Class StandardServletEnvironment

java.lang.Object

org.springframework.core.env.AbstractEnvironment

org.springframework.core.env.StandardEnvironment

org.springframework.web.context.support.StandardServletEnvironment

All Implemented Interfaces:

ConfigurableEnvironment, ConfigurablePropertyResolver, Environment, PropertyResolver, ConfigurableWebEnvironment

public class StandardServletEnvironment
extends StandardEnvironment
implements ConfigurableWebEnvironment

Environment implementation to be used by Servlet-based web applications. All web-related (servlet-based) ApplicationContext classes initialize an instance by default.

Contributes ServletConfig, ServletContext, and JNDI-based PropertySource instances. See customizePropertySources(org.springframework.core.env.MutablePropertySources) method documentation for details.

Constructor Details

StandardServletEnvironment

public StandardServletEnvironment()

Create a new StandardServletEnvironment instance.

StandardServletEnvironment

protected StandardServletEnvironment(MutablePropertySources propertySources)

Create a new StandardServletEnvironment instance with a specific MutablePropertySources instance.

Parameters:

propertySources - property sources to use

Since:

5.3.4

Method Details

customizePropertySources

protected void customizePropertySources(MutablePropertySources propertySources)

Customize the set of property sources with those contributed by superclasses as well as those appropriate for standard servlet-based environments:

• "servletConfigInitParams"
• "servletContextInitParams"
• "jndiProperties"

Properties present in "servletConfigInitParams" will take precedence over those in "servletContextInitParams", and properties found in either of the above take precedence over those found in "jndiProperties".

Properties in any of the above will take precedence over system properties and environment variables contributed by the StandardEnvironment superclass.

The Servlet-related property sources are added as stubs at this stage, and will be fully initialized once the actual ServletContext object becomes available.

Addition of "jndiProperties" can be disabled with JndiLocatorDelegate.IGNORE_JNDI_PROPERTY_NAME.

Overrides:

customizePropertySources in class StandardEnvironment

initPropertySources

public void initPropertySources(@Nullable
 ServletContext servletContext,
 @Nullable
 ServletConfig servletConfig)

Description copied from interface: ConfigurableWebEnvironment

Specified by:

initPropertySources in interface ConfigurableWebEnvironment

Parameters:

servletContext - the ServletContext (may not be null)

servletConfig - the ServletConfig (null if not available)
