Bug Report
For English only, other languages will not accept.
Before report a bug, make sure you have:
- Searched open and closed GitHub issues.
- Read documentation: ShardingSphere Doc.
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?
5.5.1
Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphere-JDBC
Expected behavior
expected pass the validation and run normally.
Actual behavior
Error Info:
Algorithm 'Object.'INLINE' initialization failed, reason is: `sensitivityShardingAlgorithm` sharding algorithm configuration of `logic_base_visual_release` does not match the actual data nodes.
Reason analyze (If you can)
In org.apache.shardingsphere.sharding.rule.ShardingTable
class createDataSourceDataNode
method.
private static final Pattern DATA_NODE_SUFFIX_PATTERN = Pattern.compile("\\d+$");
...
String prefix = DATA_NODE_SUFFIX_PATTERN.matcher(actualDataNodes.iterator().next().getDataSourceName()).replaceAll("");
prefix val is ds_normal
But in org.apache.shardingsphere.sharding.rule.checker.ShardingRuleChecker
class validateInlineShardingAlgorithm
method.
check expression is null == result || result.startsWith(dataNodeInfo.getPrefix())
result val is ds_sensitive
, not match prefix result, then throw exception.
Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
The following configuration defines two data sources, named ds_normal and ds_sensitive. The sharding rules are defined using an enumerated value in a Groovy line expression. It works fine in version 5.3.2, but an error occurs when running in version 5.5.1.

ds_normal:
...
ds_sensitive:
...

- !SHARDING

logic_base_visual_release:
actualDataNodes: "ds_$->{['normal', 'sensitive']}.base_visual_release"
