The core aggregation abstraction in Spring Data MongoDB is - as the name suggests - Aggregation. It exposes a fluent API to build up a pipeline using aggregation operations.
As of version 1.6.0.M1 the Aggregation class has a ….withOptions(…) method to be used like this:
Aggregation aggregation = newAggregation(…) // build up pipeline in here
.withOptions(newAggregationOptions().allowDiskUse(true).build());

Thanx Oliver,well what about version 1.3.2 ? and what about in version 1.5.2 ?

They don't have that feature, that's why I explicitly named 1.6 M1.

I did the same but still getting the same error. do i need to configure something else? Using mongo version 3.4

Solutions works! Previously i was doing aggregation.withOptions( options ) separately and it ignored my custom configuration;
I found spring data-mongodb to have limited support for the aggregation framework, however you can simply use the native library leveraging spring mongo template:
mongoTemplate.getCollection("myCollection").aggregate(pipeline)
See
https://github.com/mongodb/mongo-java-driver/blob/master/src/test/com/mongodb/AggregationTest.java
on how to setup the List<DBObject> pipeline and how to setup allowDiskUse to true using the AggregationOptions.

I was not being negative, I didn't know in version 1.6.0 (which is not in GA) there was a support for that nor there is anything in the documentation. I am glad more support is coming for the Aggregation framework. I do use Spring MongoDB quite a lot and in general I am very happy with it.
