sping-boot-starter-data-mongob似乎不包含使用@PrePersist@PreUpdate的持久性API

Question

使用sping-boot-starter-data-mongob时，包含和使用JPA实体生命周期事件的正确方法是什么？

我的pom。xml依赖项

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-mongodb</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-rest</artifactId>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

我的类路径没有看到以下任何JPA注释：

@PrePersist
@PostPersist
@PreRemove
@PostRemove
@PreUpdate
@PostUpdate
@PostLoad

Mongo有自己的事件记录在@#Entity回调中。

例子：

class DefaultingEntityCallback implements BeforeSaveCallback<Person>, Ordered {      

    @Override
    public Object onBeforeSave(Person entity, String collection) {                   

        if(collection == "user") {
            return // ...
        }

        return // ...
    }

    @Override
    public int getOrder() {
        return 100;                                                                  
    }
}

提供以下功能接口：

> < Li > < p > org . spring framework . data . MongoDB . core . mapping . event . afterconvertcallback

org.springframework.data.mongodb.core.mapping.event.AfterSave回调

org . spring framework . data . MongoDB . core . mapping . event . beforecovertcallback

org.springframework.data.mongodb.core.mapping.event.之前保存回调

org . spring framework . data . MongoDB . core . mapping . event . reactiveafterconvertcallback

org.springframework.data.mongodb.core.mapping.event.ReactiveAfterSaveCallback

org.springframework.data.mongodb.core.mapping.event.ReactiveBeforeConvertCallback

org.springframework.data.mongodb.core.mapping.event.ReactiveBeforeSaveCallback
