我想在MongoDB中插入一个类似于下面的bean,我使用了Springboot2.0.4.release,我想a字段有一个默认值,比如100.00,怎么做?
public class Bean{ String uid; double a; }
您必须对bean进行注释,最好在集合中包含id。
import org.springframework.data.annotation.Id; import org.springframework.data.mongodb.core.mapping.Document; @Document(collection = "your_collection_name") public class Bean { @Id private String id; private String uid; private double a = 100.00; //getter and setter methods }
