spring-boot-data-couchbase

The different exceptions while using spring-boot-data-couchbase and how I swam through

(1) An ID property is needed, but not found/could not be generated on this entity.

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [void]: Factory method ‘insertData’ threw exception; nested exception is org.springframework.data.mapping.MappingException: An ID property is needed, but not found/could not be generated on this entity.

I had javax.validation annotation @NotNull for id field

public class Building {

    @NotNull
    @Id
    @GeneratedValue
    private String id;

Removed the @NotNull annotation to resolve the issue.

(2) The Document ID must not be null or empty.

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [void]: Factory method ‘insertData’ threw exception; nested exception is java.lang.IllegalArgumentException: The Document ID must not be null or empty.

Used the following strategy for ID Generation to resolve the issue.

public class Building {

    @Id
    @GeneratedValue(strategy = UNIQUE)
    private String id;

import org.springframework.data.annotation.Id;
import org.springframework.data.couchbase.core.mapping.Document;
import org.springframework.data.couchbase.core.mapping.id.GeneratedValue;
import static org.springframework.data.couchbase.core.mapping.id.GenerationStrategy.UNIQUE;

Hope this helps
