JPA - Override bean validation in joined-strategy inheritance -

-

I have three JPA entities: A, B and C. Is it possible to override the Bean Validation barrier in subclasses? For example, I would like to get a @not tap in a field and get a non-obligation in the same area for C.

I was thinking of doing this using the Bean Validation group, but I do not know how to define B with another group and with C, the second group should be valid.

Code to clarify the problem: 

  @Entity @Inheritance (strategy = inheritance type. Jind) ... public abstract class A {... @ column (Name = "field") private integer field; ...} @Entity Public Class B expanded in a {... // @ NotNull field ...} @Antity LocalCc in a {... // @ Null field in ...}    
 
 
 I think I came to a solution to read this second question about conditional bean verification I am ..  
 It has not been tested yet, but I think it could work.  
 The solution code:  
  @Entity @Inheritance (strategy = InheritanceType.JOINED) ... Public abstract class A {... @ column (name = "FIELD ") Private Integrity Field; ...} @Entity Public Class B's extension A {... @transient @AssertTrue is private boolean ValidClassA () {returns (getField ()! = Null); // valid is not valid ...}} @Entity public class C extension A {... @Transient @AssertTrue is private boolean ValidClassA () {returns (getField () == blank); // valid tap} ...}

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.
