In this chapter, we will go into the details of building synchronous microservices with Java EE 8. We will learn how to implement server-side REST APIs using basic JAX-RS annotations, implement sub-resource locators for nested REST APIs, and use HTTP status codes and exception mappers for exception handling. You will also learn how to implement the client side using JAX-RS client APIs, and finally, we will have a look at different test strategies for Java EE web services.
We'll cover the following sections in this chapter:
- Implementing basic REST APIs with JAX-RS
- Using sub-resources
- Error handling in JAX-RS
- Implementing web service clients with Java EE 8
- Testing Java EE 8 web services
By the end of this chapter, we'll have implemented a small library microservice that offers a REST API for books, authors, and loans. We...
