`boolean`	`getRequireFullStackTrace()` Indicates if full stack traces are required when `logAbandoned` is true.

public AbandonedConfig()
```
- 方法详细资料
  - getLogAbandoned
```
public boolean getLogAbandoned()
```
    Flag to log stack traces for application code which abandoned an object. Defaults to false. Logging of abandoned objects adds overhead for every object created because a stack trace has to be generated.
    
    返回:
    
    boolean true if stack trace logging is turned on for abandoned objects
  - getLogWriter
```
public java.io.PrintWriter getLogWriter()
```
    Gets the log writer being used by this configuration to log information on abandoned objects. If not set, a PrintWriter based on System.out with the system default encoding is used.
    
    返回:
    
    log writer in use
  - getRemoveAbandonedOnBorrow
```
public boolean getRemoveAbandonedOnBorrow()
```
    Flag to remove abandoned objects if they exceed the removeAbandonedTimeout when borrowObject is invoked.
    
    The default value is false.
    
    If set to true, abandoned objects are removed by borrowObject if there are fewer than 2 idle objects available in the pool and getNumActive() > getMaxTotal() - 3
    
    返回:
    
    true if abandoned objects are to be removed by borrowObject
  - getRemoveAbandonedOnMaintenance
```
public boolean getRemoveAbandonedOnMaintenance()
```
    Flag to remove abandoned objects if they exceed the removeAbandonedTimeout when pool maintenance (the "evictor") runs.
    
    The default value is false.
    
    If set to true, abandoned objects are removed by the pool maintenance thread when it runs. This setting has no effect unless maintenance is enabled by setting timeBetweenEvictionRuns to a positive number.
    
    返回:
    
    true if abandoned objects are to be removed by the evictor
  - getRemoveAbandonedTimeout
```
@Deprecated
public int getRemoveAbandonedTimeout()
```
    已过时。 Use getRemoveAbandonedTimeoutDuration().
    
    Timeout in seconds before an abandoned object can be removed.
    
    The time of most recent use of an object is the maximum (latest) of TrackedUse.getLastUsed() (if this class of the object implements TrackedUse) and the time when the object was borrowed from the pool.
    
    The default value is 300 seconds.
    
    返回:
    
    the abandoned object timeout in seconds
  - getRemoveAbandonedTimeoutDuration
```
public java.time.Duration getRemoveAbandonedTimeoutDuration()
```
    Timeout before an abandoned object can be removed.
    
    The time of most recent use of an object is the maximum (latest) of TrackedUse.getLastUsed() (if this class of the object implements TrackedUse) and the time when the object was borrowed from the pool.
    
    The default value is 300 seconds.
    
    返回:
    
    the abandoned object timeout.
    
    从以下版本开始:
    
    2.10.0
  - getRequireFullStackTrace
```
public boolean getRequireFullStackTrace()
```
    Indicates if full stack traces are required when logAbandoned is true. Defaults to true. Logging of abandoned objects requiring a full stack trace will generate an entire stack trace to generate for every object created. If this is disabled, a faster but less informative stack walking mechanism may be used if available.
    
    返回:
    
    true if full stack traces are required for logging abandoned connections, or false if abbreviated stack traces are acceptable
    
    从以下版本开始:
    
    2.5

  - getUseUsageTracking
```
public boolean getUseUsageTracking()
```
    If the pool implements UsageTracking, should the pool record a stack trace every time a method is called on a pooled object and retain the most recent stack trace to aid debugging of abandoned objects?
    
    返回:
    
    true if usage tracking is enabled
  - setLogAbandoned

public void setLogAbandoned(boolean logAbandoned)

    getRemoveAbandonedOnMaintenance()
  - setRemoveAbandonedTimeout
```
public void setRemoveAbandonedTimeout(java.time.Duration removeAbandonedTimeout)

@Deprecated
public void setRemoveAbandonedTimeout(int removeAbandonedTimeout)

    已过时。 Use setRemoveAbandonedTimeout(Duration).
    
    Sets the timeout in seconds before an abandoned object can be removed
