FAULT. After reCreating a demo project, it's ok to init. maybe some class's made the skip, I'll find that.
thank you for your patience. problem closed.

nope, it's only a simple demo. few classes were created except for ordinary controller/repository and druid connection. I can't see anything special

Meanwhile, what''s the difference between autotable and table?
