Spring Boot MongoDB 中的 org.springframework.data.mongodb.UncategorizedMongoDbException 异常

Question

Cannot understand why this exception is happening

org.springframework.data.mongodb.UncategorizedMongoDbException: Query failed with error code 2 and error message 'Field 'locale' is invalid in: { locale: "Book" }' on server localhost:27017; nested exception is com.mongodb.MongoQueryException: Query failed with error code 2 and error message 'Field 'locale' is invalid in: { locale: "Book" }' on server localhost:27017

Book Model

public class Book {
    @Id
    @JsonProperty(value = "bookID")
    private long id;
    private String title;
    private String authors;
    private String average_rating;
    private String isbn;
    private String language_code;
    private String ratings_count;
    private String price;
}

This is happening when I am calling findAll method from MongoRepository. I have checked data in DB also and everything seems fine and there is no field with name 'locale'

Answer 1

NVM , I found the error I was using

@Document(collation= "Book")

instead of

@Document(collection = "Book")
