- org.springframework.transaction.support.ResourceHolderSupport

所有已实现的接口:
ResourceHolder
直接已知子类:
ConnectionHolder, ConnectionHolder, EntityManagerHolder, JmsResourceHolder
```
public abstract class ResourceHolderSupport
extends Object
implements ResourceHolder
```
Convenient base class for resource holders.
Features rollback-only support for participating transactions. Can expire after a certain number of seconds or milliseconds in order to determine a transactional timeout.

方法概要

所有方法实例方法具体方法
修饰符和类型	方法	说明
`void`	`clear()`	Clear the transactional state of this resource holder.
`Date`	`getDeadline()`	Return the expiration deadline of this object.
`long`	`getTimeToLiveInMillis()`	Return the time to live for this object in milliseconds.
`int`	`getTimeToLiveInSeconds()`	Return the time to live for this object in seconds.
`boolean`	`hasTimeout()`	Return whether this object has an associated timeout.
`boolean`	`isOpen()`	Return whether there are still open references to this holder.
`boolean`	`isRollbackOnly()`	Return whether the resource transaction is marked as rollback-only.
`boolean`	`isSynchronizedWithTransaction()`	Return whether the resource is synchronized with a transaction.
`boolean`	`isVoid()`	Determine whether this holder is considered as 'void', i.e. as a leftover from a previous thread.
`void`	`released()`	Decrease the reference count by one because the holder has been released (i.e. someone released the resource held by it).
`void`	`requested()`	Increase the reference count by one because the holder has been requested (i.e. someone requested the resource held by it).
`void`	`reset()`	Reset this resource holder - transactional state as well as reference count.
`void`	`resetRollbackOnly()`	Reset the rollback-only status for this resource transaction.
`void`	`setRollbackOnly()`	Mark the resource transaction as rollback-only.
`void`	`setSynchronizedWithTransaction(boolean synchronizedWithTransaction)`	Mark the resource as synchronized with a transaction.
`void`	`setTimeoutInMillis(long millis)`	Set the timeout for this object in milliseconds.
`void`	`setTimeoutInSeconds(int seconds)`	Set the timeout for this object in seconds.
`void`	`unbound()`	Notify this holder that it has been unbound from transaction synchronization.

  - ResourceHolderSupport
```
public ResourceHolderSupport()
```
- 方法详细资料
  - setSynchronizedWithTransaction
```
public void setSynchronizedWithTransaction(boolean synchronizedWithTransaction)
```
    Mark the resource as synchronized with a transaction.
  - isSynchronizedWithTransaction
```
public boolean isSynchronizedWithTransaction()
```
    Return whether the resource is synchronized with a transaction.
  - setRollbackOnly
```
public void setRollbackOnly()
```
    Mark the resource transaction as rollback-only.
  - resetRollbackOnly
```
public void resetRollbackOnly()
```
    Reset the rollback-only status for this resource transaction.
    Only really intended to be called after custom rollback steps which keep the original resource in action, e.g. in case of a savepoint.

  - isRollbackOnly
```
public boolean isRollbackOnly()
```
    Return whether the resource transaction is marked as rollback-only.
  - setTimeoutInSeconds
```
public void setTimeoutInSeconds(int seconds)
```
    Set the timeout for this object in seconds.
    参数:
    seconds - number of seconds until expiration
  - setTimeoutInMillis
```
public void setTimeoutInMillis(long millis)
```
    Set the timeout for this object in milliseconds.
    参数:
    millis - number of milliseconds until expiration

```
public boolean hasTimeout()
```
    Return whether this object has an associated timeout.
  - getDeadline
```
@Nullable
public Date getDeadline()
```
    Return the expiration deadline of this object.
    返回:
    the deadline as Date object
  - getTimeToLiveInSeconds
```
public int getTimeToLiveInSeconds()
```
    Return the time to live for this object in seconds. Rounds up eagerly, e.g. 9.00001 still to 10.
    返回:
    number of seconds until expiration
    抛出:
    TransactionTimedOutException - if the deadline has already been reached
  - getTimeToLiveInMillis
```
public long getTimeToLiveInMillis()
                           throws TransactionTimedOutException
```
    Return the time to live for this object in milliseconds.
    返回:
    number of milliseconds until expiration
    抛出:
    TransactionTimedOutException - if the deadline has already been reached
  - requested
```
public void requested()
```
    Increase the reference count by one because the holder has been requested (i.e. someone requested the resource held by it).
  - released
```
public void released()
```
    Decrease the reference count by one because the holder has been released (i.e. someone released the resource held by it).
  - isOpen
```
public boolean isOpen()
```
    Return whether there are still open references to this holder.
  - clear
```
public void clear()
```
    Clear the transactional state of this resource holder.
  - reset
```
public void reset()
```
    Reset this resource holder - transactional state as well as reference count.
    指定者:
    reset 在接口中 ResourceHolder
  - unbound
```
public void unbound()
```
    从接口复制的说明: ResourceHolder
    Notify this holder that it has been unbound from transaction synchronization.
    指定者:
    unbound 在接口中 ResourceHolder
  - isVoid
```
public boolean isVoid()
```
    从接口复制的说明: ResourceHolder
    Determine whether this holder is considered as 'void', i.e. as a leftover from a previous thread.
    指定者:
