Introduction
This page aims to define the basic processes on how to support REST in stp, there is sample to simplifies how to create a RESTfull service from a database directly.
There are two ways to support to create RESTfull service:
* Exposing a database to RESTfull service directly * Starting from importing some POJO class into a rest project
Exposing a database to RESTfull service directly
We can create a RESTfull service by starting from a database with the following steps:
1. Firstly, we should create rest project using STP.Service Creation Wizard
add project nature "org.eclipse.jem.workbench.JavaEMFNature" which defined in WTP DALI subproject and Java Persistence Facet, once the project has the nature and JP Facet, some DALI function will be available in the subsequent steps.
2. Generate Entity classes from database
select a database to connect
select tables from the databse and click finish button
the following classes will be generated:
three entities class will be generated, these classes are annotated with JPA annotations(by the way, the used JPA implementation library is Oracle TopLink), users can modify the annotations in the generated classes through JPA detail view, it looks like:
