How to autowire things in spring

In order to autowire something the following things must be true (that i know of)

• - The object you are autowiring needs to be annotated with @Component
• - The object that will contain the autowired object needs to come from the spring context, meaning:
• - applicationContext.xml needs to have a bean definition of it
• - the place where its is newed  needs to be replaced with the call to pull it from the WebApplicationContext
