方法详细资料

builder

public static ConnectionPoolSettings.Builder builder()

Gets a Builder for creating a new ConnectionPoolSettings instance.

返回:

a new Builder for ConnectionPoolSettings.

getMaxSize

public int getMaxSize()

The maximum number of connections allowed. Those connections will be kept in the pool when idle. Once the pool is exhausted, any operation requiring a connection will block waiting for an available connection.

Default is 100.

返回:

the maximum number of connections in the pool.

getMinSize

public int getMinSize()

The minimum number of connections. Those connections will be kept in the pool when idle, and the pool will ensure that it contains at least this minimum number.

Default is 0.

返回:

the minimum number of connections to have in the pool at all times.

getMaxWaitQueueSize

public int getMaxWaitQueueSize()

This is the maximum number of operations that may be waiting for a connection to become available from the pool. All further operations will get an exception immediately.

Default is 500.

返回:

the number of threads that are allowed to be waiting for a connection.

getMaxWaitTime

public long getMaxWaitTime(java.util.concurrent.TimeUnit timeUnit)

The maximum time that a thread may wait for a connection to become available.

Default is 2 minutes. A value of 0 means that it will not wait. A negative value means it will wait indefinitely.

参数:

timeUnit - the TimeUnit for this wait period

返回:

the maximum amount of time to wait in the given TimeUnits

getMaxConnectionLifeTime

public long getMaxConnectionLifeTime(java.util.concurrent.TimeUnit timeUnit)

The maximum time a pooled connection can live for. A zero value indicates no limit to the life time. A pooled connection that has exceeded its life time will be closed and replaced when necessary by a new connection.

参数:

timeUnit - the TimeUnit to use for this time period

返回:

the maximum length of time a connection can live in the given TimeUnits

getMaxConnectionIdleTime

public long getMaxConnectionIdleTime(java.util.concurrent.TimeUnit timeUnit)

Returns the maximum idle time of a pooled connection. A zero value indicates no limit to the idle time. A pooled connection that has exceeded its idle time will be closed and replaced when necessary by a new connection.

参数:

timeUnit - the TimeUnit to use for this time period

返回:

the maximum time a connection can be unused, in the given TimeUnits

getMaintenanceInitialDelay

public long getMaintenanceInitialDelay(java.util.concurrent.TimeUnit timeUnit)

Returns the period of time to wait before running the first maintenance job on the connection pool.

参数:

timeUnit - the TimeUnit to use for this time period

返回:

the time period to wait in the given units

getMaintenanceFrequency

public long getMaintenanceFrequency(java.util.concurrent.TimeUnit timeUnit)

Returns the time period between runs of the maintenance job.

参数:

timeUnit - the TimeUnit to use for this time period

返回:

the time period between runs of the maintainance job in the given units
