錯誤創建名爲'bookMasterController'的Bean的錯誤：注入自動裝配的依賴關係失敗;

-1

我使用的是Spring 3.2和Hibernate，但是我發現它不允許從XML文件創建SessionFacotry bean，我不知道爲什麼會出現這個錯誤。我有搜索很多，但沒有找到優秀答案請幫助相同。錯誤創建名爲'bookMasterController'的Bean的錯誤：注入自動裝配的依賴關係失敗;

控制器豆

@Controller 
public class BookMasterController { 

    @Autowired 
    private BookMasterServiceInterface bookMasterServiceInterfacecontroller; 


    @RequestMapping(value="/addbook",method= RequestMethod.POST) 
    public String addAuther(@ModelAttribute("book") BookMasterTable bookMasterTable){ 

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

像對於每個bean類

服務接口

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

服務CALSS

具有所有控制器

像所有的bean

庫類接口，具有服務

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

庫類的實現具有每個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(); 
     } 
    } 

}

，我得到什麼錯誤。

主這是不允許創建，因爲它得到空指針，但我不知道在這裏。

，我會很高興，如果u能幫助:)

我有四個實體。第一個是

@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; 
    } 

}

實體不是問題我仍然在發佈它。我有三個實體。 – 2014-09-06 10:02:29

你在其他地方有問題，你發佈的內容是無關緊要的。 – 2014-09-06 11:47:46

我認爲這個問題是在這裏，在AutherMasterTable（和其他實體類似的地方）：

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

對於一個一對多的加入，在JoinColumn annotation提到的連接列在其他表。它不涉及本表中的一列。此外，Set不能是標識符。

嘗試使用兩個字段代替：

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

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

注意，我們不是在同一個表定義兩次相同的列：上述的auid第一提及指的是列在tbl_authermaster和第二一指auid專欄tbl_bookmaster。

儘管你的錯誤，Hibernate不應該拋出一個NullPointerException在你身上。這是Hibernate中的一個錯誤。

讓我試試。 – 2014-09-08 08:27:08

我現在得到這個錯誤引起：org.hibernate.HibernateException：當'hibernate.dialect'未設置時連接不能爲空 – 2014-09-08 08:45:11

是它的真實和我已經解決的其他事情。 – 2014-09-08 09:49:26

閱讀堆棧跟蹤，你知道在哪裏：

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

你應該在調試與在該行斷點運行，但我認爲這基本上意味着你有一個錯誤您的實體，您的映射或它所運行的數據庫上。如果可以的話，你應該用Hibernate生成模式，然後你應該比較你的目標模式和生成的schema =>之間的差異，它會打印映射錯誤。

您的OneToMany和ManyToOne上也沒有mappedBy。你應該首先檢查（不是沒有錯誤，但如果數據庫模式與Hibernate預期模式不同步，它可能會成爲問題）。
