Client Oriented Dynamic Search Query Supporting Multiple Tables in Spring

  • Java 8 is installed.
  • Any Java IDE (preferably STS or IntelliJ IDEA).
  • Basic understanding of Java and Spring-based web development along with Spring Data JPA.

I used Spring Initializer to add all the dependencies and create a blank working project with all my configurations. I used Maven as project build type and Java 8 as language, though this part is up to your choice as long as it is supported by spring. Below are my required dependencies which can easily be added from spring initializer.

Servlet 3.0 Async Support in Spring and Performance Misconceptions

It is possible to improve the performance of application servers using Servlet 3.0 async, but is it necessary?

Before We Start

Spring makes it easy to write Java applications. With Spring Boot, it became even easier. Spring Boot allows us to quickly create Spring applications: build and run a Java application server with embedded Tomcat and your own controller in less than 5 minutes. Well, I admit I used Spring Initializer for that:
