14 Tips for Writing Spring MVC Controllers
In this article, I'm going to share with you some of the fundamental techniques and best practices for writing a controller class with the Spring MVC framework. Typically, in Spring MVC, we write a controller class to handle requests coming from the client. Then, the controller invokes a business class to process business-related tasks, and then redirects the client to a logical view name, which is resolved by Spring’s dispatcher servlet in order to render results or output. That completes a round trip of a typical request-response cycle.

Solve your Java performance problems
The Performance Diagnostic Methodology (PDM) is a structured approach in order to find the root cause of Java performance problems. When performance issues occur, often people start panicking and start tuning the JVM without exactly knowing whether they are solving the cause of the performance issue. Therefore, a structured approach can exclude some possible causes and point you in the right direction in order to solve the issue appropriately. The approach is visualized with the next scheme.

The intent of this pattern, according to Design Patterns by Gamma et al, is to: Define an interface for creating an object, but let subclasses decide which class to instantiate. The Factory method allows a class to defer instantiation to subclasses. The Factory method is for creating objects. A superclass specifies all standard and generic behavior and then delegates the creation details to subclasses…
