spring-boot - example - spring boot inject hibernate session

No CurrentSessionContext configurado

Question

perdón por mal inglés. Comienzo mi proyecto con spring-boot 1.1.8 , Excepción Encuentro No CurrentSessionContext configured , luego hice una búsqueda, <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property> propiedad <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property> podría resolver este problema, pero

cómo configurar esta propiedad usando la clase java?

actualización: Cambié a la forma Hibernate4.x de definir SessionFactory pero aún tengo el mismo error, ¡por favor ayuda!

Usa java 1.8 y speing boot 1.1.8

aquí está mi pom.xml

Answer 1

Su configuración y uso de hibernación es incorrecta. Está utilizando Spring e incluso mejor Spring Boot, sin embargo, lo que ha publicado trata de no usar esos frameworks y trata de evitarlos. Sugiero usar Spring Boot y dejar que configure las cosas por ti.

Primero borre sus HibernateUtils , entiérrelo y nunca lo vuelva a mirar. También puede eliminar su AppConfig ya que Spring Boot puede y se hará cargo de DataSource .

A continuación, cree un archivo llamado application.properties en su directorio src/main/resources y coloque el siguiente contenido allí.

spring.datasource.url=jdbc:mysql://localhost/mysql
spring.datasource.username=root
spring.datasource.password=

Esto configurará automáticamente un DataSource para usted. No necesita el controlador como se deduce de la url que proporciona. A continuación, agregue las siguientes propiedades para configurar JPA.

spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

Para obtener más configuraciones y propiedades, sugiero leer la Guía de referencia de Spring Boot para ver las propiedades de esta lista completa .

Luego, en su WebApplicationStarter agregue HibernateJpaSessionFactoryBean para exponer el JPA EntityManagerFactory creado como SessionFactory .

@Configuration
@EnableAutoConfiguration
@ComponentScan("com.mytest")
public class WebApplicationStarter extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(WebApplicationStarter.class);
}
public static void main(String[] args) throws Exception {
ApplicationContext context = SpringApplication.run(WebApplicationStarter.class, args);
}
@Bean
public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
return hemf.getSessionFactory();
}
}

Luego simplemente @Autowire the SessionFactory en su UserServiceImpl .

@Service
@Transactional
public class UserServiceImpl implements UserService {
@Autowired
private SessionFactory sessionFactory;
}

Ahora solo puede usar SessionFactory .
