The effect of generics on spring caching using method parameter names

Known fixes for the error - org.springframework.expression.spel.SpelEvaluationException: EL1007E:(pos 0): Property or field 'id2' cannot be found on null

• Update the specific interface(s) IfDao1.java, IfDao2.java and uncomment the line that overrides the save method from the parent

• Replace the reference to method parameter name in the @CacheEvict key to #root.args[0] : also helpful if code is not compiled with debug information

Compile and run

mvn clean compile
