```
public class TransactionTemplate
extends DefaultTransactionDefinition
implements TransactionOperations, InitializingBean
```
Template class that simplifies programmatic transaction demarcation and transaction exception handling.
The central method is execute(org.springframework.transaction.support.TransactionCallback<T>), supporting transactional code that implements the TransactionCallback interface. This template handles the transaction lifecycle and possible exceptions such that neither the TransactionCallback implementation nor the calling code needs to explicitly handle transactions.
Typical usage: Allows for writing low-level data access objects that use resources such as JDBC DataSources but are not transaction-aware themselves. Instead, they can implicitly participate in transactions handled by higher-level application services utilizing this class, making calls to the low-level services via an inner-class callback object.
Can be used within a service implementation via direct instantiation with a transaction manager reference, or get prepared in an application context and passed to services as bean reference. Note: The transaction manager should always be configured as bean in the application context: in the first case given to the service directly, in the second case given to the prepared template.
Supports setting the propagation behavior and the isolation level by name, for convenient configuration in context definitions.

```
public TransactionTemplate()
```
    Construct a new TransactionTemplate for bean usage.
    Note: The PlatformTransactionManager needs to be set before any execute calls.
    另请参阅:
    setTransactionManager(org.springframework.transaction.PlatformTransactionManager)
  - TransactionTemplate
```
public TransactionTemplate(PlatformTransactionManager transactionManager)
```
    Construct a new TransactionTemplate using the given transaction manager.
    参数:
    transactionManager - the transaction management strategy to be used
  - TransactionTemplate
```
public TransactionTemplate(PlatformTransactionManager transactionManager,
                           TransactionDefinition transactionDefinition)
```
    Construct a new TransactionTemplate using the given transaction manager, taking its default settings from the given transaction definition.
    参数:
    transactionManager - the transaction management strategy to be used
    transactionDefinition - the transaction definition to copy the default settings from. Local properties can still be set to change values.

public void setTransactionManager(PlatformTransactionManager transactionManager)

    从接口复制的说明: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    指定者:
    afterPropertiesSet 在接口中 InitializingBean
  - execute
```
public <T> T execute(TransactionCallback<T> action)
              throws TransactionException
```
    从接口复制的说明: TransactionOperations
    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.
    指定者:
    execute 在接口中 TransactionOperations
    参数:
    action - the callback object that specifies the transactional action
    返回:
    a result object returned by the callback, or null if none
    抛出:
    TransactionException - in case of initialization, rollback, or system errors
  - equals
```
public boolean equals(Object other)
```
    从类复制的说明: DefaultTransactionDefinition
    This implementation compares the toString() results.
    覆盖:
    equals 在类中 DefaultTransactionDefinition
    另请参阅:
    DefaultTransactionDefinition.toString()
