How to access Default Idempotent Repository map from java dsl?

问题

I am newbie to Apache Camel. How can i access Camel Default Idempotent Repository map in Java DSL.

Route:

from("file://C:/folderA?noop=true")
.to("file://C:/folderB")
.end();

When i say noop=true in route, then idempotent will be true. Now i need to get Idempotent map in java dsl. Please tell me how to access this?

Thanks in advance.

If you want to access the underlying map, you should specify your own idempotentRepository bean. Using the existing MemoryIdempotentRepository should be pretty easy.

//Instantiate repository and get map
IdempotentRepository<String> repo = MemoryIdempotentRepository.memoryIdempotentRepository()
Map<String, Object> map = repo.getCache();

//Bind the repo to the Camel Context Registry using the id "repo"
//This changes depending upon how you are running Camel

//In your RouteBuilder...
from("file://C:/folderA?noop=true&idempotentRepository=#repo")
  .to("file://C:/folderB")
  .end();
