A Java annotation processor that generates a full REST API, handling entity persistence using Spring, Javapoet, JDBC, etc

Code-Xpress-annotation-processor

A Java annotation processor for entity persistence using Spring, using the idea to generate Java code in the compilation time, with CX annotation you will be enabled to create a REST API just annotation simple Java classes, create full APIs without adding new heavy frameworks and using a very straightforward approach

With a class like this, using the CX annotations, the annotation processor will generate a full CRUD RESTful service that be can accesed through <host_url>:<server.port>/CX/{custom-path-for-cx-entity} with GET, POST, PUT, DELETE HTTP requests!

Features:

• Repository, Service, Controller layers auto-generated
• Auto table creation
• Using REST standard for API's
• JSON response for auto generated controllers
• Configurable database connection using JDBC
• Custom API base path
• Database table creation by CX entities
• Full CRUD actions by CX entity definition
