为什么 JPA 有 @Transient 注解?
Java 有 transient
关键字.为什么 JPA 有 @Transient
而不是简单地使用已经存在的 java 关键字?
Java has the transient
keyword. Why does JPA have @Transient
instead of simply using the already existing java keyword?
推荐答案
Java的transient
关键字用来表示一个字段不被序列化,而JPA的@Transient
注解用于表示一个字段不被持久化到数据库中,即它们的语义不同.
Java's transient
keyword is used to denote that a field is not to be serialized, whereas JPA's @Transient
annotation is used to indicate that a field is not to be persisted in the database, i.e. their semantics are different.
