Class RepeatOperationsInterceptor
java.lang.Object
org.springframework.batch.repeat.interceptor.RepeatOperationsInterceptor
- All Implemented Interfaces:
- org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor
public class RepeatOperationsInterceptor
- extends Object
- implements org.aopalliance.intercept.MethodInterceptor
A MethodInterceptor
that can be used to automatically repeat calls to a method on a service. The injected
RepeatOperations
is used to control the completion of the loop. By default it will repeat until the target
method returns null. Be careful when injecting a bespoke RepeatOperations
that the loop will actually
terminate, because the default policy for a vanilla RepeatTemplate
will never complete if the return type of
the target method is void (the value returned is always not-null, representing the Void.TYPE
).
