TransactionalOperatorImplback to summary
pack-priv TransactionalOperatorImpl(ReactiveTransactionManager transactionManager, TransactionDefinition transactionDefinition)

Construct a new TransactionTemplate using the given transaction manager, taking its default settings from the given transaction definition.

Parameters
transactionManager:ReactiveTransactionManager

the transaction management strategy to be used

transactionDefinition:TransactionDefinition

the transaction definition to copy the default settings from. Local properties can still be set to change values.

Method Detail

equalsback to summary
public boolean equals(Object other)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

executeback to summary
public <T> Flux<T> execute(TransactionCallback<T> action) throws TransactionException

Implements org.springframework.transaction.reactive.TransactionalOperator.execute.

Doc from org.springframework.transaction.reactive.TransactionalOperator.execute.

Execute the action specified by the given callback object within a transaction.

Allows for returning a result object created within the transaction, that is, a domain object or a collection of domain objects. A RuntimeException thrown by the callback is treated as a fatal exception that enforces a rollback. Such an exception gets propagated to the caller of the template.

Parameters
action:TransactionCallback<T>

the callback object that specifies the transactional action

Returns:Flux<T>

a result object returned by the callback

Annotations

Exceptions
TransactionException:
in case of initialization, rollback, or system errors
getTransactionManagerback to summary
public ReactiveTransactionManager getTransactionManager()

Return the transaction management strategy to be used.

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

Annotations
@Override
rollbackOnExceptionback to summary
private Mono<Void> rollbackOnException(ReactiveTransaction status, Throwable ex) throws TransactionException

Perform a rollback, handling rollback exceptions properly.

Parameters
status:ReactiveTransaction

object representing the transaction

ex:Throwable

the thrown application exception or error

Exceptions
TransactionException:
in case of a rollback error
unwrapIfResourceCleanupFailureback to summary
private Throwable unwrapIfResourceCleanupFailure(Throwable ex)

Unwrap the cause of a throwable, if produced by a failure during the async resource cleanup in Flux#usingWhen.

Parameters
ex:Throwable

the throwable to try to unwrap
