类 ValidationFilter

java.lang.Object

org.apache.dubbo.validation.filter.ValidationFilter

所有已实现的接口:

Filter

@Activate(group={"consumer","provider"},
          value="validation",
          order=10000)
public class ValidationFilter
extends Object
implements Filter

ValidationFilter invoke the validation by finding the right Validator instance based on the configured validation attribute value of invoker url before the actual method invocation.

     e.g. <dubbo:method name="save" validation="jvalidation" />
     In the above configuration a validation has been configured of type jvalidation. On invocation of method save
     dubbo will invoke JValidator
 

To add a new type of validation

     e.g. <dubbo:method name="save" validation="special" />
     where "special" is representing a validator for special character.
 

developer needs to do
1)Implement a SpecialValidation.java class (package name xxx.yyy.zzz) either by implementing Validation or extending AbstractValidation
2)Implement a SpecialValidator.java class (package name xxx.yyy.zzz)
3)Add an entry special=xxx.yyy.zzz.SpecialValidation under META-INF folders org.apache.dubbo.validation.Validation file.
