StandardServletEnvironment (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.core.env.AbstractEnvironment
- - org.springframework.core.env.StandardEnvironment
  - - org.springframework.web.context.support.StandardServletEnvironment

所有已实现的接口:
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.
从以下版本开始:

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.
