Method Detail

get

public <T> T get(java.lang.Class<T> beanType)

Description copied from interface: BeanLocator

Returns the bean instance that matches the given object type. If the provided bean class contains a public static field NAME, this name is used to look up the bean to improve performance.

Specified by:

get in interface BeanLocator

Parameters:

beanType - type the bean must match; can be an interface or superclass. null is disallowed.

Returns:

an instance of the single bean matching the required type

get

public <T> T get(java.lang.String name)

Description copied from interface: BeanLocator

Return an instance of the specified bean.

Specified by:

get in interface BeanLocator

Parameters:

name - the name of the bean to retrieve

Returns:

bean instance

get

public <T> T get(java.lang.String name,
                 @Nullable
                 java.lang.Class<T> beanType)

Description copied from interface: BeanLocator

Returns an instance of the specified bean.

Specified by:

get in interface BeanLocator

Parameters:

name - the name of the bean to retrieve

beanType - type the bean must match. Can be an interface or superclass of the actual class, or null for any match. For example, if the value is Object.class, this method will succeed whatever the class of the returned instance.

Returns:

bean instance

getPrototype

public <T> T getPrototype(java.lang.String name,
                          java.lang.Object... args)

Description copied from interface: BeanLocator

Returns an instance of prototype bean, specifying explicit constructor arguments.

Specified by:

getPrototype in interface BeanLocator

Parameters:

name - the name of the bean to retrieve

args - constructor arguments

Returns:

bean instance

getPrototype

public <T> T getPrototype(java.lang.Class<T> beanType,
                          java.lang.Object... args)

Description copied from interface: BeanLocator

Returns an instance of prototype bean, specifying explicit constructor arguments.

Specified by:

getPrototype in interface BeanLocator

Parameters:

beanType - type the bean must match; can be an interface or superclass. null is disallowed.

args - constructor arguments

Returns:

bean instance

getAll

public <T> java.util.Map<java.lang.String,T> getAll(java.lang.Class<T> beanType)

Description copied from interface: BeanLocator

Returns the bean instances that match the given object type (including subclasses).

The Map returned by this method should always return bean names and corresponding bean instances in the order of definition in the backend configuration, as far as possible.

Specified by:

getAll in interface BeanLocator

Parameters:

beanType - the class or interface to match, or null for all concrete beans

Returns:

a Map with the matching beans, containing the bean names as keys and the corresponding bean instances as values

containsBean

public boolean containsBean(java.lang.String name)

Description copied from interface: BeanLocator

Whether a bean with the given name is present.

Specified by:

containsBean in interface BeanLocator

setApplicationContext

public void setApplicationContext(@Nonnull
                                  org.springframework.context.ApplicationContext applicationContext)
                           throws org.springframework.beans.BeansException

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware
