Batch framework

By -
Spring Batch is a framework for batch processing that provides reusable functions that are essential in processing large volumes of records, including:
  • logging/tracing
  • transaction management
  • job processing statistics
  • job restart
It also provides more advanced technical services and features that will enable extremely high-volume and high performance batch jobs through optimizations and partitioning techniques. Spring Batch is a framework for batch processing – execution of a series of jobs. In Spring Batch, A job consists of many steps and each step consists of a READ-PROCESS-WRITE task or single operation task (tasklet).
For "READ-PROCESS-WRITE" process, it means "read" data from the resources (csv, xml or database), "process" it and "write" it to other resources (csv, xml and database). For example, a step may read data from a CSV file, process it and write it into the database. Spring Batch provides many made Classes to read/write CSV, XML and database.
For "single" operation task (tasklet), it means doing single task only, like clean up the resources after or before a step is started or completed.
And the steps can be chained together to run as a job.

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...
