Managing DAO transactions

Aspects do not only intercept the service layer but also the data transaction layer. This recipe will give us a concrete scenario when AOP is needed in most DAO transactions. Aspects implemented for the DAO layer are just limited to logging, tracing, and validating tasks due to undesirable effects when transactions become complex.

Getting started

Open ch05 and add an @Aspect that will filter null record(s) from JdbcSimpleInsert and JdbcTemplate.

How to do it...

Our first AOP implementation will be applied for managing DAO transactions. Follow the following procedure to log all the DAO transactions using aspects, advices and Pointcuts:

Before this recipe starts, be sure to have the EmployeeDao and EmployeeDaoImpl inside the packages org.packt.aop.transaction.dao and org.packt.aop.transaction.dao.impl, respectively.
To apply aspects to our DAO transactions, let us create an @Aspect inside the package org.packt.aop.transaction.core that will monitor getEmployees() and getEmployee...

Building RESTful Web Services with Spring 5

Building RESTful Web Services with Spring 5

REST is an architectural style that tackles the challenges of building scalable web services. In today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs.The depth, breadth, and ease of use of Spring makes it one of the most attractive frameworks in the Java ecosystem. Marrying the two technologies is therefore a very natural choice.This book takes you through the design of RESTful web services and leverages the Spring Framework to implement these services.
