Dozer with Kotlin

This is a simple demo project to show the usage of Dozer in a Spring Boot Kotlin project. Dozer can be used map and copy objects recursively. This can provide much benefit in a layered architecture. For example when a domain object must be mapped to DTOs or database entities.

Run it

./gradlew bootRun

Then make some calls against the REST APIs:

POST to http://localhost:8080/users
GET  to http://localhost:8080/users
GET  to http://localhost:8080/users/<userId>

Examples

Note that the payload of the following examples is slightly different in each case. Every request represents another view on the user. All objects contain a different set of fields. This is a typical use-case where Dozer is very handy.

Create a new user:

POST to localhost:8080/users:

{
    "firstName": "Jon",
    "lastName": "Doe",
    "nickName": "jonny3000",
    "password": "123456",
    "addresses": [
        { "street": "Teststreet 42", "city": "Testcity" }
    ]
}

Request a list of all users:

GET to localhost:8080/users

[
    {
        "nickName": "jonny3000"
    }
]

Request a single user by its internal unique ID:

GET to localhost:8080/users/<see log for user ID>

{
    "firstName": "Jon",
    "lastName": "Doe",
    "nickName": "jonny3000",
    "addresses": [
        { "street": "Teststreet 42", "city": "Testcity" }
    ]
}
