## Bug Report
**For English only**, other languages will not accept.
Before report a bug, make sure you have:
- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more details.
If no response anymore and we cannot reproduce it on current information, we will **close it**.
Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
5.1.2
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
### Expected behavior
work correctly
### Actual behavior
in the spi-based-sharding-spring-boot-jpa-example project:
the error log:
### Reason analyze (If you can)
the custom algorithm is not implemented and configured correctly
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
### Example codes for reproduce this issue (such as a github link).

> I also have this problem I found that all the init () methods of standardshardingalgorithm were not executed. As a result, every standardshardingalgorithm is not fully initialized. This problem is particularly obvious when you just try hashmodshardingalgorithm. The shardingcount attribute inside is a 0. It uses an int type. If you hit a breakpoint, you won't enter
They are maybe different problems. One is for loading not existed SPI, your issue is codes can find SPI, but not call init method.

@doveylovey For your issue, I think that the `T_ORDER_SPI_BASED` is your own sharding algorithm type.
Please try to understand the example, and run the original example to make sure the example is fine.

I also have this problem,What is your version,Is it an official example of use
I found that all the init () methods of standardshardingalgorithm were not executed.
