问题 lately I've been doing some projekt with Spring Data and Rest with HATEOAS. My question is, is it normal, that in entity links secion, I have 2 same links?

问题 Is there a SpringData Mongo equivalent of the JPA @Column annotation? Basically, I've got a POJO with a property that I want to store in Mongo with a different name. So, the following object: public class Pojo{ @Property("bar") private String foo = "Hello World"; } would be persisted as: { "_class":"com.example.Pojo", "bar" : "Hello World" } Note: I don't want to use the MappingMongoConverter to explicitly do it 回答1: The Spring Data reference documentation lists @Field as the annotation to
