我所有的字段都有一个前缀。 我该如何告诉它休眠？

Question

Eg I have:

  @Column(name = "username")
  private String m_username;

Note that the @Column annotation only affects the database column name.

Hibernate still thinks the name of the property is 'm_username'.

How can I tell Hibernate that the property name is just 'username'?

Please tell me there is a way to do this...

Edit: I removed the @AccessType annotation in my code example, as it is not relevant for this question.

Update: After switching everything to field access, this exception happens:

org.hibernate.QueryException: could not resolve property: username of: mypackage.model.User

It happens here:

Criteria criteria = session.createCriteria(User.class);
criteria.add(Restrictions.eq("username", username));
User result = (User) criteria.uniqueResult();

And the reason is most likely that hibernate only 'knows' of a property called 'm_username', while I think of it and program against a property named 'username'. Also note that my getters/setters are called: "getUsername()" and "setUsername(String value)" (automatically generated).

Answer 1

why do you use AccessType.PROPERTY ?

remove it and it is accessed by 'field'.

do not mix field and property annotations. stick to one or the other.

Answer 2

As per my knowledge we can't* .

There is still one issue with the way hibernate looks up the methods for a given property name .

Suppose you have a property with a name like "mProperty" (first lowercase, second uppercase, rest doesn't matter). Not the accessor methods in the source code will be getMProperty and setMProperty .

The way BasicPropertyAccessor.getterMethod is implemented in that way .

Answer 3

I found one lead here: https://forum.hibernate.org/viewtopic.php?f=1&t=943110

But the thread is 7 years old and I don't know how to apply this to annotation based configuration (I don't have an xml configuration file).
