枚举 ConnectionAcquisitionMode

java.lang.Object

java.lang.Enum<ConnectionAcquisitionMode>

org.hibernate.ConnectionAcquisitionMode

所有已实现的接口:

Serializable, Comparable<ConnectionAcquisitionMode>

public enum ConnectionAcquisitionMode
extends Enum<ConnectionAcquisitionMode>

Indicates the manner in which JDBC Connections should be acquired. Inverse to ConnectionReleaseMode.

枚举常量详细资料

IMMEDIATELY

public static final ConnectionAcquisitionMode IMMEDIATELY

The Connection will be acquired as soon as the Hibernate Session is opened. This also circumvents ConnectionReleaseMode, as the Connection will then be held until the Session is closed.

AS_NEEDED

public static final ConnectionAcquisitionMode AS_NEEDED

The legacy behavior. A Connection is only acquired when (if) it is actually needed.

方法详细资料

values

public static ConnectionAcquisitionMode[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (ConnectionAcquisitionMode c : ConnectionAcquisitionMode.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static ConnectionAcquisitionMode valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
