Method Detail

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 ServletConfig and ServletContext objects become available.

Overrides:
