I'm trying to set up my project using Spring 3.1 and Hibernate 4. I've been following some tutorials online. I'm getting a strange error that according to the spring forums should have been fixed with Spring 3.1. Spring Bug Tracker
When my service calls getCurrentSession(), it throws the following exception:
org.hibernate.HibernateException: **No Session found for current thread**] with root cause org.hibernate.HibernateException: No Session found for current thread
at org.springframework.orm.hibernate4.SpringSessionContext.currentSession(SpringSessionContext.java:97) at
org.hibernate.internal.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:881)
****EDIT: updated my spring-dao.xml according to the Spring Spring 3.1 Documentation for Transactions. I've tried swapping out my datasource with a org.apache.commons.dbcp.BasicDataSource. Are there any properties I am missing from my configuration that could be causing this? ****
Here's my spring-dao.xml:
<!-- Enable annotation style of managing transactions -->
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<value>hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect</value>
</property>
</bean>
<!-- Declare a datasource that has pooling capabilities-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close"
p:driverClass="${app.jdbc.driverClassName}"
p:jdbcUrl="${app.jdbc.url}"
p:user="${app.jdbc.username}"
p:password="${app.jdbc.password}"
p:acquireIncrement="5"
p:idleConnectionTestPeriod="60"
p:maxPoolSize="100"
p:maxStatements="50"
p:minPoolSize="10" />
<!-- Declare a transaction manager-->
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory" />
My User bean (User.java)
package com.foo.lystra.beans;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="users")
public class User implements Serializable {
private static final long serialVersionUID = -5527566191402296042L;
@Id
@Column(name = "idusers")
private Integer user_id;
@Column(name="login_name")
private String loginName;
@Column(name="password")
private String password;
@Column(name="role")
private String role;
@Column(name="congregation_id")
private Integer congregation_id;
public Integer getUser_id() {
return user_id;
}
public void setUser_id(Integer user_id) {
this.user_id = user_id;
}
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public Integer getCongregation_id() {
return congregation_id;
}
public void setCongregation_id(Integer congregation_id) {
this.congregation_id = congregation_id;
}
public String toString() {
return "user_name: " + this.loginName + " congregation_id: " + this.congregation_id.toString();
}
}
And finally my service...
package com.foo.lystra.services;
import java.util.List;
import javax.annotation.Resource;
import org.apache.commons.logging.LogFactory;
import org.apache.commons.logging.Log;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.foo.lystra.beans.User;
import com.foo.lystra.beans.Congregation;
@Service("congregationUserService")
@Transactional
public class CongregationUserService {
protected static Log logger = LogFactory.getLog(CongregationUserService.class);
@Resource(name="sessionFactory")
private SessionFactory sessionFactory;
public List<User> getAllUsers() {
logger.debug("getting all users");
//Exception is thrown on this next line:
Session session = sessionFactory.getCurrentSession();
Query query = session.createQuery("FROM users");
return query.list();
}
}
I realize that my datasource is probably not getting used. If I have forgotten to include any configurations I can update this post. Also if the Tomcat startup logs are needed I can provide them as well.
