Single TransactionTemplate to perform variations of transaction configurations [SPR-17491]

[spring-projects-issues]

Tadaya Tsuyukubo opened SPR-17491 and commented

With TransactionTemplate, for example, setReadOnly(true) is called, all executions with this template becomes readOnly transactions. If I want to perform another transaction with non-readonly, I need to create another template and so for all variation of transactions.

Instead, It would be nice to perform various transaction configurations with single TransactionTemplate.

 

For example:

 

public <T> T execute(Consumer<DefaultTransactionDefinition> txConfig, TransactionCallback<T> action) throws TransactionException 

 

 

template.execute( txConfig -> {
   txConfig.setReadOnly(true);
   txConfig.setIsolationLevel(...);
   ...
 }, status -> {
   // action to perform in transaction
});

Thinking a bit more, TransactionTemplate may not be a good place to add since it is a stateful for transaction definitions.

 

So, maybe something like:

public class SimpleTransactionTemplate {
   // with default
   public <T> T execute(TransactionCallback<T> action) throws TransactionException {
     ...
   }
   public <T> T execute(TransactionDefinition definition, TransactionCallback<T> action) throws TransactionException {
     ...
   }
}

 

 

If API looks ok, then I can write a PR for this.
