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

313 This is an automagical process in which bean references don't need

315 Spring container works out dependencies.
320 The traditional Spring default. No automagical wiring. Bean references
321 must be defined in the XML file via the <ref/> element (or "ref"
322 attribute). We recommend this in most cases as it makes documentation
326 Autowiring by property name. If a bean of class Cat exposes a "dog"
327 property, Spring will try to set this to the value of the bean "dog"
328 in the current container. If there is no matching bean by name, nothing
329 special happens; use dependency-check="objects" to raise an error in
333 Autowiring if there is exactly one bean of the property type in the
334 container. If there is more than one, a fatal error is raised, and
335 you cannot use byType autowiring for that bean. If there is none,
336 nothing special happens; use dependency-check="objects" to raise an
340 Analogous to "byType" for constructor arguments. If there is not exactly
341 one bean of the constructor argument type in the bean factory, a fatal
345 Chooses "constructor" or "byType" through introspection of the bean
346 class. If a default constructor is found, "byType" gets applied.
348 Note that explicit dependencies, i.e. "property" and "constructor-arg"
349 elements, always override autowiring. Autowire behavior can be combined
350 with dependency checking, which will be performed after all autowiring

453 to a constructor. However, it may be on a different class. In that case,

786 Contains a string representation of a property value.
787 The property may be a string, or may be converted to the required
788 type using the JavaBeans PropertyEditor machinery. This makes it
789 possible for application developers to write custom PropertyEditor
790 implementations that can convert strings to arbitrary target objects.
792 Note that this is recommended for simple objects only. Configure
793 more complex objects by populating JavaBean properties with
794 references to other beans.
