        bookMasterServiceInterfacecontroller.addBook(bookMasterTable);
        return "bookadded";
    }
}

like that having all controller for each bean class

service interface

public interface BookMasterServiceInterface {
    public void addBook(BookMasterTable bookMasterTable);
}

service calss

@Service
public class BookMasterServiceInterfaceImpl implements BookMasterServiceInterface{
    @Autowired
    private BookMasterInterface bookMasterInterface;

    @Override
    @Transactional
    public void addBook(BookMasterTable bookMasterTable) {
        // TODO Auto-generated method stub
        bookMasterInterface.addBooks(bookMasterTable);

    }
}

like that having service for all bean

Repository class interface

public interface BookMasterInterface {
    public void addBooks(BookMasterTable bookMasterTable);
}

repository class implementation having for each bean

@Repository
public class BookMasterInterfaceImpl implements BookMasterInterface {
    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public void addBooks(BookMasterTable bookMasterTable) {
        // TODO Auto-generated method stub

        try {
            sessionFactory.getCurrentSession().save(bookMasterTable);
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
    }

}

and what error i am getting is.

i will be happy if u can help :)

i have four entities. first one is

@Entity
@Table(name = "tbl_bookmaster", uniqueConstraints = { @UniqueConstraint(columnNames = "bid") })
public class BookMasterTable {

    @Id
    @GeneratedValue
    @Column(name = "bid")
    private int bookid;

    @Column(name = "bookname")
    private String bookname;

    @Column(name = "booktype")
    private String booktype;

    @Column(name = "bookprice")
    private String bookprice;

    @Column(name = "bestsaler")
    private int bestsaller;

    @ManyToOne
    @JoinColumn(name = "lid")
    private LanguageMasterTable languageMasterTable;

    @ManyToOne
    @JoinColumn(name = "auid")
    private AutherMasterTable autherMasterTable;

    @ManyToOne
    @JoinColumn(name = "mailid")
    private EmailMasterTable emailMasterTable;

    public int getBookid() {
        return bookid;
    }

    public void setBookid(int bookid) {
        this.bookid = bookid;
    }

    public String getBookname() {
        return bookname;
    }

    public void setBookname(String bookname) {
        this.bookname = bookname;
    }

    public String getBooktype() {
        return booktype;
    }

    public void setBooktype(String booktype) {
        this.booktype = booktype;
    }

    public String getBookprice() {
        return bookprice;
    }

    public void setBookprice(String bookprice) {
        this.bookprice = bookprice;
    }

    public int getBestsaller() {
        return bestsaller;
    }

    public void setBestsaller(int bestsaller) {
        this.bestsaller = bestsaller;
    }

    public LanguageMasterTable getLanguageMasterTable() {
        return languageMasterTable;
    }

    public void setLanguageMasterTable(LanguageMasterTable languageMasterTable) {
        this.languageMasterTable = languageMasterTable;
    }

    public AutherMasterTable getAutherMasterTable() {
        return autherMasterTable;
    }

    public void setAutherMasterTable(AutherMasterTable autherMasterTable) {
        this.autherMasterTable = autherMasterTable;
    }

    public EmailMasterTable getEmailMasterTable() {
        return emailMasterTable;
    }

    public void setEmailMasterTable(EmailMasterTable emailMasterTable) {
        this.emailMasterTable = emailMasterTable;
    }

}

Answer 1

I think the problem is here, in AutherMasterTable (and similar places in other entities):

@Id
@GeneratedValue
@OneToMany
@JoinColumn(name = "auid")
private Set<BookMasterTable> bookMasterTables;

For a one-to-many join, the join column mentioned in the JoinColumn annotation is in the other table. It does not refer to a column in this table. Besides, a Set cannot be an identifier.

Try using two fields instead:

@Id
@GeneratedValue
@Column(name = "auid")
private int autherId;

@OneToMany
@JoinColumn(name = "auid")
private Set<BookMasterTable> bookMasterTables;

Note that we are not defining the same column twice in the same table: the first mention of auid above refers to a column in tbl_authermaster and the second one refers to the auid column in tbl_bookmaster.

Despite your mistake, Hibernate should not be throwing a NullPointerException at you. That is a bug in Hibernate.

Answer 2

Reading the stacktrace, you know where:

java.lang.NullPointerException
    at org.hibernate.cfg.Ejb3JoinColumn.checkReferencedColumnsType(Ejb3JoinColumn.java:538)
    at ...

You should run in debug with a breakpoint at that line, but I'd think that basically means you have an error in your entity, your mapping or on the database it's run on. If you can, you should generate the schema with Hibernate, then you should compare the difference between your target schema and the generated schema => that would print the mapping error.

Also there are no mappedBy on your OneToMany and ManyToOne. You should check that first (it is not an error to not have them, but it might become a problem if the database schema is not in sync with Hibernate expected schema).
