DEFAULT

static final ApplicationContextFactory DEFAULT

A default ApplicationContextFactory implementation that will create an appropriate context for the WebApplicationType.

方法详细资料

getEnvironmentType

default Class<? extends ConfigurableEnvironment> getEnvironmentType(WebApplicationType webApplicationType)

Return the Environment type expected to be set on the created application context. The result of this method can be used to convert an existing environment instance to the correct type.

参数:

webApplicationType - the web application type

返回:

the expected application context type or null to use the default

从以下版本开始:

2.6.14

createEnvironment

default ConfigurableEnvironment createEnvironment(WebApplicationType webApplicationType)

Create a new Environment to be set on the created application context. The result of this method must match the type returned by getEnvironmentType(WebApplicationType).

参数:

webApplicationType - the web application type

返回:

an environment instance or null to use the default

从以下版本开始:

2.6.14

create

ConfigurableApplicationContext create(WebApplicationType webApplicationType)

Creates the application context for a SpringApplication, respecting the given webApplicationType.

参数:

webApplicationType - the web application type

返回:

the newly created application context

ofContextClass

static ApplicationContextFactory ofContextClass(Class<? extends ConfigurableApplicationContext> contextClass)

Creates an ApplicationContextFactory that will create contexts by instantiating the given contextClass through its primary constructor.

参数:

contextClass - the context class

返回:

the factory that will instantiate the context class

另请参阅:

• BeanUtils.instantiateClass(Class)

of

static ApplicationContextFactory of(Supplier<ConfigurableApplicationContext> supplier)

Creates an ApplicationContextFactory that will create contexts by calling the given Supplier.

参数:

supplier - the context supplier, for example AnnotationConfigApplicationContext::new

返回:

the factory that will instantiate the context class
