This is regarding Spring OpenSessionInViewFilter using with @Transactional annotation at service layer.
i went through so many stack overflow post on this but still confused about whether i should use OpenSessionInViewFilter or not to avoid LazyInitializationException
It would be great help if somebody help me find out answer to below queries.
Is it bad practice to use OpenSessionInViewFilter in application
having complex schema.
using this filter can cause N+1 problem
if we are using OpenSessionInViewFilter does it mean @Transactional not required?
Below is my Spring config file
<context:component-scan base-package="com.test"/>
<context:annotation-config/>
<bean id="messageSource"
class="org.springframework.
context.support.ReloadableResourceBundleMessageSource">
<property name="basename" value="resources/messages" />
<property name="defaultEncoding" value="UTF-8" />
</bean>
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
p:location="/WEB-INF/jdbc.properties" />
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
p:driverClassName="${jdbc.driverClassName}"
