java - How to instrument / advice a Spring Data (JPA) repository? -

-

I failed in trying to advise Spring Data JPP repository. The goal is to target all non- zero public methods in a particular repository annotated with target custom annotations (ResourceNotFound in this example) and when a return value is either null. City, Long & gt;, JpaSpecificationExecutor & lt; City & gt or an empty archive 

  @Repository @ResourceNotFound @Transactional (read only = true) Public Interface CityRepository JpaRepository & lt Expand {  
  @ResourceNotFound . Public void beanAnnotatedWithResourceNotFound () {} @Pointcut ("execution (public * * (..))" public ("zero" (com.digitalmisfits.spring.aop.annotation.ResourceNotFound * ) "@Pointcut Public Law () {@ @ (" Bean Untotted With Resource Notfoud () & amp; Public Law () ") Public Object PublicMethodInsideAClass Marked Wise Resource Notfound (ProceedingJoinpointPJP) Throwshell { System.out.println ("publicMethodInsideAClassMarkedWithResourceNotFound" + pjp.getTarget (). ToString ()) ;; Object retVal = pjp.proceed (); If ((((("isObjectEmpty == true") () () () () () () () () () () (pad) Return rate; }   
  publicMethodInsideAClassMarkedWithResourceNotFound (รข ?? |)  method works when pointcut forms isspecified:  
  @Pointcut ("execution (Public * package.ctrippositiary +. * (..)) ")   
 However,  @ResourceNotFound  annotation can not be raised due to this fact The underlying class of the store interface is a (proxy)  SimpleJpaRepository  which is not particularly commented.  
 Is there a way to promote @Notfound Resources for implementation?  
 - Update -  
 The question has changed to reflect the fact that the advice (around) should apply only to the repository with custom annotations.  
  
 
 
 If you want to stop the repository call at the repository level, then you actually want to present custom annotations Not necessarily for him. You should be able to get this work done with a plain type match:  
  @Pointcut ("! Execution (Public Zero org.springframework.data.repository.Repository + * (. .)) ")   
 Execution of all non- zero  methods for all spring beams extending this Spring data  Repository  interface Will stop. / P> 
 can be found in a slightly related example.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
