我就是想测试一下spring+hibernate,网上有的教程提到了spring+hibernate 时的事务处理,有的提都没提,貌似也能通过,不知道是不是版本问题...但我明明加了事务处理,运行的时候还是报错:
Testcase: testGetUserByName(db.sample.dao.UmUserDAO.UmUserDAOTest): Caused an ERROR
No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

at db.sample.dao.UmUserDAO.UmUserDAO.getUserByName(UmUserDAO.java:34)
at db.sample.dao.UmUserDAO.UmUserDAOTest.testGetUserByName(UmUserDAOTest.java:50)
我用的是netbean 6.5,spring 2.5,hibernate 3.2,mysql
spring 的配置如下

[/code]
entity bean文件是netbean自动生成的,应该没什么问题,我只不过让他继承了一个我指定的 BasePO类,这个类是implements java.io.Serializable的
BaseDAO 如下,很简单[code="java"]
import org.hibernate.SessionFactory;
public abstract class BaseDAO
implements IBaseDAO {
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
}
[/code]
具体实现的interface:
[code="java"]
package db.sample.dao.UmUserDAO.intf;
import db.sample.model.UmUser.UmUser;
/**
*
- @author Administrator */ public interface IUmUserDAO { public UmUser getUserByName(String username); } [/code]
这个interface 的实现:
[code="java"]
/*
- To change this template, choose Tools | Templates
- and open the template in the editor. */
package db.sample.dao.UmUserDAO;
import db.sample.dao.UmUserDAO.intf.IUmUserDAO;
import db.sample.model.UmUser.UmUser;
import db.base.BaseDAO;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.*;
/**
*
- @author Administrator */
@Transactional(readOnly = true)
public class UmUserDAO
implements IUmUserDAO{
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
public UmUser getUserByName(String username)
{
UmUser user=(UmUser)this.getSessionFactory().getCurrentSession().createQuery("from um_user user where user.username=\"?\"").setParameter(0, username).list().get(0);
return user;
}
}
[/code]
最后是测试类
[code="java"]
/*
- To change this template, choose Tools | Templates
- and open the template in the editor. */
package db.sample.dao.UmUserDAO;
import db.sample.model.UmUser.UmUser;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import static org.junit.Assert.*;
import org.springframework.context.support.FileSystemXmlApplicationContext;
/**
*
-
@author Administrator
*/
public class UmUserDAOTest {public UmUserDAOTest() {
}@BeforeClass
public static void setUpClass() throws Exception {
}@AfterClass
public static void tearDownClass() throws Exception {
}@Before
public void setUp() {
}@After
public void tearDown() {
}/**
- Test of getUserByName method, of class UmUserDAO. */ @Test public void testGetUserByName() { System.out.println("getUserByName"); String username = "guest"; FileSystemXmlApplicationContext appContext = new FileSystemXmlApplicationContext(new String[]{"src/META-INF/Spring.xml"}); UmUserDAO instance = (UmUserDAO)appContext.getBean("umUserDAO"); UmUser result = instance.getUserByName(username); //assertEquals(expResult, result); // TODO review the generated test code and remove the default call to fail. // fail("The test case is a prototype."); }
}
[/code]
其实我感觉应该是spring.xml 有问题,但实在看不出来在什么地方,
顺便说一下,我用的是glassfish2.0,应该没什么影响吧?...
[b]问题补充：[/b]
存在的啊
db.sample.dao.UmUserDAO.intf.IUmUserDAO
就是那个interface..
