私は明確な実例と良いガイドを見つけるのが難しいと思っているので、これらの技術に精通するために一歩一歩試しています。hibernate 5.2.2（entity annotation）+ mysql、eclipseの最初の例
私は、正しくを、プログラムを実行するために私のできないことを明確にする必要があり、可能な解決策は、このようなコードを実行できるようにする：
1）私のディレクトリとライブラリのプリントアウト： eclipse project
2）これは、SRC/hibernate.cfg.xmlののコードである：これは、Src/PK/Student.javaのコードである）
<hibernate-configuration>
<session-factory>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/prva?useSSL=false</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>
<property name="connection.pool_size">1</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="current_session_context_class">thread</property>
<!-- note: rimbalza Echo SQLquery su stdoout -->
<property name="show_sql">true</property>
</session-factory>
</hibernate-configuration>
3： （永続クラス）
package pk;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="student")
public class Student {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="id")
private int id;
@Column(name="first_name")
private String firstName;
@Column(name="last_name")
private String lastName;
@Column(name="email")
private String email;
public Student() {
}
public Student(String firstName, String lastName, String email) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
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 String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return "Student [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", email=" + email + "]";
}
}
4）これは、Src/PK/Play.javaのコードである： （メイン及び学生の使用）
package pk;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class Play {
public static void main(String[] args) {
SessionFactory factory = new Configuration()
.configure()
.addAnnotatedClass(Student.class)
.buildSessionFactory();
Session session=factory.getCurrentSession();
try{
Student tempStudent = new Student("Carl","Dred","[email protected]");
session.beginTransaction();
session.save(tempStudent);
session.getTransaction().commit();
tempStudent.toString();
}finally{
factory.close();
}
}
}
