The document provides an introduction to Spring Enterprise Integration. It discusses that Spring Enterprise Integration extends the Spring programming model to messaging and builds on existing enterprise integration support. It provides a higher level of abstraction and supports message-driven architectures, routing, and transformation of messages to integrate different transports and data formats. The document also summarizes the goals of Spring Integration as providing a simple model for complex integration solutions, facilitating asynchronous messaging in Spring applications, and promoting intuitive adoption for Spring users.

What is Spring Enterprise?
Spring Enterprise Integration extends the Spring programming
model into the messaging domain and builds upon Spring's existing
enterprise integration support to provide an even higher level of
abstraction. It supports message-driven architectures where
inversion of control applies to runtime concerns, such
as when certain business logic should execute and where the
response should be sent. It supports routing and transformation of
messages so that different transports and different data formats can
be integrated without impacting testability. In other words, the
messaging and integration concerns are handled by the framework,
so business components are further isolated from the infrastructure
and developers are relieved of complex integration responsibilities.

Goals of Spring Integration
Spring Integration is motivated by the following goals:
• Provide a simple model for implementing complex
enterprise integration solutions.
• Facilitate asynchronous, message-driven behavior
within a Spring-based application.
• Promote intuitive, incremental adoption for existing
Spring users.

Principles of Spring Integration
Spring Integration is guided by the following principles:
•Components should be loosely coupled for modularity
and testability.
•The framework should enforce separation of
concerns between business logic and integration logic.
•Extension points should be abstract in nature but
within well-defined boundaries to
promote reuse and portability.

What is Spring Web Services?
• Spring Web Services (Spring-WS) is a product of the
Spring community focused on creating document-
driven Web services. Spring Web Services aims to
facilitate contract-first SOAP service development,
allowing for the creation of flexible web services
using one of the many ways to manipulate XML
payloads. The product is based on Spring itself, which
means you can use the Spring concepts such as
dependency injection as an integral part of your Web
service.

What Are RESTful Web Services?
• RESTful web services are built to work best on the Web. Representational
State Transfer (REST) is an architectural style that specifies constraints, such
as the uniform interface, that if applied to a web service induce desirable
properties, such as performance, scalability, and modifiability, that enable
services to work best on the Web. In the REST architectural style, data and
functionality are considered resources and are accessed using Uniform
Resource Identifiers (URIs), typically links on the Web.
• The resources are acted upon by using a set of simple, well-defined
operations. The REST architectural style constrains an architecture to a
client/server architecture and is designed to use a stateless communication
protocol, typically HTTP. In the REST architecture style, clients and servers
exchange representations of resources by using a standardized interface and
protocol.

Introduction to the Spring Framework
• The Spring Framework is a Java platform that provides
comprehensive infrastructure support for developing Java
applications. Spring handles the infrastructure so you can focus on
your application.
• Spring enables you to build applications from "plain old Java
objects" (POJOs) and to apply enterprise services non-invasively to
POJOs. This capability applies to the Java SE programming model
and to full and partial Java EE.

Spring Batch Integration
• Many applications within the enterprise domain require bulk processing to
perform business operations in mission critical environments. These business
operations include automated, complex processing of large volumes of
information that is most efficiently processed without user interaction. These
operations typically include time based events (e.g. month-end calculations,
notices or correspondence), periodic application of complex business rules
processed repetitively across very large data sets (e.g. Insurance benefit
determination or rate adjustments), or the integration of information that is
received from internal and external systems that typically requires formatting,
validation and processing in a transactional manner into the system of record.
Batch processing is used to process billions of transactions every day for
enterprises.
• Spring Batch is a lightweight, comprehensive batch framework designed to
enable the development of robust batch applications vital for the daily
operations of enterprise systems.
