public class ManyToManyAssembleOperationHandler
extends AbstractAssembleOperationHandler

An implementation of AssembleOperationHandler for the one-to-one mapping between the target object and the data source object.

The difference between ManyToManyAssembleOperationHandler and OneToManyAssembleOperationHandler is that OneToManyAssembleOperationHandler is used to handle the situation where multiple values can be obtained through a key in the data source container, while ManyToManyAssembleOperationHandler is used to handle the situation where only one value can be obtained through a key, but there are multiple keys at the same time.

Get the data source object associated with the target object.

覆盖:

getTheAssociatedSource 在类中 AbstractAssembleOperationHandler

参数:

target - target

sources - sources

返回:

data source object associated with the target object

completeMapping

protected void completeMapping(Object source,
                               AbstractAssembleOperationHandler.Target target)

Complete attribute mapping between the target object and the data source object.

指定者:

completeMapping 在类中 AbstractAssembleOperationHandler

参数:

source - source

target - target

determineKeyResolver

public KeyResolver determineKeyResolver(AssembleOperation operation)

Determine key resolver for the operation.

参数:

operation - operation
