  Unit 1 Exploring SpringBoot
• 2.
  Syllabus Introduction to SpringFramework and SpringBoot: • Overview of Spring ecosystem • Advantages of Spring • Setting Development environment • Understanding dependency injection. Events: • Event Handling and Listeners in spring boot Staring with SpringBoot: • Spring Boot Starter project • Spring Initializer • Structure of Spring application • annotations and Configuration • YAML vs properties files • Autoconfing ,customizing auto-config • conditional annotation • CRUD operations Creating and Handling REST services: Understanding the service and microservices architecture • Service Discovery and registry • API Management and monitoring • Spring Security, O-auth

  What is springFramework? • comprehensive programming and configuration model for modern Java- based enterprise applications- on any kind of deployment platform. • 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 • Spring is a lightweight framework. • support to various frameworks such as Struts, Hibernate, Tapestry, EJB, JSF, etc. • The framework, in broader sense, can be defined as a structure where we find solution of the various technical problems. • The Spring framework comprises several modules such as IOC, AOP, DAO, Context, ORM, WEB MVC etc.

  What is springFramework? • Make a Java method execute in a database transaction without having to deal with transaction APIs. • Make a local Java method a remote procedure without having to deal with remote APIs. • Make a local Java method a management operation without having to deal with JMX APIs. • Make a local Java method a message handler without having to deal with JMS APIs.
• 6.
  Core Container • CoreContainer consists of the Core, Beans, Context, and Expression Language modules. • The Core and Beans modules provide the fundamental parts of the framework, including the IoC and Dependency Injection features. • The BeanFactory is a sophisticated implementation of the factory pattern. • The Context module inherits its features from the Beans module and adds support for internationalization (using, for example, resource bundles), event-propagation, resource-loading, and the transparent creation of contexts by, for example, a servlet container. • The Context module also supports Java EE features such as EJB, JMX ,and basic remoting. The ApplicationContext interface is the focal point of the Context module. • The Expression Language module provides a powerful expression language for querying and manipulating an object graph at runtime. • It is an extension of the unified expression language (unified EL) as specified in the JSP 2.1 specification. The language supports setting and getting property values, property assignment, method invocation, accessing the context of arrays, collections and indexers, logical and arithmetic operators, named variables, and retrieval of objects by name from Spring's IoC container. It also supports list projection and selection as well as common list aggregations.

  Data Access/Integration • TheData Access/Integration layer consists of the JDBC, ORM, OXM, JMS and Transaction modules. • The JDBC module provides a JDBC-abstraction layer that removes the need to do tedious JDBC coding and parsing of database-vendor specific error codes. • The ORM module provides integration layers for popular object-relational mapping APIs, including JPA, JDO, Hibernate, and iBatis. • The OXM module provides an abstraction layer that supports Object/XML mapping implementations for JAXB, Castor, XMLBeans, JiBX and XStream. • The Java Messaging Service (JMS) module contains features for producing and consuming messages. • The Transaction module supports programmatic and declarative transaction management for classes that implement special interfaces and for all your POJOs (plain old Java objects).
• 8.
  Web • The Weblayer consists of the Web, Web-Servlet, Web-Struts, and Web-Portlet modules. • Spring's Web module provides basic web-oriented integration features such as multipart file-upload functionality and the initialization of the IoC container using servlet listeners and a web-oriented application context. It also contains the web-related parts of Spring's remoting support. • The Web-Servlet module contains Spring's model-view-controller (MVC) implementation for web applications. Spring's MVC framework provides a clean separation between domain model code and web forms, and integrates with all the other features of the Spring Framework. • The Web-Struts module contains the support classes for integrating a classic Struts web tier within a Spring application. Note that this support is now deprecated as of Spring 3.0. Consider migrating your application to Struts 2.0 and its Spring integration or to a Spring MVC solution. • The Web-Portlet module provides the MVC implementation to be used in a portlet environment and mirrors the functionality of Web-Servlet module.
• 9.
  AOP and Instrumentation •Spring's AOP module provides an AOP Alliance-compliant aspect- oriented programming implementation allowing you to define, for example, method-interceptors and pointcuts to cleanly decouple code that implements functionality that should be separated. • Using source-level metadata functionality, you can also incorporate behavioral information into your code, in a manner similar to that of .NET attributes. • The separate Aspects module provides integration with AspectJ. • The Instrumentation module provides class instrumentation support and classloader implementations to be used in certain application servers.
