Class TransactionalRequest

java.lang.Object

io.jooby.hibernate.TransactionalRequest

All Implemented Interfaces:

Route.Decorator, Serializable

public class TransactionalRequest
extends Object
implements Route.Decorator

Attach Session and EntityManager to the current request. The route pipeline runs inside a transaction which is commit on success or rollback in case of exception. Once route pipeline is executed the session/entityManager is detached from current request and closed it. Usage:

 {

   install(new HikariModule());

   install(new HibernateModule());

   decorator(new TransactionalRequest());

   get("/handle", ctx -> {
     EntityManager handle = require(EntityManager.class);
     // work with handle.
   });
 }
 

NOTE: This is NOT the open session in view pattern. Persistent objects must be fully initialized to be encoded/rendered to the client. Otherwise, Hibernate results in LazyInitializationException.

Since:

2.0.0
