Spring Boot - Entity Relationship

This simple project shows an implementation of a one-to-one relationship between two entity classes in Spring Boot.

Demonstration: Sample REST Requests

• Request 1.

curl -X POST -H "Content-Type:application/json" -d '{"name":"My Library"}' http://localhost:8081/libraries

which returns

{"id":1,"name":"My Library"}

• Request 2.

curl -X POST -H "Content-Type:application/json" -d '{"location":"Main Street nr 5"}' http://localhost:8081/addresses

which returns

{"id":2,"location":"Main Street nr 5","library":null}

• Request 3.

curl -i -X PUT http://localhost:8081/libraries/1/address/2

which returns

{"id":1,"name":"My Library"}

• Request 4.

curl -X GET http://localhost:8081/addresses/2

which returns

{"id":2,"location":"Main Street nr 5","library":{"id":1,"name":"My Library"}}

Note that the value of "library" has been updated from null to {"id":1,"name":"My Library"}.

Windows CMD

In Windows, you need to escape additional single or double quotes with a backslash; for example:

curl -X POST -H "Content-Type:application/json" -d "{\"name\":\"My Library\"}" http://localhost:8081/libraries
