Auditing

would you think about updating created user, created date , last updated user and last updated date automatically

=> auditing will support that.

in domain please extends extends AuditTrail<String>

then when you work with data the history will save

GET http://localhost:8080/testAuditing
{
"id": 2,
"name": "hellop"
}

how to import a service to static class

Step 1: define service normally

Step 2: define import function setMyConfig

Step 3: create a static class to import StaticContextInitializer

must use @Component and @PostConstruct to init

    @PostConstruct
    public void init() {
        CacheUtils.setMyConfig(cacheService);
    }

Now we call use CacheUtils in everywhere

Fake created_date

use @PrePersist, @PreUpdate, @PreRemove to handler action insert, update, delete

curl --location 'http://localhost:8080/testFakeCreatedDate' \
--header 'Content-Type: application/json' \
--data '{
"name": "testChange created_date"
}'

{
    "createdBy": "system",
    "creationDate": "1011-11-11",
    "lastModifiedBy": "system",
    "lastModifiedDate": "2023-05-19",
    "id": 3,
    "name": "testChange created_date"
}

the created_date is force to update to 1011-11-11
