Spring - No EntityManager with actual transaction available for current thread - cannot reliably process persist call

Question

I get this error when trying to invoke  persist  method to save entity model to database in my Spring MVC web application  Can t really find any post or page in internet that can relate to this particular error  It seems like something s wrong with EntityManagerFactory bean but i m fairly new to Spring programming so for me it seems like everything is initialized fine and according to

For anyone with the same issue as I had  I was calling a public method method1 from within another class  method1 then called another public method method2 within the same class  method2 was annotated with  Transactional  but method1 was not  All that method1 did was transform some arguments and directly call method2  so no DB operations here  The issue got solved for me once I moved the  Transactional annotation to method1  Not sure the reason for this  but this did it for me

Without  Transactional annotation you can achieve the same goal with finding the entity from the DB and then removing that entity you got from the DB  CrudRepositor - gt  void delete T var1

If you have    Transactional    Spring Transactional class MyDao extends Dao       and super-class  class Dao       public void save Entity entity    getEntityManager   merge entity         and you call   Autowired MyDao myDao  myDao save entity     you won t get a Spring TransactionInterceptor  that gives you a transaction    This is what you need to do    Transactional  class MyDao extends Dao       public void save Entity entity    super save entity         Unbelievable but true

This error had me foxed for three days  the situation I faced produced the same error  Following all the advice I could find  I played with the configuration but to no avail   Eventually I found it  the difference  the Service I was executing was contained in a common jar  the issue turned out to be AspectJ not treating the Service instantiation the same  In effect the proxy was simply calling the underlying method without all the normal Spring magic being executed before the method call   In the end the  Scope annotation placed on the service as per the example solved the issue    Service  Scope proxyMode   ScopedProxyMode INTERFACES   Transactional public class CoreServiceImpl implements CoreService        PersistenceContext     protected EntityManager entityManager        Override     public final  lt T extends AbstractEntity gt  int deleteAll Class lt T gt  clazz            CriteriaDelete lt T gt  criteriaDelete   entityManager getCriteriaBuilder   createCriteriaDelete clazz           criteriaDelete from clazz           return entityManager createQuery criteriaDelete  executeUpdate               The method I have posted is a delete method but the annotations affect all persistence methods in the same way   I hope this post helps someone else who has struggled with the same issue when loading a service from a jar

I got this exception while attempting to use a deleteBy custom method in the spring data repository  The operation was attempted from a JUnit test class   The exception does not occur upon using the  Transactional annotation at the JUnit class level

I had this issue for days and nothing I found anywhere online helped me  I m posting my answer here in case it helps anyone else   In my case  I was working on a microservice being called through remoting  and my  Transactional annotation at the service level was not being picked up by the remote proxy   Adding a delegate class between the service and dao layers and marking the delegate method as transactional fixed this for me

I got the same error when I executed the Spring JPA deleteAll   method from Junit test cases  I simply used the deleteInBatch    amp  deleteAllInBatch   and its perfectly works  We do not need to mark  Transactional at the test cases level

I had the same problem and I annotated the method as  Transactional and it worked   UPDATE  checking the spring documentation it looks like by default the PersistenceContext is of type Transaction  so that s why the method has to be transactional  http   docs spring io spring docs current spring-framework-reference html orm html       The  PersistenceContext annotation has an optional attribute type    which defaults to PersistenceContextType TRANSACTION  This default is   what you need to receive a shared EntityManager proxy  The   alternative  PersistenceContextType EXTENDED  is a completely   different affair  This results in a so-called extended EntityManager    which is not thread-safe and hence must not be used in a concurrently   accessed component such as a Spring-managed singleton bean  Extended   EntityManagers are only supposed to be used in stateful components   that  for example  reside in a session  with the lifecycle of the   EntityManager not tied to a current transaction but rather being   completely up to the application

Just a note for other users searching for answers for thie error  Another common issue is      You generally cannot call an  transactional method from within the same class     There are ways and means using AspectJ but refactoring will be way easier   So you ll need a calling class and class that holds the  transactional methods

Adding the org springframework transaction annotation Transactional annotation at the class level for the test class fixed the issue for me

I had the same error because I switched from XML- to java-configuration   The point was  I didn t migrate  lt tx annotation-driven  gt  tag  as Stone Feng suggested   So I just added  EnableTransactionManagement as suggested here Setting Up Annotation Driven Transactions in Spring in  Configuration Class  and it works now
