The main goal of this release is to prove that all source code has been transferred and can indeed be built into a fully compliant product.
1. Overview
Jersey is an open source framework for developing RESTful Web Services. It serves as a reference implementation of JAX-RS.
3. Web Configuration
Next, we need to set up a web project to do Servlet configuration. For this, we'll use Spring's WebApplicationInitializer:
5. Using ExceptionMapper
ExceptionMapper allows us to intercept the exceptions and return appropriate HTTP response code to the client. In the following example, HTTP response code 404 is returned if EmployeeNotFound exception is thrown:
6. Managing Resource Classes
Finally, let's wire up all service implementation classes and exception mappers against an application path:
8. Conclusion
In this article, we've introduced the Jersey framework and developed a simple API. We've used Spring for Dependency Injection features. We have also seen the use of ExceptionMapper.
