Dear readers, these Spring Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of Spring. As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer What is Spring Spring is an open source development framework for enterprise Java. The core features of the Spring Framework can be used in developing any Java application, but there are extensions for building web applications on top of the Java EE platform. Spring framework targets to make J2. EE development easier to use and promote good programming practice by enabling a POJO based programming model. Spring Load List From Properties File' title='Spring Load List From Properties File' />What are benefits of using spring Following is the list of few of the great benefits of using Spring Framework Lightweight Spring is lightweight when it comes to size and transparency. The basic version of spring framework is around 2. MB. Inversion of control IOC Loose coupling is achieved in spring using the technique Inversion of Control. The objects give their dependencies instead of creating or looking for dependent objects. Since the first version of this article was published in October, 2003, the Spring Framework has steadily grown in popularity. It has progressed through version 1. Aspect oriented AOP Spring supports Aspect oriented programming and enables cohesive development by separating application business logic from system services. Container Spring contains and manages the life cycle and configuration of application objects. MVC Framework Springs web framework is a well designed web MVC framework, which provides a great alternative to web frameworks such as Struts or other over engineered or less popular web frameworks. Transaction Management Spring provides a consistent transaction management interface that can scale down to a local transaction using a single database, for example and scale up to global transactions using JTA, for example. Exception Handling Spring provides a convenient API to translate technology specific exceptions thrown by JDBC, Hibernate, or JDO, for example into consistent, unchecked exceptions. What are the different modules in Spring frameworkFollowing are the modules of the Spring framework Core module. Bean module. Context module. Expression Language module. JDBC module. ORM module. OXM module. Java Messaging ServiceJMS module. Transaction module. Web module. Web Servlet module. Din Cond Black Font there. Web Struts module. Spring Interview Questions Learn Java Spring Framework version 4. Web Portlet module What is Spring configuration file Spring configuration file is an XML file. This file contains the classes information and describes how these classes are configured and introduced to each other. What is Dependency InjectionInversion of Control Io. C is a general concept, and it can be expressed in many different ways and Dependency Injection is merely one concrete example of Inversion of Control. This concept says that you do not create your objects but describe how they should be created. You dont directly connect your components and services together in code but describe which services are needed by which components in a configuration file. A container the IOC container is then responsible for hooking it all up. What are the different types of Io. C dependency injection Types of Io. C are Constructor based dependency injection Constructor based DI is accomplished when the container invokes a class constructor with a number of arguments, each representing a dependency on other class. Setter based dependency injection Setter based DI is accomplished by the container calling setter methods on your beans after invoking a no argument constructor or no argument static factory method to instantiate your bean. Which DI would you suggest Constructor based or setter based DI Since you can mix both, Constructor and Setter based DI, it is a good rule of thumb to use constructor arguments for mandatory dependencies and setters for optional dependencies. Note that the use of a Required annotation on a setter can be used to make setters required dependencies. What are the benefits of IOCThe main benefits of IOC or dependency injection are It minimizes the amount of code in your application. It makes your application easy to test as it doesnt require any singletons or JNDI lookup mechanisms in your unit test cases. Loose coupling is promoted with minimal effort and least intrusive mechanism. IOC containers support eager instantiation and lazy loading of services. What is AOP Aspect oriented programming, or AOP, is a programming technique that allows programmers to modularize crosscutting concerns, or behavior that cuts across the typical divisions of responsibility, such as logging and transaction management. The core construct of AOP is the aspect, which encapsulates behaviors affecting multiple classes into reusable modules. What is Spring Io. C container The Spring Io. C creates the objects, wire them together, configure them, and manage their complete lifecycle from creation till destruction. The Spring container uses dependency injection DI to manage the components that make up an application. What are types of Io. C containers Explain them. There are two types of Io. C containers Bean Factory container This is the simplest container providing basic support for DI. The Bean. Factory is usually preferred where the resources are limited like mobile devices or applet based applications. Spring Application. Context Container This container adds more enterprise specific functionality such as the ability to resolve textual messages from a properties file and the ability to publish application events to interested event listeners. Give an example of Bean. Factory implementation. Effective Negotiation In Purchasing And Supply Pdf more. The most commonly used Bean. Program Osis Terbaik here. Factory implementation is the Xml. Bean. Factory class. This container reads the configuration metadata from an XML file and uses it to create a fully configured system or application. What are the common implementations of the Application. Context The three commonly used implementation of Application Context are File. System. Xml. Application. Context This container loads the definitions of the beans from an XML file. Here you need to provide the full path of the XML bean configuration file to the constructor. Class. Path. Xml. Application. Context This container loads the definitions of the beans from an XML file. Here you do not need to provide the full path of the XML file but you need to set CLASSPATH properly because this container will look bean configuration XML file in CLASSPATH. Web. Xml. Application. Context This container loads the XML file with definitions of all beans from within a web application. What is the difference between Bean Factory and Application. Context Following are some of the differences Application contexts provide a means for resolving text messages, including support for i. Application contexts provide a generic way to load file resources, such as images. Application contexts can publish events to beans that are registered as listeners. Certain operations on the container or beans in the container, which have to be handled in a programmatic fashion with a bean factory, can be handled declaratively in an application context. The application context implements Message. Source, an interface used to obtain localized messages, with the actual implementation being pluggable.
