问题
I'm using Wicket in combination with Spring and Hibernate, at least that's what I'm trying to do, the problem comes with auto generating the tables with Hibernate annotations.
I've been trying many changes in the configuration but can't seem to figure out why my configuration doesn't generate any tables. And I'm hoping someone can point me in the right direction, even about the Spring configuration I'm not sure.
I've included all the files I'm using to try to make this work in links, so that it won't be a very long list of configuration files.
I'm using the following class with annotations, http://schrealex.com/downloads/User.java:
@Entity
@Table(name="user")
public class User {
@Id
@Column(name="user_id", unique=true, nullable=false)
@GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
@Column(name="username")
private String username;
@Column(name="password")
private String password;
@Column(name="firstname")
private String firstname;
@Column(name="lastname")
private String lastname;
@Column(name="birthDate")
private Date birthDate;
@Column(name="email")
private String email;
@Column(name="profile_image")
private String profile_image;
public User() {
}
public User(String username, String password, String email) {
this.username = username;
this.password = password;
this.email = email;
}
// Getter and Setter methods
}
I'm using the following dependencies described in my pom.xml:
http://schrealex.com/downloads/pom.xml
I'm using the following configuration in applicationContext.xml and properties:
http://schrealex.com/downloads/application.properties
http://schrealex.com/downloads/applicationContext.xml
And finally web.xml:
http://schrealex.com/downloads/web.xml
If I'm missing any files you'd like to see, just ask.

Edit :-
I tried renaming my User class to MediaUser and the @Table annotation to mediaUser to avoid problems with the USER word being reserved for some databases.
What I've found from the start up logging, as seen above, is that it does say it's running the export:
INFO - SchemaExport - Running hbm2ddl schema export
INFO - SchemaExport - exporting generated schema to database
INFO - SchemaExport - schema export complete
Also tried different approaches to the Hibernate annotations, like using other imports, @Table is now used by importing javax.persistence.Table, but I also tried the Hibernate org.hibernate.annotations.table, thus far without a solution to my problem.
回答1:
I've found the answer to my problem, the annotations need either be set on the instance variables or on the class and it's methods and it needs to implement Serializable like:
@Entity
public class User implements Serializable {
@Id
@GeneratedValue
private Long id;
private String username;
private String password;
private String firstname;
private String lastname;
private Date birthDate;
private String email;
private String profileImage;
public User() {
}
public User(String username, String password, String email) {
this.username = username;
this.password = password;
this.email = email;
}
// Getter and Setter methods
@Column
public getUsername() {
return username;
}
@Column
public getPassword() {
return password;
}
@Column
public getFirstname() {
return firstname;
}
@Column
public getLastname() {
return lastname;
}
@Column
@Temporal(TemporalType.TIME)
public getBirthDate() {
return birthDate;
}
@Column
public getEmail() {
return email;
}
@Column
public getProfileImage() {
return profileImage;
}
}
回答2:
I had the same problem ... in my case, the problem was because the USER word is reserved for some data bases.
So, considering that your hibernate configuration files are right, just add a prefix in all your tables and the problem was solved.
I hope this solve your problem too =)
回答3:
Try to use
@EntityScan({" yourentitypackagehere "})
in your springboot application
