SpringAdapter()

Method Summary

static Component	adapt(Component c, SpringContext ctxt, Component transaction_manager, Component transaction_attributes, java.lang.String[] interfaces) Decorate a Component with spring context so that dependencies can be injected automatically, and FactoryBean can be automatically instantiated.

static java.lang.Object	injectBean(java.lang.Object obj, SpringContext ctxt, org.springframework.transaction.PlatformTransactionManager transaction_manager, java.util.Properties transaction_attributes, java.lang.String[] interfaces) Inject spring dependencies into an object when it is of any Spring marker interface.

injectBean

public static java.lang.Object injectBean(java.lang.Object obj,
                                          SpringContext ctxt,
                                          org.springframework.transaction.PlatformTransactionManager transaction_manager,
                                          java.util.Properties transaction_attributes,
                                          java.lang.String[] interfaces)
                                   throws java.lang.Exception

Inject spring dependencies into an object when it is of any Spring marker interface. Run FactoryBean if any. Add transaction proxy if any.

Parameters:

obj - the object to inject dependencies.

ctxt - the SpringContext object hosting all pertinent runtime information.

transaction_manager - the Component that instantiates the transaction manager. Can be null if transaction_attributes is null.

transaction_attributes - the Component that instantiates a Properties object that contains transaction attributes. This is the indicator parameter. When it is null, no transaction proxying is done. And when it is not null, the transaction_manager cannot be null.

interfaces - the interface names to proxy on. Can be null.

Returns:

the final result object.

Throws:

java.lang.Exception

adapt

public static Component adapt(Component c,
                              SpringContext ctxt,
                              Component transaction_manager,
                              Component transaction_attributes,
                              java.lang.String[] interfaces)

Decorate a Component with spring context so that dependencies can be injected automatically, and FactoryBean can be automatically instantiated.

Parameters:

c - the Component object.

ctxt - the SpringContext object.

transaction_manager - the Component that instantiates the transaction manager. Can be null if transaction_attributes is null.

transaction_attributes - the Component that instantiates a Properties object that contains transaction attributes. This is the indicator parameter. When it is null, no transaction proxying is done. And when it is not null, the transaction_manager cannot be null.

interfaces - the interface names to proxy on. Can be null.

Returns:

the new Component that does all the spring-related work.

getFactoryBean

public static org.springframework.beans.factory.FactoryBean getFactoryBean(Container yan,
                                                                           java.lang.Object key)

Get FactoryBean instance from a Spring integrated Container object.

Parameters:

yan - the Container object.

key - the key of the FactoryBean component. The key doesn't need to be prefixed with a '&' as one has to do in Spring.

Returns:

the FactoryBean instance.
