The document discusses different techniques for configuring beans in the Spring framework, including setting properties, dependencies, scopes, factories, initialization/destruction methods, parent/child relationships, handling events, and aspects of aspect-oriented programming. It provides examples of XML configurations for common bean definitions and properties. The document serves as a reference for the various options available in Spring's bean configuration.

9. Bean Configuration

10. <bean id="employee" class="com.all4rest.domain.Employee" />

11. <bean id="employee" class="com.all4rest.domain.Employee" >
<constructor-arg name="name" value="oleg" />
<constructor-arg name="salary" value="200.00" />
</bean>

12. <bean id="employee" class="com.all4rest.domain.Employee" >
<property name="name" value="oleg" />
</bean>

13. <bean id="salonService" class="com.all4rest.domain.SalonService" >
<property name="name" value="haircut" />
</bean>
<bean id="employee" class="com.all4rest.domain.Employee" >
<property name="salonService" ref="salonService" />
</bean>

14. <bean id="employee" class="com.all4rest.domain.Employee" >
<property name="salonService" >
<bean class="com.all4rest.domain.SalonService" />
</property>
</bean>

15. <list>, <set>, <map>, <props>
<bean id="service.haircut" class="com.all4rest.domain.SalonService" >
<property name="name" value="haircut" />
</bean>
<bean id="service.manicure" class="com.all4rest.domain.SalonService" >
<property name="name" value="manicure" />
</bean>
<bean id="employee" class="com.all4rest.domain.Employee" >
<property name="salonServices" >
<list>
<ref bean="service.haircut" />
<ref bean="service.manicure" />
</list>
</property>
</bean>

16. <bean id="employee" class="com.all4rest.domain.Employee" >
<property name="name" ><null /></property>
</bean>

17. Autowiring
(byName, byType, constructor, auto-detect)

20. Bean scoping
<bean id="employee" class="com.all4rest.domain.Employee“
scope="prototype" />
singleton
request
web
session

21. Factories
<bean id="employee" class="com.all4rest.domain.Employee“
factory-bean="employeeFactory“
factory-method="createEmployee" />

22. Initialization/Destruction methods
<bean id="employee" class="com.all4rest.domain.Employee“
init-method="employeeInit“
destroy-method="employeeDestroy" />

23. Parent/child beans
<bean id="abstractEmployee" class="com.all4rest.domain.AbstractEmployee“
abstract="true"/>
<bean id="employee" class="com.all4rest.domain.Employee“
parent="abstractEmployee" />

24. Handling Application Events
<bean id="contextRefreshListener“
class="com.all4rest.ContextRefreshListener" />
public class ContextRefreshListener implements ApplicationListener {
public void onApplicationEvent(ApplicationEvent event) {
if (event instanceof ContextRefreshedEvent) {
// do my staff
}
}
}

25. BeanNameAware
ApplicationContextAware

26. AOP
(aspect, advice, pointcut)
