Class Overview

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

Contributes ServletConfig- and ServletContext-based PropertySource instances. See the DefaultWebEnvironment() constructor for details.

After initial bootstrapping, property sources will be searched for the presence of a "jndiPropertySourceEnabled" property; if found, a JndiPropertySource will be added to this environment's PropertySources, with precedence higher than system properties and environment variables, but lower than that of ServletContext and ServletConfig init params.

Create a new Environment populated with the property sources contributed by superclasses as well as:
  • {@value #SERVLET_CONFIG_PROPERTY_SOURCE_NAME}
  • {@value #SERVLET_CONTEXT_PROPERTY_SOURCE_NAME}
  • (optionally) "jndiPropertySource"

Properties present in {@value #SERVLET_CONFIG_PROPERTY_SOURCE_NAME} will take precedence over those in {@value #SERVLET_CONTEXT_PROPERTY_SOURCE_NAME}.

Constants

public static final String SERVLET_CONFIG_PROPERTY_SOURCE_NAME

Servlet context init parameters property source name: {@value }

Constant Value: "servletContextInitParams"

Public Constructors

public DefaultWebEnvironment ()

Create a new Environment populated with the property sources contributed by superclasses as well as:

  • {@value #SERVLET_CONFIG_PROPERTY_SOURCE_NAME}
  • {@value #SERVLET_CONTEXT_PROPERTY_SOURCE_NAME}
  • (optionally) "jndiPropertySource"

Properties present in {@value #SERVLET_CONFIG_PROPERTY_SOURCE_NAME} will take precedence over those in {@value #SERVLET_CONTEXT_PROPERTY_SOURCE_NAME}. Properties in either will take precedence over system properties and environment variables.

The Servlet-related property sources are added as stubs for now, and will be fully initialized once the actual ServletConfig and ServletContext objects are available.

If the "jndiPropertySourceEnabled" property is present in any of the default property sources, a JndiPropertySource will be added as well, with precedence lower than servlet property sources, but higher than system properties and environment variables.
