We also enable statistics and format generated sql statements. Session Level Metrics i. It understands that we would want to talk to an in memory database. It auto configures a datasource and also a JdbcTemplate connecting to that datasource.
This method is executed as soon as the application is launched up. Override public void run String If the entity is already present in the database, it is updated.
Else, it is inserted. Example 1 - Relationships ManyToMany Relationships between objects are expressed in a different way compared to relationship between tables. Each Employee can have multiple Tasks. Each Task can be shared by multiple Employees. There is a Many to Many relationship between them.
We use ManyToMany annotation to establish the relationship. In these situations, we define a inheritance strategy. In this example, we use a strategy of InheritanceType. The Web module also eases the tasks of handling multi-part requests and binding request parameters to domain objects. What is AOP? How does it relate with IOC?
What are different tools to utilize AOP?
A: 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. AOP and IOC are complementary technologies in that both apply a modular approach to complex problems in enterprise application development. In a typical object-oriented development approach you might implement logging functionality by putting logger statements in all your methods and Java classes.
In an AOP approach you would instead modularize the logging services and apply them declaratively to the components that required logging. The advantage, of course, is that the Java class doesn't need to know about the existence of the logging service or concern itself with any related code.

As a result, application code written using Spring AOP is loosely coupled. However AspectJ works at he byte code level and you need to use AspectJ compiler to get the AOP features built into your compiled code. Nevertheless AOP functionality is fully integrated into the Spring context for transaction management, logging, and various other features. In general any AOP framework control aspects in three possible ways: Joinpoints: Points in a program's execution.
For example, joinpoints could define calls to specific methods in a class Pointcuts: Program constructs to designate joinpoints and collect specific context at those points Advices: Code that runs upon meeting certain conditions.

For example, an advice could log a message before executing a joinpoint Q. What are the advantages of spring framework?

POJO programming enables continuous integration and testability. Explain BeanFactory in spring. A: Bean factory is an implementation of the factory design pattern and its function is to create and dispense beans.
As the bean factory knows about many objects within an application, it is able to create association between collaborating objects as they are instantiated. This removes the burden of configuration from the bean and the client.
There are several implementation of BeanFactory. The most useful one is "org. The resource will provide the XML to the factory. The bean definition includes the description of beans and their properties.

But the bean factory doesn't instantiate the bean yet. To retrieve a bean from a 'BeanFactory', the getBean method is called.Hibernate does not support lazy initialization for detached objects.
