java - Spring Boot Validation Set Parameter Name Provider -

-

i had validator bean used reflectionparameternameprovider return correct reflected variables names e.g. methodname.myvarname oppose methodname.arg0

@bean public validator validator() {     final validatorfactory validatorfactory = validation.bydefaultprovider()             .configure()             .parameternameprovider(new reflectionparameternameprovider())             .buildvalidatorfactory();     return validatorfactory.getvalidator();

this worked correctly not autowire beans in custom validator. enable beans autowire in constraintvalidator must use.

@bean public validator validator() {     return new localvalidatorfactorybean(); }

however cannot use reflectionparameternameprovider.

question

how use localvalidatorfactorybean reflectionparameternameprovider?

spring's localvalidatorfactorybean should include defaultparameternamediscoverer in turn should rely on standardreflectionparameternamediscoverer. not working you? on java 8? standardreflectionparameternamediscoverer should pretty similar reflectionparameternameprovider
