我得到了这个异常，但我不知道我的配置有什么问题 我正在发布相关文件，感谢您的帮助
我在用 Spring 3.1.0.RELEASE hibernate-entitymanager 3.6.10.Final(应该与 JPA 2 一起使用)

尝试从 JUnit 文件运行代码

package com.successcharging.core.dao.jpa;

import junit.framework.Assert;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;

import com.successcharging.core.security.dao.UserDao;
import com.successcharging.core.security.model.User;
import com.successcharging.core.security.model.UserImp;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {
    "classpath:applicationContext/applicationContext*.xml"})
@TransactionConfiguration(transactionManager="transactionManager", defaultRollback=true)
@Transactional
public class UserDaoImplTest {

private static final boolean ENABLED = true;

private static final String PASSWORD = "password";

private static final String USERNAME = "joe.bloggs";

@Autowired
private UserDao userDao;
private User user;
@Before
public void before() {
    user = new UserImp();
    user.setName(USERNAME);
    user.setPassword(PASSWORD);
    user.setEnabled(ENABLED);

    userDao.save(user);
}

@Test
public void findByUserName() {
    Assert.assertNotNull(user);
    User user2 = userDao.findById(user.getId());

    Assert.assertNotNull(user2);
    Assert.assertEquals(USERNAME, user2.getName());
}
}

最佳答案

我发现了我必须将数据源添加到 persistenceUnitManager 中的问题

<property name="persistenceUnitManager">
    <bean class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManag‌​er">
        <property name="defaultDataSource" ref="dataSource" />
    </bean>
</property>
