Hibernate下搭建JUNIT的测试环境，使用beforeclass和afterclass实现sessionFactory建立一次
sessionFactory建立一次除了beforeclass和afterclass，还有单例，static语句块两种方法
实体类：
package com.zzk.hibernate.model;
import javax.persistence.Entity;
import javax.persistence.Id;
@Entity
public class Teacher {
private int id;
private String name;
private String title;
@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
测试类：
package com.zzk.hibernate.model;
import static org.junit.Assert.*;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.BeforeClass;
import org.junit.Test;
public class TeacherTest {
private static SessionFactory sf = null;
@BeforeClass
public static void beforeClass() {
//防止出现Junit的“静默”BUG的方法一
try {
sf = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@After
public void tearDown() throws Exception {
}
@Test
public void testTeacherSave() {
Teacher t = new Teacher();
t.setId(1);
t.setName("t1");
t.setTitle("中级");
Session session = sf.openSession();
session.beginTransaction();//执行操作
session.save(t);
session.getTransaction().commit();//提交
session.close();
}
//解决JUNIT"静默"BUG的方法二
// public static void main(String[] args) {
// beforeClass();
// }
//
@AfterClass
public static void afterClass() {
sf.close();
}
}
