Question: What do you mean by Bean wiring ?

Answer: The act of creating associations between application components (beans) within the Spring container is reffered to as Bean wiring. Source: CoolInterview.com
Question: What are the ways to access Hibernate using Spring ?

Answer: There are two approaches to Spring?s Hibernate integration:

* Inversion of Control with a HibernateTemplate and Callback
* Extending HibernateDaoSupport and Applying an AOP Interceptor Source: CoolInterview.com
Question: What are the advantages of Spring framework?

Answer: The advantages of Spring are as follows:

* Spring has layered architecture. Use what you need and leave you don't need now.
* Spring Enables POJO Programming. There is no behind the scene magic here. POJO programming enables continuous integration and testability.
* Dependency Injection and Inversion of Control Simplifies JDBC
* Open source and no vendor lock-in.

Question: Explain about the different ways in which Spring JDBC can help you?

Answer: There are several ways in which a spring JDBC can help you they are: -
1) Connection leaks can be avoided.
2) Code can be focused on necessary SQL and it is very low.
3) Applications will never have to depend on RDBMS error specification handling.
4) You can easily implement DAO pattern without business logic. Source: CoolInterview.com
Question: Explain about portability of spring?

Answer: Spring applications and framework are portable between different servers. This framework and applications are portable between many different servers such as Tomcat, Jetty, Web Logic, Web Sphere, Resin, Geronimo, etc. Environment features can be implemented without affecting portability. Source: CoolInterview.com
Question: What is Bean Factory ?

Answer: A BeanFactory is like a factory class that contains a collection of beans. The BeanFactory holds Bean Definitions of multiple beans within itself and then instantiates the bean whenever asked for by clients.

* BeanFactory is able to create associations between collaborating objects as they are instantiated. This removes the burden of configuration from bean itself and the beans client.
* BeanFactory also takes part in the life cycle of a bean, making calls to custom initializat Source: CoolInterview.com
Question: Explain the three different methods which are provided by the Namespace Handler interface?

Answer: The three different methods which are provided by the name space handler interface are: -
1) Init() is used to allow initialization for name space handler.
2) BeanDefinition parse is used when a Spring encounters a top level element.
3) BeanDefinitionHandler is used when spring encounters an attribute. Source: CoolInterview.com
Question: What are the advantages of spring framework?

Answer: Hibernate can be accessed in the following two ways:

By IOC with a Callback and HibernateTemplate.
By applying an AOP Interceptor and broadening the HibernateDaoSupport. Source: CoolInterview.com
Question: What is Metadata Autoproxying ?

Answer: Metadata Autoproxying can be performed inspiring which can be driven by metadata. This is determined by source level attributes and keeps metadata inside the source code.

This maintains metadata in one place and mainly used for declarative transaction support. Source: CoolInterview.com
Question: Explain the advantages of using DAO module?

Answer: The database code can be kept clean and simple by using the DAO module. This helps in preventing problems that rise because of poor handling of closures of database resources. Also, the DAO module utilizes the AOP module to enable objects in the Spring application to use transaction management services. Source: CoolInterview.com
Question: What is SQLExceptionTranslator ?

Answer: SQLExceptionTranslator, is an interface to be implemented by classes that can translate between SQLExceptions and Spring's own data-access-strategy-agnostic org.springframework.dao.DataAccessException. Source: CoolInterview.com
Question: What is Significance of JSF- Spring integration ?

Answer: Spring - JSF integration is useful when an event handler wishes to explicitly invoke the bean factory to create beans on demand, such as a bean that encapsulates the business logic to be performed when a submit button is pressed. Source: CoolInterview.com
Question: What are the benefits of the Spring Framework transaction management ?

Answer: The Spring Framework provides a consistent abstraction for transaction management that delivers the following benefits:

* Provides a consistent programming model across different transaction APIs such as JTA, JDBC, Hibernate, JPA, and JDO.
* Supports declarative transaction management.
* Provides a simpler API for programmatic transaction management than a number of complex transaction APIs such as JTA.
* Integrates very well with Spring's various data access Source: CoolInterview.com
Question: Explain about exception wrapping?

Answer: Wrapping can be effectively done using spring. It makes the proprietary code to run in the ORM layer to a set of abstracted run time exceptions. Persistence exceptions can be easily handled. Handling of exceptions can be done very easily. Source: CoolInterview.com
Question: What are the benefits of IOC (Dependency Injection)?

Answer: Benefits of IOC (Dependency Injection) are as follows:

*

Minimizes the amount of code in your application. With IOC containers you do not care about how services are created and how you get references to the ones you need. You can also easily add additional services by adding a new constructor or a setter method with little or no extra configuration.
*

Make your application more testable by not requiring any singletons or JNDI lookup mechanisms in your Source: CoolInterview.com
Question: What is cross cutting concern and concern in spring AOP ?

Answer: Cross cutting concern: It is a concern which is applicable throughout the application and it affects the entire application. E.g Security, logging and data transfer are the concerns which are needed in almost every module of an application.

Concern: Concern is a behavior that we want to have in a module of an application. Issues in which we are interested defines our concern . Source: CoolInterview.com
Question: What are the types of Dependency Injection?

Answer: Two types of dependency injection are supported by spring framework:

Setter Injection
Constructor Injection Source: CoolInterview.com
Question: What is SQLProvider ?

Answer: SQLProvider:
* Has one method ? getSql()
* Typically implemented by PreparedStatementCreator implementers.
* Useful for debugging. Source: CoolInterview.com
Question: What is the typical Bean life cycle in Spring Bean Factory Container ?

Answer: Bean life cycle in Spring Bean Factory Container is as follows:

*

The spring container finds the bean?s definition from the XML file and instantiates the bean.
*

Using the dependency injection, spring populates all of the properties as specified in the bean definition
*

If the bean implements the BeanNameAware interface, the factory calls setBeanName() passing the bean?s ID.
*

If the bean implements the BeanFacto Source: CoolInterview.com
Question: How is a typical spring implementation look like ?

Answer: For a typical Spring Application we need the following files:

*

An interface that defines the functions.
*

An Implementation that contains properties, its setter and getter methods, functions etc.,
*

Spring AOP (Aspect Oriented Programming)
*

A XML file called Spring configuration file.
*

Client program that uses the function.
