How to load ApplicationContext java-config in Junit - spring

Question

I am trying to move spring xml config to java config. Right now, I am able to make everything work, except one thing, that is to run junit on my services. The problem is that my junit test couldn't detect application context. Hence, how I can load application context java-based config in Junit? Since I can run my service on a browser, I assume that my integration is correct, meaning that my test configuration is not right, but I can't find where is my be wrong.
This is my junit config:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(
classes={Bootstrap.class, RootContextConfig.class
, WebServletContextConfig.class, PersistenceConfig.class })
#WebAppConfiguration
//#TransactionConfiguration(transactionManager="transactionManager",defaultRollback=true)
public class BaseTest { ... }
Just in case, I include my application context configuration here also.
This is my bootstrap
public class Bootstrap implements WebApplicationInitializer
{
#Override
public void onStartup(ServletContext container)
throws ServletException {
AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
rootContext.register(RootContextConfig.class);
container.addListener(new ContextLoaderListener(rootContext));
AnnotationConfigWebApplicationContext servletContext = new AnnotationConfigWebApplicationContext();
servletContext.register(WebServletContextConfig.class);
ServletRegistration.Dynamic dispatcher = container.addServlet(
"SpringDispatcher", new DispatcherServlet(servletContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
My RootContext
#Configuration
#EnableScheduling
#EnableAsync(
mode=AdviceMode.PROXY, proxyTargetClass=false,
order=Ordered.HIGHEST_PRECEDENCE
)
#ComponentScan(
basePackages={"com.core", "com.common"},
excludeFilters=#ComponentScan.Filter(Controller.class)
)
#Import({PersistenceConfig.class})
public class RootContextConfig {...}
My WebServletContext
#Configuration
#EnableWebMvc
#ComponentScan(
basePackages = { "com.web" },
useDefaultFilters = false,
includeFilters = #ComponentScan.Filter({Controller.class, ControllerAdvice.class})
)
public class WebServletContextConfig extends WebMvcConfigurerAdapter {..}
My PersistentContext
#Configuration
#EnableTransactionManagement(
mode=AdviceMode.PROXY, proxyTargetClass=false
, order=Ordered.LOWEST_PRECEDENCE)
public class PersistenceConfig {
#Bean
public DataSource customerSupportDataSource() {
//JndiDataSourceLookup lookup = new JndiDataSourceLookup();\
BasicDataSource basic = new BasicDataSource();
basic.setDriverClassName(KEY_DRIVER_CLASS);
basic.setUrl(KEY_DB_URL);
basic.setUsername(KEY_DB_USERNAME);
basic.setPassword(KEY_DB_PASSWORD);
return basic;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
{
Map<String, Object> properties = new Hashtable<>();
properties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabasePlatform("org.hibernate.dialect.PostgreSQLDialect");
adapter.setGenerateDdl(true);
adapter.setShowSql(true);
LocalContainerEntityManagerFactoryBean factory =
new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setDataSource(this.customerSupportDataSource());
factory.setPackagesToScan("com.common.model");
factory.setSharedCacheMode(SharedCacheMode.ENABLE_SELECTIVE);
factory.setValidationMode(ValidationMode.NONE);
factory.setJpaPropertyMap(properties);
return factory;
}
#Bean
public PlatformTransactionManager jpaTransactionManager()
{
return new JpaTransactionManager(
this.entityManagerFactoryBean().getObject()
);
}
