Spring Interview Questions - Three

Q1: What are types of IoC containers? Explain them.

Ans: There are two types of IoC containers:

• Bean Factory container: This is the simplest container providing basic support for DI .The BeanFactory is usually preferred where the resources are limited like mobile devices or applet based applications
• Spring ApplicationContext 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.

·     Q2: Give an example of BeanFactory implementation.

·    Ans: The most commonly used BeanFactory implementation is the XmlBeanFactory class. This container reads the configuration metadata from an XML file and uses it to create a fully configured system or application.

·     Q3: What are the common implementations of the ApplicationContext?

·     Ans: The three commonly used implementation of 'Application Context' are:

• FileSystemXmlApplicationContext: 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.
• ClassPathXmlApplicationContext: 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.
• WebXmlApplicationContext: This container loads the XML file with definitions of all beans from within a web application. 

Q4: What is the difference between Bean Factory and ApplicationContext?

A: Following are some of the differences:

1. Application contexts provide a means for resolving text messages, including support for i18n of those messages.
2. Application contexts provide a generic way to load file resources, such as images.
3. Application contexts can publish events to beans that are registered as listeners.
4. 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.
5. The application context implements MessageSource, an interface used to obtain localized messages, with the actual implementation being pluggable.

Q5: What are Spring beans?

Ans: The objects that form the backbone of your application and that are managed by the Spring IoC container are called beans. A bean is an object that is instantiated, assembled, and otherwise managed by a Spring IoC container. These beans are created with the configuration metadata that you supply to the container, for example, in the form of XML <bean/> definitions.

Q6: What does a bean definition contain?

Ans: The bean definition contains the information called configuration metadata which is needed for the container to know the followings:

•          How to create a bean
•          Bean's lifecycle details
•          Bean's dependencies

Q7: How do you provide configuration metadata to the Spring Container?

Ans: There are following three important methods to provide configuration metadata to the Spring Container:

•          XML based configuration file.
•          Annotation-based configuration
•          Java-based configuration

Q8: How do add a bean in spring application?

Ans: Check the following example:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

   <bean id="helloWorld" class="com.tutorialspoint.HelloWorld">

       <property name="message" value="Hello World!"/>

   </bean>

</beans>

Q9: How do you define a bean scope?

Ans: When defining a <bean> in Spring, you have the option of declaring a scope for that bean. For example, to force Spring to produce a new bean instance each time one is needed, you should declare the bean's scope attribute to be prototype. Similar way if you want Spring to return the same bean instance each time one is needed, you should declare the bean's scope attribute to besingleton. 

Hibernate Interview Questions - Three

Q1. Should all the mapping files of hibernate have .hbm.xml extension to work properly?

Ans: No, having .hbm.xml extension is a convention and not a requirement for hibernate mapping file names. We can have any extension for these mapping files. But this is the best practice to follow this extension.

Q2. How do we create session factory in hibernate?

Ans: To create a session factory in hibernate, an object of configuration is created first which refers to the path of configuration file and then for that configuration, session factory is created as given in the example below:

Configuration config = new Configuration();
config.addResource(&amp;quot;myinstance/configuration.hbm.xml&amp;quot;);
config.setProperties( System.getProperties() );
SessionFactory sessions = config.buildSessionFactory();

Q3. What is meant by Method chaining?

Ans: Method chaining is a programming technique that is supported by many hibernate interfaces. This is less readable when compared to actual java code. And it is not mandatory to use this format. Look how a SessionFactory is created when we use method chaining.

SessionFactory sessions = new Configuration()
.addResource(“myinstance/MyConfig.hbm.xml”)
.setProperties( System.getProperties() )
.buildSessionFactory();

Q4. What does hibernate.properties file consist of?

Ans: This is a property file that should be placed in application class path. So when the Configuration object is created, hibernate is first initialized. At this moment the application will automatically detect and read this hibernate.properties file.

hibernate.connection.datasource = java:/comp/env/jdbc/AuctionDB
hibernate.transaction.factory_class = net.sf.hibernate.transaction.JTATransactionFactory
hibernate.transaction.manager_lookup_class = net.sf.hibernate.transaction.JBossTransactionManagerLookup
hibernate.dialect = net.sf.hibernate.dialect.PostgreSQLDialect

Q5. What should SessionFactory be placed so that it can be easily accessed?

Ans: As far as it is compared to J2EE environment, if the SessionFactory is placed in JNDI then it can be easily accessed and shared between different threads and various components that are hibernate aware. You can set the SessionFactory to a JNDI by configuring a property hibernate.session_factory_name in the hibernate.properties file.

Q6. What are POJOs and what’s their significance?

Ans: POJO stands for plain old java objects. These are just basic JavaBeans that have defined setter and getter methods for all the properties that are there in that bean. Besides they can also have some business logic related to that property. Hibernate applications works efficiently with POJOs rather than simple java classes. Use of POJOs instead of simple java classes results in an efficient and well-constructed code.

Q7. What is ORM metadata?

Ans: ORM tools require a metadata format for the application to specify the mapping between classes and tables, properties and columns, associations and foreign keys, Java types and SQL types. This information is called the object/relational mapping metadata. It defines the transformation between the different data type systems and relationship representations.

Q8. What’s HQL?

Ans: HQL is the query language used in Hibernate which is an extension of SQL. HQL is very efficient, simple and flexible query language to do various types of operations on relational database without writing complex database queries.

Q9. What are the different types of property and class mappings?

• Typical and most common property mapping
<property name=”description” column=”DESCRIPTION” type=”string”/>
Or 
<property name=”description” type=”string”>
<column name=”DESCRIPTION”/>
</property>
• Derived properties
<property name=”averageBidAmount” formula=”( select AVG(b.AMOUNT) from BID b
where b.ITEM_ID = ITEM_ID )” type=”big_decimal”/>
• Typical and most common property mapping
<property name=”description” column=”DESCRIPTION” type=”string”/>
• Controlling inserts and updates
<property name=”name” column=”NAME” type=”string”
insert=”false” update=”false”/>
