How to conceptualize @OneToMany mapping in JPA/Hibernate
我刚开始学习 JPA
我喜欢这样想:
1 2 3 4 5 6 7 8 9 10 11 12 13 | @Entity public class Account { // Here I read this as"One Account (The entity we are in) ToMany Transactions (The foreign entity) @OneToMany(cascade = CascadeType.ALL) private List<Transaction> transactions = new ArrayList<>(); } @Entity public class Transaction { // If we use the same process as above we get: // Many Transactions (The entity we are in) ToOne Account (The foreign entity) @ManyToOne Account account; } |
