All Implemented Interfaces:
Cloneable, BeanDefinition, BeanMetadataElement, AttributeAccessor, Serializable
Bean definition for beans which inherit settings from their parent.
Child bean definitions have a fixed dependency on a parent bean definition.
A child bean definition will inherit constructor argument values,
property values and method overrides from the parent, with the option
to add new values. If init method, destroy method and/or static factory
method are specified, they will override the corresponding parent settings.
The remaining settings will always be taken from the child definition:
depends on, autowire mode, dependency check, singleton, lazy init.
NOTE: Since Spring 2.5, the preferred way to register bean
definitions programmatically is the GenericBeanDefinition class,
which allows to dynamically define parent dependencies through the
GenericBeanDefinition#setParentName method. This effectively
supersedes the ChildBeanDefinition class for most use cases.
| Constructor: |
|---|
 public ChildBeanDefinition(String parentName) {
super();
this.parentName = parentName;
}
Create a new ChildBeanDefinition for the given parent, to be
configured through its bean properties and configuration methods. |
public ChildBeanDefinition(ChildBeanDefinition original) {
super((BeanDefinition) original);
} Create a new ChildBeanDefinition as deep copy of the given
bean definition. Parameters:
original - the original bean definition to copy from
|
public ChildBeanDefinition(String parentName,
MutablePropertyValues pvs) {
super(null, pvs);
this.parentName = parentName;
} Create a new ChildBeanDefinition for the given parent. Parameters:
parentName - the name of the parent bean
pvs - the additional property values of the child
|
public ChildBeanDefinition(String parentName,
ConstructorArgumentValues cargs,
MutablePropertyValues pvs) {
super(cargs, pvs);
this.parentName = parentName;
} Create a new ChildBeanDefinition for the given parent. Parameters:
parentName - the name of the parent bean
cargs - the constructor argument values to apply
pvs - the additional property values of the child
|
public ChildBeanDefinition(String parentName,
Class beanClass,
ConstructorArgumentValues cargs,
MutablePropertyValues pvs) {
super(cargs, pvs);
this.parentName = parentName;
setBeanClass(beanClass);
} Create a new ChildBeanDefinition for the given parent,
providing constructor arguments and property values. Parameters:
parentName - the name of the parent bean
beanClass - the class of the bean to instantiate
cargs - the constructor argument values to apply
pvs - the property values to apply
|
public ChildBeanDefinition(String parentName,
String beanClassName,
ConstructorArgumentValues cargs,
MutablePropertyValues pvs) {
super(cargs, pvs);
this.parentName = parentName;
setBeanClassName(beanClassName);
} Create a new ChildBeanDefinition for the given parent,
providing constructor arguments and property values.
Takes a bean class name to avoid eager loading of the bean class. Parameters:
parentName - the name of the parent bean
beanClassName - the name of the class to instantiate
cargs - the constructor argument values to apply
pvs - the property values to apply
