I am using tapestry 5 with spring boot using this large small library: https://github.com/code8/tapestry-boot
However, I get the notorious LazyInitializationException, despite using OpenSesionInViewFilter. Pros and cons of OpenSesionInViewFilter aside, I would like this to work with OpenSesionInViewFilter as I am porting a large legacy application.
My spring boot configuration
@SpringBootApplication
public class Launcher {
public static void main(String[] args) {
new SpringApplicationBuilder(Launcher.class)
.web(true)
.run(args);
}
@Bean
public HibernateJpaSessionFactoryBean sessionFactory() {
return new HibernateJpaSessionFactoryBean();
}
@Bean
public FilterRegistrationBean registerOpenSessionInViewFilterBean() {
FilterRegistrationBean registrationBean = new FilterRegistrationBean();
OpenSessionInViewFilter filter = new OpenSessionInViewFilter();
registrationBean.setFilter(filter);
registrationBean.setOrder(5);
return registrationBean;
}
}
I made sure that the OpenSessionInViewFilter loads before TapestryFilter and checks this with spring output at boot. I edited the tapestry download library for setOrder (10) in TapestryFilter.
, OpenSessionInViewFilter .
LIE , OpenSessionInViewFilter.

Tapestry Pages --> XXManagerImpl (e.g, UserManager) --> JpaRepository

@Service
@Transactional(propagation = Propagation.REQUIRED)
public class UserManagerImpl implements UserManager, Serializable
JpaRepositories @Transactional @Repository ( , ).
