Spring Bean Autowiring Tutorial
Spring » on Sep 3, 2011 { 25 Comments } By Sivateja
Wiring a bean means configuring a bean along with its dependencies into an xml file like previous concepts, by default autowiring is disabled in spring framework. It means the programmer has to explicitly wire the bean properties into an xml file.
If autowiring is enabled then spring container will take care about injecting the dependencies, programmer no need to configure into an xml file explicitly. Autowiring is only supported if the dependancies are in the form of objects only, to enable autowiring, we should add autowire attribute to the bean element [or] bean tag, autowire has the following values
- byName
- byType
- Constructor
- autoDetect
- none
Let us see each value with one example in the next sessions
