Missing class-level and method-level documentation. This is a new public interface that should include Javadoc explaining its purpose, usage, and the meaning of the type parameterT and method parameterkey.

Incorrect usage ofshouldContinue(). TheshouldContinue method checks if data is enabled (data.getEnabled()), but the original logic checkedselectorData.getContinued() which indicates whether to continue processing rules. These are two different concepts:enabled controls if the selector is active, whilecontinued controls whether to proceed to rule matching. The correct check should beif (!selectorData.getContinued()) instead ofif (!selectorDataDecisionMaker.shouldContinue(selectorData)).

TheshouldContinue method logic is incorrect for SelectorData. It checksdata.getEnabled(), but based on its usage in AbstractShenyuPlugin line 119, it should checkdata.getContinued() instead. Thecontinued field determines whether to continue processing rules after a selector matches, which is different from theenabled field that controls if the selector is active.

Creating a newSelectorDataDecisionMaker instance on every request is inefficient. This should be a reusable class field to avoid unnecessary object allocation.

Creating a newPluginDataDecisionMaker instance on every request is inefficient. These DecisionMaker instances are stateless and should be created once as class fields (similar to how other components are reused) to avoid unnecessary object allocation on each request. The same issue applies toSelectorDataDecisionMaker (line 107) andRuleDataDecisionMaker (line 124).
