Class PropertiesBeanDefinitionReader

java.lang.Object
  org.springframework.beans.factory.support.AbstractBeanDefinitionReader
      org.springframework.beans.factory.support.PropertiesBeanDefinitionReader

All Implemented Interfaces:: BeanDefinitionReader

public class PropertiesBeanDefinitionReader
extends AbstractBeanDefinitionReader
extends AbstractBeanDefinitionReader

Bean definition reader for a simple properties format.

Provides bean definition registration methods for Map/Properties and ResourceBundle. Typically applied to a DefaultListableBeanFactory.

Example:

employee.(class)=MyClass       // bean is of class MyClass
 employee.(abstract)=true       // this bean can't be instantiated directly
 employee.group=Insurance       // real property
 employee.usesDialUp=false      // real property (potentially overridden)

 salesrep.(parent)=employee     // derives from "employee" bean definition
 salesrep.(lazy-init)=true      // lazily initialize this singleton bean
 salesrep.manager(ref)=tony     // reference to another bean
 salesrep.department=Sales      // real property

 techie.(parent)=employee       // derives from "employee" bean definition
 techie.(singleton)=false       // bean is a prototype (not a shared instance)
 techie.manager(ref)=jeff       // reference to another bean
 techie.department=Engineering  // real property
 techie.usesDialUp=true         // real property (overriding parent value)

ceo.$0(ref)=secretary // inject 'secretary' bean as 0th constructor arg ceo.$1=1000000 // inject value '1000000' at 1st constructor arg Note: As of Spring 1.2.6, the use of class and parent has been deprecated in favor of (class) and (parent), for consistency with all other special properties. Users should note that support for class and parent as special properties rather then actual bean properties will be removed in a future version.

Constructor Detail

PropertiesBeanDefinitionReader

public PropertiesBeanDefinitionReader(BeanDefinitionRegistry beanFactory)

Create new PropertiesBeanDefinitionReader for the given bean factory.

Method Detail

setDefaultParentBean

public void setDefaultParentBean(String defaultParentBean)

Set the default parent bean for this bean factory. If a child bean definition handled by this factory provides neither a parent nor a class attribute, this default value gets used.

Can be used e.g. for view definition files, to define a parent with a default view class and common attributes for all views. View definitions that define their own parent or carry their own class can still override this.

Strictly speaking, the rule that a default parent setting does not apply to a bean definition that carries a class is there for backwards compatiblity reasons. It still matches the typical use case.

getDefaultParentBean

public String getDefaultParentBean()

Return the default parent bean for this bean factory.

setPropertiesPersister

public void setPropertiesPersister(PropertiesPersister propertiesPersister)

Set the PropertiesPersister to use for parsing properties files. The default is DefaultPropertiesPersister.

See Also:: DefaultPropertiesPersister

getPropertiesPersister

public PropertiesPersister getPropertiesPersister()

Return the PropertiesPersister to use for parsing properties files.

loadBeanDefinitions

public int loadBeanDefinitions(Resource resource)
                        throws BeansException

Load bean definitions from the specified properties file, using all property keys (i.e. not filtering by prefix).

Parameters:: resource - the resource descriptor for the properties file
Returns:: the number of bean definitions found
Throws:: BeansException - in case of loading or parsing errors
See Also:: loadBeanDefinitions(org.springframework.core.io.Resource, String)

loadBeanDefinitions

                               String prefix)
                        throws BeansException

Load bean definitions from the specified properties file.

Parameters:: resource - the resource descriptor for the properties file; prefix - match or filter within the keys in the map: e.g. 'beans.' (can be empty or null)
Returns:: the number of bean definitions found
Throws:: BeansException - in case of loading or parsing errors

loadBeanDefinitions

public int loadBeanDefinitions(EncodedResource encodedResource)
