I have the below class as my document.
@Data
@Builder
@Document(collection = "test")
public class TestData {
@Id
private String id;
private String name;
@Indexed(unique = true)
private String hash;
}
Even if I'm using Indexed with unique enabled, I'm able to insert duplicate documents into collection. But if I generate index in mongo shell then it is working.
Is there any way where I can specify unique Index through code only?
Please use following code on application.properties file on spring boot application it will work.
spring.data.mongodb.auto-index-creation: true
Thank you
This is how the compound index is used in my code
@Getter
@Setter
@Document
@CompoundIndexes({
@CompoundIndex(name = "name_author_idx", def = "{'name' : 1, 'author' : 1}", unique = true, background = true)})
public class Book implements Transformer {
@Id
private String id;
@Field(name = "name")
private String name;
@Field(name = "author")
private String author;
@Field(name = "qty")
private Integer qty;
@Field(name = "price")
private Double price;
@Field(name = "created_time")
private LocalDateTime createdTime = LocalDateTime.now();
}
If you're having a configuration component you should override the autoIndexCreation method like this:
@Configuration
public class MongoConfiguration extends AbstractMongoClientConfiguration
{
@Override
protected boolean autoIndexCreation() {
return true;
}}
