異常hibernate插入語句

謝謝。這是一個小項目。這是整個項目的代碼。代碼中發生的事情是，當下拉框加載實體類中ownerName的值時，在任何成員被選中時從下拉列表中選擇一個信用限額，然後由jsp頁面上的輸入框指定信用限額。因此，沒有爲ownerName輸入信息，但只有信用限額是根據下拉框中所選的ownerName設置的。這是實體文件：異常hibernate插入語句

@Entity 
@Table(name = "accounts") 
public class CyclosUsers { 

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


    @Column(name = "owner_name") 
    private String ownerName; 

    @Column(name = "credit_limit") 
    private float creditLimit; 

    public CyclosUsers(){} 

    public CyclosUsers(String ownerName, float creditLimit) 
    { 
     super(); 
     //this.id = id; 
     this.ownerName = ownerName; 
     this.creditLimit = creditLimit; 
    } 

    public CyclosUsers(int id, String ownerName, float creditLimit) { 
     super(); 
     this.id = id; 
     this.ownerName = ownerName; 
     this.creditLimit = creditLimit; 
    } 

    public int getId() { 
     return id; 
    } 

    public void setId(int id) { 
     this.id = id; 
    } 

    public String getOwnerName() { 
     return ownerName; 
    } 

    public void setOwnerName(String ownerName) { 
     this.ownerName = ownerName; 
    } 

    public float getCreditLimit() { 
     return creditLimit; 
    } 

    public void setCreditLimit(float creditLimit) { 
     this.creditLimit = creditLimit; 
    } 

}

這是DAO implemetation文件：

@Repository 
public class CyclosUsersDaoImpl implements CyclosUsersDao { 

    @Autowired 
    private SessionFactory sessionFactory; 

    @Override 
    public void saveCyclosUsers(CyclosUsers cyclosUsers) { 
     sessionFactory.getCurrentSession().createSQLQuery("INSERT INTO credit_limit WHERE" +" " +"WEB-INF.views.Register.ownerName.selectedItem(" +"ownerName"); 
    } 

    @SuppressWarnings("unchecked") 
    @Override 
    public List<CyclosUsers> addToDropDown() { 
     return sessionFactory.getCurrentSession().createSQLQuery("SELECT owner_name FROM accounts").list(); 
    } 

    @SuppressWarnings("unchecked") 
    @Override 
    public List<CyclosUsers> CyclosUsersAndAccountDetails() { 
     return sessionFactory.getCurrentSession().createCriteria(CyclosUsers.class).list(); 
    } 

}

服務實現文件：

@Service 
public class CyclosUsersServiceImpl implements CyclosUsersService { 

    @Autowired 
    private CyclosUsersDao cyclosUsersDao; 

    @Override 
    @Transactional 
    public void saveCyclosUsers(CyclosUsers cyclosUsers) { 
     cyclosUsersDao.saveCyclosUsers(cyclosUsers); 
    } 

    @Override 
    @Transactional 
    public List<CyclosUsers> addToDropDown() { 
     return cyclosUsersDao.addToDropDown(); 
    } 

    @Override 
    @Transactional 
    public List<CyclosUsers> CyclosUsersAndAccountDetails() { 
     return cyclosUsersDao.CyclosUsersAndAccountDetails(); 
    } 

}

這是控制器文件：

@Controller 
public class CyclosUsersController { 

    @Autowired 
    private CyclosUsersService cyclosUsersService; 

    @RequestMapping("/register") 
    public ModelAndView displayOverdraftForm(@ModelAttribute("cyclosUsers") CyclosUsers cyclosUsers, BindingResult bindingResult) 
    { 
     Object addMembersListToDropdown = null; 
     ArrayList<Object> membersListing = new ArrayList<>(); 
     membersListing.add(cyclosUsersService.addToDropDown()); 

     for(Object listingMembers : membersListing) 
     { 
      addMembersListToDropdown = listingMembers; 
     } 
     System.out.println(addMembersListToDropdown); 
     return new ModelAndView("Register", "addMembersListToDropdown", addMembersListToDropdown); 
    } 

    @RequestMapping("/saveCyclosUsers") 
    public ModelAndView saveCyclosUsersCredentials(@ModelAttribute("cyclosUsers") CyclosUsers cyclosUsers, BindingResult bindingResult) 
    { 
     cyclosUsersService.saveCyclosUsers(cyclosUsers); 
     System.out.println("Cyclos Users List:"); 
     return new ModelAndView("redirect:cyclosUsersList.html"); 
    } 

    @RequestMapping("/cyclosUsersList") 
    public ModelAndView listCyclosUsersOverdraftDetails() 
    { 
     @SuppressWarnings("unused") 
     CyclosUsers cyclosUsers = new CyclosUsers(); 
     Map<String, Object> model = new HashMap<String, Object>(); 
     model.put("cyclosUsers", cyclosUsersService.CyclosUsersAndAccountDetails()); 
     return new ModelAndView("cyclosUsersDetails", model); 
    } 
}

這是JSP頁面：

根據堆棧跟蹤，錯誤來自'CyclosUsersDaoImpl'類，當它嘗試從會話列表中時。你可以從'CyclosUsersDaoImpl'類發佈'CyclosUsersAndAccountDetails'方法的代碼嗎？ –

設置爲空的屬性，

@Column(name = "credit_limit", nullable=true) //nullable set true 
private Float creditLimit; //Float instead of float

，並使用非原始包裝類型浮動，而不是浮動（這是一個基本類型）。

謝謝。你的建議解決了60％的問題。雖然錯誤消失，但插入不成立。方案是這樣的：下拉框由數據庫中帳戶表中列的ownerName值填充。 ownerName是已存在於db中的用戶，因此不會爲其創建新記錄。簡單的做法是爲ownerName插入一個creditLimit，所以當在下拉框中選擇這些ownerName時，將爲其設置creditLimit。 – kehinde

你是否獲得了控制器中所選ownerName的creditLimit值..只有這個creditLimit是空值你得到一個錯誤..有點jQuery或JavaScript，並在輸入框中設置creditLimit值爲相應的ownerName從下拉框中選擇..這種方式當你提交表格時，你可以將此參數發送給控制器，然後設置信用額度值。根據在下拉列表中選擇的ownerName以編程方式執行此操作，或允許用戶手動輸入值.. – Lucky

堆棧跟蹤是相當清楚的：你不給你CyclosUsers的creditLimit屬性賦值類，這是一個原始的，所以它不能是null。

此外，我不認爲你的查詢有正確的語法;而不是：

INSERT INTO credit_limit WHERE

嘗試類似：

INSERT INTO table_name (column_1, column_2) VALUES (value_1, value_2);

（確切的語法可能取決於你使用的數據庫引擎而異）。

如果您發佈了CyclosUsers類的代碼，我可能會幫助更多。在@Column批註爲true
