ServletContextInitializer (Spring Boot API)

所有已知实现类:
AbstractFilterRegistrationBean, DelegatingFilterProxyRegistrationBean, DynamicRegistrationBean, FilterRegistrationBean, RegistrationBean, ServletListenerRegistrationBean, ServletRegistrationBean
函数接口:
这是一个函数接口, 因此可用作 lambda 表达式或方法引用的赋值目标。
```
@FunctionalInterface
public interface ServletContextInitializer
```
Interface used to configure a Servlet 3.0+ context programmatically. Unlike WebApplicationInitializer, classes that implement this interface (and do not implement WebApplicationInitializer) will not be detected by SpringServletContainerInitializer and hence will not be automatically bootstrapped by the Servlet container.
This interface is primarily designed to allow ServletContextInitializers to be managed by Spring and not the Servlet container.
For configuration examples see WebApplicationInitializer.
从以下版本开始:
1.4.0
