枚举常量概要

枚举常量

枚举常量	说明
DATABASE	Multi-tenancy implemented as separate databases.
DISCRIMINATOR	Multi-tenancy implemented by use of discriminator columns.
NONE	No multi-tenancy.
SCHEMA	Multi-tenancy implemented as separate schemas.

方法概要

修饰符和类型	方法	说明
static MultiTenancyStrategy	determineMultiTenancyStrategy(Map properties)	Extract the MultiTenancyStrategy from the setting map.
boolean	requiresMultiTenantConnectionProvider()	Does this strategy indicate a requirement for the specialized MultiTenantConnectionProvider, rather than the traditional ConnectionProvider?
static MultiTenancyStrategy	valueOf(String name)	返回带有指定名称的该类型的枚举常量。
static MultiTenancyStrategy[]	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

DISCRIMINATOR

public static final MultiTenancyStrategy DISCRIMINATOR

Multi-tenancy implemented by use of discriminator columns.

SCHEMA

public static final MultiTenancyStrategy SCHEMA

Multi-tenancy implemented as separate schemas.

DATABASE

public static final MultiTenancyStrategy DATABASE

Multi-tenancy implemented as separate databases.

NONE

public static final MultiTenancyStrategy NONE

No multi-tenancy.

方法详细资料

values

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

requiresMultiTenantConnectionProvider

public boolean requiresMultiTenantConnectionProvider()

Does this strategy indicate a requirement for the specialized MultiTenantConnectionProvider, rather than the traditional ConnectionProvider?

返回:

true indicates a MultiTenantConnectionProvider is required; false indicates it is not.

determineMultiTenancyStrategy

public static MultiTenancyStrategy determineMultiTenancyStrategy(Map properties)

Extract the MultiTenancyStrategy from the setting map.

参数:

properties - The map of settings.

返回:

The selected strategy. NONE is always the default.
