how to set header no cache in spring mvc 3 by annotation

by

There is no such option. You can use an interceptor: <mvc:annotation-driven/> <mvc:interceptors> <bean id=”webContentInterceptor” class=”org.springframework.web.servlet.mvc.WebContentInterceptor”> <property name=”cacheSeconds” value=”0″/> <property name=”useExpiresHeader” value=”true”/> <property name=”useCacheControlHeader” value=”true”/> <property name=”useCacheControlNoStore” value=”true”/> </bean> </mvc:interceptors> (taken from here) On one hand it is logical not to have such annotation. Annotations on spring-mvc methods are primarily to let the container decide which … Read more

In order to get the latter, though, you have a few methods available on HttpServletRequest: You can either call getScheme(), getServerName(), getServerPort() and getContextPath() and combine … Read more

Are @ManagedBeans obsolete in JavaEE6 because of @Named in CDI/Weld?

by

In short, @ManagedBean makes sense for applications that use JSF but do not use JSR 299 (whatever the reason is). Below a longer explanation from Gavin King: Re: Comparisons to @ManagedBean annotations in JSF2?: While looking through the Weld examples, and the older WebBeans documentation, it looks like a competitor to the new @ManagedBean JSF … Read more

JSF Controller, Service and DAO

by

Is this the correct way of doing things? Apart from performing business logic the inefficient way in a managed bean getter method, and using a too broad managed bean scope, it looks okay. If you move the service call from the getter method to a @PostConstruct method and use either @RequestScoped or @ViewScoped instead of … Read more

by

What does the @EJBs annotation do?

by

The @EJB annotation (and @Resource, @WebServiceRef, etc.) serves two purposes: It declares a reference in the component namespace. For example, @EJB(name=”myEJB”) creates a reference java:comp/env/myEJB. If you annotate a field and do not specify a name, then it creates a reference java:comp/env/com.example.MyClass/myField. If the annotation is declared on a field or setter method, then the … Read more
