我是 spring 新手，所以我不知道所有配置是否正确。虽然我使用了 spring IDE 和提供的单元测试是正确的。
我有一个用户类
@Entity
@NamedQuery(name="findUser4Email",
query="SELECT * " +
"FROM User " +
"WHERE email = :userEmail")
public class User extends AbstractNamedDomain {
private String name;
private String email;
private String password;
...
我想通过数据库保持这个类的持久性。我使用 hsqldb 将查询发送到我的数据库等等。
现在我的用户有一个 DAO 层，如下所示：
public class UserManager implements IUserManager {
@PersistenceContext
private EntityManager em;
public User findUser4Email(String email) {
return (User) em.createNamedQuery("findUser4Email").setParameter("userEmail",
email).getSingleResult();
}
public User storeUser(User user) {
//User u = em.merge(user);
em.persist(user);
return user;
}
...
my beans look like this :
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

When I try to store a User in a unittest (just by calling the store(User) from the dao the test fails. Nor do I see any table created in my DB when I look at it with hsqldb. What is wrong my code ? Or what do I miss?
this is what my datasourcebean looks like
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="url" value="${jdbc.url}"/>
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>
