błąd z EntityManager (?) [solved]

0

Wydaje mi się że ten fragment kodu jest odpowiedzialny za generowanie błędu.

        entityManager.getTransaction().begin();
    	entityManager.persist(a);
    	entityManager.getTransaction().commit();

gdzie entityManager to protected EntityManager entityManager i a to jakaś klasa wygenerowana automatycznie przez Eclpise na podstawie tabeli z MySQL
Kod błędu:

HTTP Status 500 -

Rozumiem że wg ciebie pokazanie konfiguracji której używasz jest zbędne? Bo błąd leży właśnie tam. Poza tym czemu chcesz ręcznie otwierać i zamykać transakcje? https://javaee-spec.java.net/nonav/javadocs/javax/transaction/Transactional.html

Jeżeli masz transakcje z JTA w ramach kontenera EE to nie trzeba manualnie otwierać transakcji. Wystarczy oznaczyć metodę jako @Transactional i tyle.

Dopisanie do metody @Transactional nic nie pomogło. Teraz mam tak:

 
@Stateless
@Transactional
public class CalculatorImpl implements Calculator {

	 @PersistenceContext
	 protected EntityManager entityManager;
	 
	public double add(double x, double y) {
    	Composer a = new Composer();
    	//a.setId(1);
    	a.setForename("faf");
   
    
    	EntityManagerFactory emf = Persistence.createEntityManagerFactory("ProfessorService");
        EntityManager em = emf.createEntityManager();
        
        em.persist(a);
    	
        return x + y;
    }

}

Plik konfiguracyjny mam taki:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

        <properties>
            
         <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
         <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
         <property name="hibernate.show_sql" value="false"/>
        </properties> 
    </persistence-unit>
 
</persistence>

Błąd pojawia się taki:

To już dużo tłumaczy. EntityManager powinien zostać wstrzyknięty jako pole klasy z adnotacją @PersistanceContext bodajże (nie mam pod ręką dokumentacji).

Niemożliwe, ale działa :) Dziękuje!

Możliwe :) Poczytaj trochę tutoriale/specyfikację

Tu masz coś chyba nie tak, najpierw wstrzykujesz entity managera, a potem robisz to samo poprzez fabrykę. Usuń to drugie. Jeśli potrzebujesz różnych persistence unitów to wstrzyknij je za pomocą

@PersistenceUnit(name="ProfessorService") lub @PersistenceContext(name="ProfessorService")

 @PersistenceContext
     protected EntityManager entityManager;
 
    public double add(double x, double y) {
        Composer a = new Composer();
        //a.setId(1);
        a.setForename("faf");
 
 
        EntityManagerFactory emf = Persistence.createEntityManagerFactory("ProfessorService");
        EntityManager em = emf.createEntityManager();
 
        em.persist(a);
 
        return x + y;
    }

błąd z EntityManager (?) [solved]
