- org.springframework.context.support.ApplicationObjectSupport
- - org.springframework.web.context.support.WebApplicationObjectSupport

所有已实现的接口:
Aware, ApplicationContextAware, ServletContextAware
直接已知子类:
AbstractCachingViewResolver, AbstractHandlerMapping, AbstractView, BeanNameViewResolver, ContentNegotiatingViewResolver, ServerEndpointExporter, WebContentGenerator
```
public abstract class WebApplicationObjectSupport
extends ApplicationObjectSupport
implements ServletContextAware
```
Convenient superclass for application objects running in a WebApplicationContext. Provides getWebApplicationContext(), getServletContext(), and getTempDir() accessors.
Note: It is generally recommended to use individual callback interfaces for the actual callbacks needed. This broad base class is primarily intended for use within the framework, in case of ServletContext access etc typically being needed.

`protected ServletContext`	`getServletContext()`	Return the current ServletContext.

public final void setServletContext(ServletContext servletContext)

    从接口复制的说明: ServletContextAware
    Set the ServletContext that this object runs in.
    Invoked after population of normal bean properties but before an init callback like InitializingBean's afterPropertiesSet or a custom init-method. Invoked after ApplicationContextAware's setApplicationContext.
    指定者:
    setServletContext 在接口中 ServletContextAware
    参数:
    servletContext - ServletContext object to be used by this object
    另请参阅:
    InitializingBean.afterPropertiesSet(), ApplicationContextAware.setApplicationContext(org.springframework.context.ApplicationContext)
  - isContextRequired
```
protected boolean isContextRequired()
```
    Overrides the base class behavior to enforce running in an ApplicationContext. All accessors will throw IllegalStateException if not running in a context.
    覆盖:
    isContextRequired 在类中 ApplicationObjectSupport
    另请参阅:
    ApplicationObjectSupport.getApplicationContext(), ApplicationObjectSupport.getMessageSourceAccessor(), getWebApplicationContext(), getServletContext(), getTempDir()
  - initApplicationContext
```
protected void initApplicationContext(ApplicationContext context)
```
    Calls initServletContext(javax.servlet.ServletContext) if the given ApplicationContext is a WebApplicationContext.
    覆盖:
    initApplicationContext 在类中 ApplicationObjectSupport
    参数:
    context - the containing ApplicationContext
    另请参阅:
    ApplicationObjectSupport.setApplicationContext(org.springframework.context.ApplicationContext)
  - initServletContext
```
protected void initServletContext(ServletContext servletContext)
```
    Subclasses may override this for custom initialization based on the ServletContext that this application object runs in.
    The default implementation is empty. Called by initApplicationContext(org.springframework.context.ApplicationContext) as well as setServletContext(javax.servlet.ServletContext).
    参数:
    servletContext - the ServletContext that this application object runs in (never null)
  - getWebApplicationContext
```
protected final WebApplicationContext getWebApplicationContext()
                                                        throws IllegalStateException
```
    Return the current application context as WebApplicationContext.
    NOTE: Only use this if you actually need to access WebApplicationContext-specific functionality. Preferably use getApplicationContext() or getServletContext() else, to be able to run in non-WebApplicationContext environments as well.
    抛出:
    IllegalStateException - if not running in a WebApplicationContext
    另请参阅:
    ApplicationObjectSupport.getApplicationContext()
  - getServletContext
```
protected final ServletContext getServletContext()
                                          throws IllegalStateException
```
    Return the current ServletContext.
    抛出:
    IllegalStateException - if not running within a ServletContext
  - getTempDir
```
protected final File getTempDir()
                         throws IllegalStateException
```
    Return the temporary directory for the current web application, as provided by the servlet container.
    返回:
    the File representing the temporary directory
    抛出:
    IllegalStateException - if not running within a ServletContext

    WebUtils.getTempDir(javax.servlet.ServletContext)
