정상입니까? 내가 브라우저에서 서블릿을 요청하면이를 확인하려면 나는

http://localhost:4502/apps/path/to/my/servlet 

나는 다음과 같은 오류를 받고 있어요, 간단한 servelet

import java.io.IOException; 
import javax.servlet.ServletException; 
import org.apache.sling.api.SlingHttpServletRequest; 
import org.apache.sling.api.SlingHttpServletResponse; 
import org.apache.sling.api.servlets.SlingSafeMethodsServlet; 
import org.slf4j.Logger; 
org.slf4j.LoggerFactory; 

@Component(immediate = true, metatype = false) 
@Service(value = javax.servlet.Servlet.class) 
@Properties(value = { @Property(name = "sling.servlet.methods", value = { "GET" }), 
     @Property(name = "sling.servlet.paths", value = { "/path/to/my/servlet", "/apps/path/to/my/servlet" }) })

Answer 1

마지막으로 이유를 찾을 수 있습니다. 이는에 serviceComponents.xml 내 번들에서 누락 된 인해

나는 내 pom.xml 파일에서 maven-scr-plugin를 놓쳤다. ( My previous thread를 참조하십시오)
