枚举 ConnectionReleaseMode

java.lang.Object

java.lang.Enum<ConnectionReleaseMode>

org.hibernate.ConnectionReleaseMode

所有已实现的接口:

Serializable, Comparable<ConnectionReleaseMode>

public enum ConnectionReleaseMode
extends Enum<ConnectionReleaseMode>

Defines the various policies by which Hibernate might release its underlying JDBC connection. Inverse of ConnectionAcquisitionMode.

枚举常量概要

枚举常量

枚举常量	说明
AFTER_STATEMENT	Indicates that JDBC connection should be aggressively released after each SQL statement is executed.
AFTER_TRANSACTION	Indicates that JDBC connections should be released after each transaction ends (works with both JTA-registered synch and HibernateTransaction API).
ON_CLOSE	Indicates that connections should only be released when the Session is explicitly closed or disconnected; this is the legacy (Hibernate2 and pre-3.1) behavior.

方法概要

修饰符和类型	方法	说明
static ConnectionReleaseMode	interpret(Object setting)
static ConnectionReleaseMode	parse(String name)	Alias for valueOf(String) using upper-case version of the incoming name.
static ConnectionReleaseMode	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static ConnectionReleaseMode[]	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。

枚举常量详细资料

AFTER_STATEMENT

public static final ConnectionReleaseMode AFTER_STATEMENT

Indicates that JDBC connection should be aggressively released after each SQL statement is executed. In this mode, the application must explicitly close all iterators and scrollable results. This mode may only be used with a JTA datasource.

AFTER_TRANSACTION

public static final ConnectionReleaseMode AFTER_TRANSACTION

Indicates that JDBC connections should be released after each transaction ends (works with both JTA-registered synch and HibernateTransaction API). This mode may not be used with an application server JTA datasource.

This is the default mode starting in 3.1; was previously ON_CLOSE.

ON_CLOSE

public static final ConnectionReleaseMode ON_CLOSE

Indicates that connections should only be released when the Session is explicitly closed or disconnected; this is the legacy (Hibernate2 and pre-3.1) behavior.

方法详细资料

values

public static ConnectionReleaseMode[] 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 (ConnectionReleaseMode c : ConnectionReleaseMode.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 ConnectionReleaseMode 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

parse

public static ConnectionReleaseMode parse(String name)

Alias for valueOf(String) using upper-case version of the incoming name.

参数:

name - The name to parse

返回:

The matched enum value.

interpret

public static ConnectionReleaseMode interpret(Object setting)
