我正在尝试更新用户实体及其正在更新：
请参考以下代码： Hibernate 映射文件：
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="sg.edu.nus.iss.phoenix.user.entity.User" table="user">
<id name="id" column="UserId">
</id>
<property name="password" column="Password" type="string"
update="false" />
<property name="name" column="Name" type="string"
update="false" />
<property name="status" column="Status" type="string" />
</class>
</hibernate-mapping>
用户.java
public class User implements Cloneable, Serializable {
/**
* For eclipse based unique identity
*/
private static final long serialVersionUID = -3737184031423373198L;
/**
* Persistent Instance variables. This data is directly mapped to the

private String id;
private String password;
private String name;
// private UserTypeEnum status;
private String status;
private List<Role> roles = new ArrayList<Role>();
/**

*/
public User() {
}
public User (String userId, String password){
this.id = userId;
this.password = password;
this.roles = new ArrayList<Role>();
}
public User (String userId, String password, String name){
this.id = userId;
this.password = password;
this.name = name;
this.status = "Active";
this.roles = new ArrayList<Role>();
}
public User(String idIn) {
this.id = idIn;
}
/**

* not make any checks against malformed data, so these might require some
* manual additions.
*/
public String getId() {
return this.id;
}
public void setId(String idIn) {
this.id = idIn;
}
public String getPassword() {
return this.password;
}
public void setPassword(String passwordIn) {
this.password = passwordIn;
}
public String getName() {
return this.name;
}
public void setName(String nameIn) {
this.name = nameIn;
}
public String getStatus() {
return status;
}
/*
public void setStatus(UserTypeEnum status) {
this.status = status;
}
*/
public void setStatus(String status)
{
this.status=status;
}
public List<Role> getRoles() {
return roles;
}
public void setRoles(List<Role> roles) {
this.roles = roles;
}
}
UserDAOImpl.java
public class UserDaoImpl implements UserDao {
@Override
public boolean update(User t) throws SQLException {
boolean status;
try{
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.saveOrUpdate(t);
session.flush();
session.refresh(t);
tx.commit();
session.close();
status = true;
}catch (HibernateException e) {
e.printStackTrace();
status=false;
}
return status;
}
--------
}
Junit-测试：
@Test
public void testUpdate() throws SQLException {
presenter1.setName("PREE");
boolean status = userDao.update(presenter1);
List<User> users = userDao.searchMatching(presenter1);
String name = users.get(0).getName();
assertEquals(name, "PREE");
}
在设置中，我正在创建 Presenter1，如下所示：
// Create user
presenter1 = new User(PRESENTER1, PASSWORD, PRESENTER_NAME1);
//session.saveOrUpdate(presenter1);
userDao.create(presenter1);
请让我知道它为什么不更新实体。
