Answer 1

@Bean public SimpleUrlHandlerMapping simpleURLHandlerMapping() {
SimpleUrlHandlerMapping mapping = new SimpleUrlHandlerMapping();
mapping.setOrder(Integer.MAX_VALUE - 2);

Properties urlProperties = new Properties();
urlProperties.put("/welcome.htm", "welcomeController");

mapping.setMappings(urlProperties);
mapping.setInterceptors(new Object[]{ maintenanceInterceptor(), executeTimeInterceptor() });

return mapping; }

Answer 2

Autowire your interceptors in your class before you use it.

@Autowired
private MaintenanceInterceptor maintenanceInterceptor;

@Autowired
private ExecuteTimeInterceptor executeTimeInterceptor;

@Bean
public SimpleUrlHandlerMapping simpleUrlHandlerMapping(){
    SimpleUrlHandlerMapping simpleUrlHandlerMapping = new SimpleUrlHandlerMapping();

    //Add your mappings
    Properties mappings = new Properties();
    mappings.setProperty("/welcome.htm", "welcome.htm");
    simpleUrlHandlerMapping.setMappings(mappings);

    //Add your interceptors
    List<HandlerInterceptorAdapter> interceptors = new ArrayList<>();
    interceptors.add(maintenanceInterceptor);
    interceptors.add(executeTimeInterceptor);
    simpleUrlHandlerMapping.setInterceptors(interceptors.toArray());

    return simpleUrlHandlerMapping;
}
