SpringWebAppInitializer.java :

import javax.servlet.ServletContext; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRegistration; 

import org.springframework.web.WebApplicationInitializer; 
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext; 
import org.springframework.web.servlet.DispatcherServlet; 

public class SpringWebAppInitializer implements WebApplicationInitializer { 

    @Override 
    public void onStartup(ServletContext servletContext) throws ServletException { 
     AnnotationConfigWebApplicationContext appContext = new AnnotationConfigWebApplicationContext(); 
     appContext.register(ApplicationContextConfig.class); 

     ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher", new DispatcherServlet(appContext)); 
     dispatcher.setLoadOnStartup(1); 
     dispatcher.addMapping("/"); 
    } 

} 

어떤 생각을 왜 방법 addServlet이 ServletContext 인 경우유형의 두 번째 인수에는 적용 할 수 없습니다.?

---

그래서 방법은 addServlet에만 두 번째 매개 변수로 Servlet 클래스를 받아? 아래 코드에서

Answer 1

: 당신이 appContext를 사용하는

ServletRegistration.Dynamic dispatcher = servletContext.addServlet("SpringDispatcher", new DispatcherServlet(appContext)); 

.

DispatcherServlet의 Spring 응용 프로그램 컨텍스트를 만든 다음 그 값을 제공하십시오.

예 : 아래 코드를 추가하십시오 :

// Create the dispatcher servlet's Spring application context 
     AnnotationConfigWebApplicationContext dispatcherContext = 
     new AnnotationConfigWebApplicationContext(); 
     dispatcherContext.register(DispatcherConfig.class); 

     // Register and map the dispatcher servlet 
     ServletRegistration.Dynamic dispatcher = 
     servletContext.addServlet("dispatcher", new DispatcherServlet(dispatcherContext)); 

이것은 작동합니다.
