Class TransactionInterceptor

java.lang.Object

org.springframework.transaction.interceptor.TransactionAspectSupport

org.springframework.transaction.interceptor.TransactionInterceptor

All Implemented Interfaces:

java.io.Serializable, Advice, Interceptor, MethodInterceptor, Aware, BeanFactoryAware, InitializingBean

public class TransactionInterceptor
extends TransactionAspectSupport
implements MethodInterceptor, java.io.Serializable

AOP Alliance MethodInterceptor for declarative transaction management using the common Spring transaction infrastructure (PlatformTransactionManager).

Derives from the TransactionAspectSupport class which contains the integration with Spring's underlying transaction API. TransactionInterceptor simply calls the relevant superclass methods such as TransactionAspectSupport.invokeWithinTransaction(java.lang.reflect.Method, java.lang.Class<?>, org.springframework.transaction.interceptor.TransactionAspectSupport.InvocationCallback) in the correct order.

TransactionInterceptors are thread-safe.

Constructor Detail

TransactionInterceptor

public TransactionInterceptor()

Create a new TransactionInterceptor.

Transaction manager and transaction attributes still need to be set.

TransactionAspectSupport.setTransactionManager(org.springframework.transaction.PlatformTransactionManager), TransactionAspectSupport.setTransactionAttributes(java.util.Properties), TransactionAspectSupport.setTransactionAttributeSource(TransactionAttributeSource)

TransactionInterceptor

public TransactionInterceptor(PlatformTransactionManager ptm,
                              java.util.Properties attributes)

Create a new TransactionInterceptor.

Parameters:

ptm - the default transaction manager to perform the actual transaction management

attributes - the transaction attributes in properties format

See Also:

TransactionAspectSupport.setTransactionManager(org.springframework.transaction.PlatformTransactionManager), TransactionAspectSupport.setTransactionAttributes(java.util.Properties)

TransactionInterceptor

public TransactionInterceptor(PlatformTransactionManager ptm,
                              TransactionAttributeSource tas)

Create a new TransactionInterceptor.

Parameters:

ptm - the default transaction manager to perform the actual transaction management

tas - the attribute source to be used to find transaction attributes

Method Detail

invoke

@Nullable
public java.lang.Object invoke(MethodInvocation invocation)
                                  throws java.lang.Throwable

Description copied from interface: MethodInterceptor

Implement this method to perform extra treatments before and after the invocation. Polite implementations would certainly like to invoke Joinpoint.proceed().

Specified by:

invoke in interface MethodInterceptor

Parameters:

invocation - the method invocation joinpoint

Returns:

the result of the call to Joinpoint.proceed(); might be intercepted by the interceptor

Throws:

java.lang.Throwable - if the interceptors or the target object throws an exception
