I am new to spring and I wanted to ask whether or not it is possible to pass params to the init and destroy methods of a bean.
Thanks.

To define setup and teardown for a bean, we simply declare the <bean> with initmethod and/or destroy-method parameters. The init-method attribute specifies a method that is to be called on the bean immediately upon instantiation.
destroyMethod. The optional name of a method to call on the bean instance upon closing the application context, for example a close() method on a JDBC DataSource implementation, or a Hibernate SessionFactory object.
One of the ways to run your code right after a Bean has been initialized is to use @PostConstract annotation. In the below code example the class MyBean is annotated with @Component annotation. This Bean will be created at application startup time. Note the use of @PostConstruct annotation.
Just like applets, servlets can define init() and destroy() methods. A servlet's init(ServletConfig) method is called by the server immediately after the server constructs the servlet's instance. Depending on the server and its configuration, this can be at any of these times: When the server starts.
No, you can't. If you need parameters, you will have to inject them as fields beforehand.
Sample Bean
public class Foo{
@Autowired
private Bar bar;
public void init(){
bar.doSomething();
}
}
Sample XML:
<bean class="Foo" init-method="init" />
