java - How to add elements in a many-to-many relationship via Spring's @RepositoryRestResource REST API? -

-

I find it difficult to use the @RepositoryRestResource interface to create multiple-to-many relationships between the two Fairly simple institutions for For example, I have a relation with such a simple parent-child institution: 

  @public parents of the public class {@} @ generatedValue Private Long ID; @ManyToMany private list & lt; ChildEntity & gt; children; } @Entity Public Class ChildInty {@Id @GeneratedValue Private Long ID; @ManyToMany (mapped = "kids") private list & lt; ParentEntity & gt; mother-father; }   
 My treasures are using vanilla spring @RegositoryRRRSRSRSHatos API:    @RepositoryRestResource (collectionResourceRel = "parent", path = " Parents ") Public Interview Parent Repository Paging & Supporting Repository & lt; ParentEntity, Long & gt; {} @RepositoryRestResource (collectionResourceRel = "kids", path = "kids") Public interface hair regoratory paging and supporting repository & lt; ChildEntity, Long & gt; {}   
 I have been successful in using POST to create personal guard and child-building but I can not understand how to PUT / Patch the built-in interface Using both between  
 It seems that I should be able to use JSON like PUT to do something like  http: // localhost: 8080 / api / parents / 1 / children  But so far I'm not getting a structure that works.   
 
 
 I got an answer here:  
 Instead of JSON, "Content-Type: Using text "/ ure-list", it is possible to "add" a resource in the archive and put it in the URI with Put. You can remove the resource with a delete.  
 After some excavation, I came to know that Spring Documentation describes this:.

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
