I tried to see all the questions on this topic but none of them helped me, I have tried all possible way to resolve the issue, but not able to.I want to understand where I have done mistake in my code.
My project structure is
hibernateOnline
|---------src/main/java
|------------com.hibernateOnline.data
|---------HibernateUtil.java
|------------com.hibernateOnline.data.entities
|------------------User.java
|---------src/main/resources
|------------hibernate.cfg.xml
Below is my User class where I have used all the JPA annotation not specific to hibernate
package com.hibernateOnline.data.entities;
@Entity
@Table(name = "finances_user")
public class User
{
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="USER_ID")
private Long userId;
@Column(name="FIRST_NAME")
private String firstName;
@Column(name="LAST_NAME")
private String lastName;
@Column(name="BIRTH_DATE")
private Date birthDate;
@Column(name="EMAIL_ADDRESS")
private String emailAddress;
@Column(name="LAST_UPDATED_DATE")
private Date lastUpdatedDate;
@Column(name="LAST_UPDATED_BY")
private String lastUpdatedBy;
@Column(name="CREATED_DATE")
private Date createdDate;
@Column(name="CREATED_BY")
private String createdBy;
public Long getUserId() {
return userId;
}
public void setUserId(Long userId) {
this.userId = userId;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public Date getBirthDate() {
return birthDate;
}
public void setBirthDate(Date birthDate) {
this.birthDate = birthDate;
}
public String getEmailAddress() {
return emailAddress;
}
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
public Date getLastUpdatedDate() {
return lastUpdatedDate;
}
public void setLastUpdatedDate(Date lastUpdatedDate) {
this.lastUpdatedDate = lastUpdatedDate;
}
public Date getCreatedDate() {
return createdDate;
}
public void setCreatedDate(Date createdDate) {
this.createdDate = createdDate;
}
public String getCreatedBy() {
return createdBy;
}
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
public String getLastUpdatedBy() {
return lastUpdatedBy;
}
public void setLastUpdatedBy(String lastUpdatedBy) {
this.lastUpdatedBy = lastUpdatedBy;
}
}
Next is the HibernateUtils class where I am creating the sessionFactory
package com.hibernateOnline.data;
public class HibernateUtil
{
private static final SessionFactory sessionFactory = buildSessionFactory();
private static SessionFactory buildSessionFactory() {
try {
Configuration configuration = new Configuration();
configuration.configure();
return configuration
.buildSessionFactory(new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties())
.build());
} catch (Exception e) {
e.printStackTrace();
throw new RuntimeException(
"There was an error building the factory");
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}
Now the configuration file "hibernate.cfg.xml" which I am using for configuration of MySQL database and to mapped the User class
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- Database connection settings -->
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/hibernatedb</property>
<property name="connection.username">****</property>
<property name="connection.password">*****</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>
<!-- Echo all executed SQL to stdout -->
<property name="show_sql">true</property>
<mapping class="com.hibernateOnline.data.entities.User"/>
</session-factory>
</hibernate-configuration>
After done with all those things when I am trying to run the program it showing below error it is not able to find out the User class
DEBUG - begin

Can anyone please help me out to solve this problem??
