Error: The method where(String) is undefined while using spring boot mongodb

Question

I have added the mongodb dependencies in my spring boot app however I am getting undefined error on "where" method:

ChangeStreamRequest<Person> request = ChangeStreamRequest.builder()
    .collection("person")
    .filter(newAggregation(Person.class, match(where("operationType").is("insert"))))
    .publishTo(pListener)
    .build();

POM configuration:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb-reactive</artifactId>
</dependency>

Please advise me on this

The reason for "undefined" is "there is no method where defined in your class".

You have to import where method from Criteria.

You can use Criteria.where("operationType").is("insert") by adding the below import statement.

import org.springframework.data.mongodb.core.query.Criteria;

Alternatively you can add a static import as below:

import static org.springframework.data.mongodb.core.query.Criteria.where;

Now, you can directly use :

where("operationType").is("insert")

Thank you, it is difficult to find the references of static methods — Vishwa Dany, Nov 11 '18 at 11:50
