Java Spring Hacks
A POJO is basis of the Spring framework, but also it is basis of Java and the AP CSA exam.
Hacks
AP required. Review the lambok annotations (https://projectlombok.org/features/).
- Write the POJO and show code generated by lambok. Comment this code in context of requirements for the AP exam.
PBL foundational. Establish a POJO, JPA and APIs in your own project. You can begin with Jokes.
- Make new POJO attribute. Alert, I suggest deleting /volumes/sqlite.db each time you change schema. Schema changes are not ugraded automatically.
- Make a new API endpoint.
- Test your API using Postman. You should be able to test with localhost:port.
