Thank you for your answer, it is indeed that my configuration file is wrong.
Change
```yaml
spring:
shardingsphere:
rules:
sharding:
tables:
tb_result3_sharding_sphere:
actual-data-nodes: ds0.tb_result3_sharding_sphere_$->{0..366}
```
to
```yaml
spring:
shardingsphere:
rules:
sharding:
tables:
tb_result3_sharding_sphere:
actual-data-nodes: ds0.tb_result3_sharding_sphere_$->{1..366}
```
The main reason is that when I created the table according to the rules of
the custom sharding algorithm, tb_result3_sharding_sphere_0 was not created.
The problem has been resolved, I will close this issue.
