[GitHub] [shardingsphere] lxl910128 opened a new issue #8459: test REPLICA QUERY by ShardingSphere-JDBC has a bug in version 5.0.0-alpha
lxl910128 opened a new issue #8459:
URL: https://github.com/apache/shardingsphere/issues/8459
Which version of ShardingSphere did you use?
5.0.0-alpha
Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
I want to test the feature that "replica query". I created a spring project, Use the yml file to configure it.
When I config "load-balancers" like this:
```
spring:
shardingsphere:
rules:
replica-query:
data-sources:
pr_ds:
primary-data-source-name: ds_1
replica-data-source-names: ds_0
load-balancer-name: robin
load-balancers:
robin:
type: ROUND_ROBIN
```
I got a error!
```

Through debug, I found that `ReplicaQueryAlgorithmProvidedBeanRegistry` calls the `registerBean`. In the `registerBean`, It will certainly look for it `xxx.props` like this
but in the [doc](https://shardingsphere.apache.org/document/current/en/user-manual/shardingsphere-jdbc/configuration/built-in-algorithm/load-balance/)
ROUND_ROBIN don't have any Attributes.
so I must config like this:
```
spring:
shardingsphere:
rules:
replica-query:
data-sources:
pr_ds:
primary-data-source-name: ds_1
replica-data-source-names: ds_0
load-balancer-name: robin
load-balancers:
robin:
type: ROUND_ROBIN
props:
test: test
```
I think , It’s a bug, But I don't have a good idea to fix it.
