bahar WebApplicationInitializer StandardContext yayınının, ciddi bir şekilde başlatıldıktan hemen sonra yeniden yüklenmesini nasıl sağlar?

Question

Aşağıdaki kodla birlikte AbstractAnnotationConfigDispatcherServletInitializer yerine ilkbahar WebApplicationInitializer kullanıyorum.

Uygulama ilk başlatma tamamlandıktan sonra yeniden yüklenir ve aşağıdaki günlüğe yeniden başlar.

i kullanırsanız AbstractAnnotationConfigDispatcherServletInitializer

public class SpringWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { 

@Override 
protected Class<?>[] getRootConfigClasses() { 
    return new Class<?>[] { AppConfig.class }; 
    // return new Class[] { WebMvcConfig.class }; 
    // return null; 
} 

// Since we have a single DispatcherServlet here, we can add the WebConfig 
// to the root context and make the servlet context empty 
@Override 
protected Class<?>[] getServletConfigClasses() { 
    return new Class<?>[] { WebMvcConfig.class }; 
    // return new Class[] { }; 
    // return null; 
} 

@Override 
protected String[] getServletMappings() { 

    return new String[] { "/" }; 
} 

@Override 
protected Filter[] getServletFilters() { 
    return new Filter[] { new DelegatingFilterProxy("springSecurityFilterChain"), 
      new OpenEntityManagerInViewFilter() }; 
} 

// By default when the DispatcherServlet can't find a handler for a request 
// it sends a 404 response. However if its property 
// "throwExceptionIfNoHandlerFound" is set to true this exception is raised 
// and may be handled with a configured HandlerExceptionResolver 
@Override 
protected void customizeRegistration(ServletRegistration.Dynamic registration) { 
    boolean done = registration.setInitParameter("throwExceptionIfNoHandlerFound", "true"); // -> 
                          // true 
    if (!done) 
     throw new RuntimeException(); 
} 

} 

sunucu yalnızca bir defa

sorunu nedir başarıyı başlamak yolunda mı?

Answer 1

Bunu iki kere yeniden yükler, bu yüzden iki kez başlatmasını gibidir:

// Register the Root application context 
    AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext(); 
. 
. 
. 
    // Register the Web application context 
    AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext(); 
    mvcContext.register(WebMvcConfig.class);
