Remote access framework

By -
Spring's Remote Access framework is an abstraction for working with various RPC-based technologies available on the Java platform both for client connectivity and marshalling objects on servers. The most important feature offered by this framework is to ease configuration and usage of these technologies as much as possible by combining inversion of control and AOP.The framework also provides fault-recovery (automatic reconnection after connection failure) and some optimizations for client-side use of EJB remote stateless session beans.
Spring provides support for these protocols and products out of the box
  • HTTP-based protocols
    • Hessian: binary serialization protocol, open-sourced and maintained by CORBA-based protocols
    • RMI (1): method invocations using RMI infrastructure yet specific to Spring
    • RMI (2): method invocations using RMI interfaces complying with regular RMI usage
    • RMI-IIOP (CORBA): method invocations using RMI-IIOP/CORBA
  • Enterprise JavaBean client integration
    • Local EJB stateless session bean connectivity: connecting to local stateless session beans
    • Remote EJB stateless session bean connectivity: connecting to remote stateless session beans
  • SOAP
    • Integration with the Apache Axis Web services framework
Apache CXF provides integration with the Spring Framework for RPC-style exporting of object on the server side.
Both client and server setup for all RPC-style protocols and products supported by the Spring Remote access framework (except for the Apache Axis support) is configured in the Spring Core container.
There is alternative open-source implementation (Cluster4Spring) of a remoting subsystem included into Spring Framework that is intended to support various schemes of remoting (1-1, 1-many, dynamic services discovering)…

Convention-over-configuration rapid application development

By -
Spring Boot is Spring's convention-over-configuration solution for creating stand-alone, production-grade Spring based Applications that you can "just run". It takes an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration. Create stand-alone Spring applications Embed Tomcat or Jetty directly (no need to deploy WAR files) Provide opinionated 'starter' POMs to simplify your Maven configuration Automatically configure Spring whenever possible Provide production-ready features such as metrics, health checks and externalized configuration Absolutely no code generation and no requirement for XML configuration Spring Roo provides an alternative, code-generation based approach at using convention-over-configuration to rapidly build applications in Java. It currently supports Spring Framework, Spring Security and Spring Web Flow. Roo dif...

Spring Framework

By -
Introduction The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments. The Spring Framework is an application framework and inversion of control container for the Java platform. The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE platform. Although the framework does not impose any specific programming model, it has become popular in the Java community as an alternative to, replacement for, or even addition to the Enterprise JavaBeans (EJB) model. The Spring Framework is open source. Features Dependency In...

AOP framework

By -
The Spring Framework has its own Aspect-oriented programming (AOP) framework that modularizes cross-cutting concerns in aspects. The motivation for creating a separate AOP framework comes from the belief that it would be possible to provide basic AOP features without too much complexity in either design, implementation, or configuration. The Spring AOP framework also takes full advantage of the Spring container.The Spring AOP framework is proxy pattern-based, and is configured at run time. This removes the need for a compilation step or load-time weaving. On the other hand, interception only allows for public method-execution on existing objects at a join point. Compared to the AspectJ framework, Spring AOP is less powerful, but also less complicated. Spring 1.2 includes support to configure AspectJ aspects in the container. Spring 2.0 added more integration with AspectJ; for example, the pointcut language is reused and can be mixed with Spring AOP-based aspects. Furthe...
