My DaoClass
`
#Repository
public class CityDao implements ICityDao {
#Autowired
SessionFactory sessionFactory;
#Override
#Transactional(readOnly=true)
public City getCityById(int id) {
City city = (City) sessionFactory.getCurrentSession().get(City.class, id);
Hibernate.initialize(city.getEvents());
return city;
}
}
`

I Have problem with My Dao Method.
getCityById(int id).
Hibernate throws Exception

com.globerry.project.dao.CityDaoTest.LazyTest() marked as Transactional. CityDao autowired. I saw a lot of examples, import all nessasary libraries, but it doesn't works.

OK, so i will just give you y configuration:
In folder WEB-INF i have 2 files:
1) hibernate-context.xml
content:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
">
<context:property-placeholder location="/WEB-INF/spring.properties"/>
<!-- Enable annotation style of managing transactions -->
<tx:annotation-driven transaction-manager="transactionManager"/>
<!-- <tx:annotation-driven/> -->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configLocation="${hibernate.config}"
p:packagesToScan="com.rasp.lta"/>
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${app.jdbc.driverClassName}"/>
<property name="url" value="jdbc:mysql://{url to database}"/>
<property name="username" value="{user name}"/>
<property name="password" value="{password}"/>
</bean>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory">
<qualifier value="transactionManager"/>
</bean>
</beans>
2) hibernate.cfg.xml
content:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
<property name="show_sql">true</property>
<!--<property name="create">update</property>-->
</session-factory>
</hibernate-configuration>
Then in WEB-INF i have folder: spring in which there is file root-context.xml, the content is:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<!-- Root Context: defines shared resources visible to all other web components -->
<import resource="../hibernate-context.xml"/>
</beans>
Additionally to have transaction in whole project, you should add to web.xml:
<filter>
<filter-name>hibernateFilter</filter-name>
<filter-class>org.springframework.orm.hibernate3.support.OpenSessionInViewFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>hibernateFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
<filter-name>encoding-filter</filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
And in the end in controller:
#Service("linkAddress")
#Transactional
public class LinkAddressService {
#Resource(name = "sessionFactory")
private SessionFactory sessionFactory;
public List<LinkAddressEntity> linkAddressEntityList(String linkList){
Session session = sessionFactory.getCurrentSession();
List<LinkAddressEntity> linkAddressList = (List<LinkAddressEntity>) session.getNamedQuery(LinkAddressEntity.QUERY_IN)
.setString("id", linkList).list();
return linkAddressList;
}
}
I hope it will be helpfull.
