What is Aspectran?

About Aspectran

Aspectran is a lightweight framework for building high-performance Java applications. It provides an intuitive and flexible development environment.

Aspectran Archtecture Diagram

Aspectran is a framework for developing Java applications that can be used to build simple shell applications and large enterprise web applications.

The key features of Aspectran are:

  • Support POJO (Plain Old Java Object) programming model
    Developers do not need to know the heavy and complex objects used internally by the framework. They can exchange objects with the framework using simple Java classes.
  • Support Inversion of Control (IoC)
    What’s more, the framework manages the creation and lifecycle of objects while controlling the overall flow, freeing developers to focus on their business logic.
  • Support Dependency Injection (DI)
    The framework systematically connects modules that depend on each other at runtime to ensure low coupling between modules and to increase code reusability.
  • Support Aspect-Oriented Programming (AOP)
    The framework combines additional features such as transactions, logging, security, and exception handling with code written by the developer at runtime.
  • Support building RESTful Web Services
    Aspectran is a framework designed from the ground up for REST API implementations and optimized for microservices architectures.
  • Fast development and startup time
    Aspectran’s intuitive programming model guarantees fast development time and runs faster than other frameworks.

Aspectran-based applications support the following execution environments on the JVM:

  • Consistent shell interface for command line applications
  • Built-in high performance web application server (Undertow, Jetty)
  • Daemons running as background processes
