  8. Spring XML Beans Schema, version 2.0
  9. Authors: Rob Harrop, Juergen Hoeller
  10. This defines a simple and consistent way of creating a namespace
  11. of JavaBeans objects, managed by a Spring BeanFactory, read by
  12. XmlBeanDefinitionReader (with DefaultBeanDefinitionDocumentReader).
  13. This document type is used by most Spring functionality, including
  14. web application contexts, which are based on bean factories.
  15. Each "bean" element in this document defines a JavaBean.
  16. Typically the bean class is specified, along with JavaBean properties
  17. and/or constructor arguments.
  18. A bean instance can be a "singleton" (shared instance) or a "prototype"
  19. (independent instance). Further scopes can be provided by extended
  20. bean factories, for example in a web environment.
  21. References among beans are supported, that is, setting a JavaBean property
  22. or a constructor argument to refer to another bean in the same factory
  23. (or an ancestor factory).
  24. As alternative to bean references, "inner bean definitions" can be used.
  25. Singleton flags of such inner bean definitions are effectively ignored:
  26. inner beans are typically anonymous prototypes.
  27. There is also support for lists, sets, maps, and java.util.Properties
  28. as bean property types or constructor argument types.

  293. The traditional Spring default. No automagical wiring. Bean references
  294. must be defined in the XML file via the <ref/> element (or "ref"
  295. attribute). We recommend this in most cases as it makes documentation
  296. more explicit.
  297. 2. "byName"
  298. Autowiring by property name. If a bean of class Cat exposes a "dog"
  299. property, Spring will try to set this to the value of the bean "dog"
  300. in the current container. If there is no matching bean by name, nothing
  301. special happens; use dependency-check="objects" to raise an error in
  302. that case.
  303. 3. "byType"
  304. Autowiring if there is exactly one bean of the property type in the
  305. container. If there is more than one, a fatal error is raised, and
  306. you cannot use byType autowiring for that bean. If there is none,
  307. nothing special happens; use dependency-check="objects" to raise an
  308. error in that case.
  309. 4. "constructor"
  310. Analogous to "byType" for constructor arguments. If there is not exactly
  311. one bean of the constructor argument type in the bean factory, a fatal
  312. error is raised.
  313. 5. "autodetect"
  314. Chooses "constructor" or "byType" through introspection of the bean
  315. class. If a default constructor is found, "byType" gets applied.
  316. Note that explicit dependencies, i.e. "property" and "constructor-arg"
  317. elements, always override autowiring. Autowire behavior can be combined
  318. with dependency checking, which will be performed after all autowiring
  319. has been completed.
  320. Note: This attribute will not be inherited by child bean definitions.
  321. Hence, it needs to be specified per concrete bean definition.
