ServletContextAttributeExporter (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- org.springframework.web.context.support.ServletContextAttributeExporter

所有已实现的接口:
Aware, ServletContextAware
```
public class ServletContextAttributeExporter
extends Object
implements ServletContextAware
```
Exporter that takes Spring-defined objects and exposes them as ServletContext attributes. Usually, bean references will be used to export Spring-defined beans as ServletContext attributes.
Useful to make Spring-defined beans available to code that is not aware of Spring at all, but rather just of the Servlet API. Client code can then use plain ServletContext attribute lookups to access those objects, despite them being defined in a Spring application context.
Alternatively, consider using the WebApplicationContextUtils class to access Spring-defined beans via the WebApplicationContext interface. This makes client code aware of Spring API, of course.

    Set the ServletContext attributes to expose as key-value pairs. Each key will be considered a ServletContext attributes key, and each value will be used as corresponding attribute value.
    Usually, you will use bean references for the values, to export Spring-defined beans as ServletContext attributes. Of course, it is also possible to define plain values to export.
  - setServletContext
```
public 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)
