Hibernate批量更新失败

Question

我已经这样做了几天，没有解决方案。我祈祷有人给出了足够的答案来解决这个问题。它确实是一项成就。 我想要实现的目标 界面上只有三（3）个控件 - 下拉列表，输入和提交按钮。下拉列表从数据库中的表中的列（ownerName）获取其值。要从界面执行事务，从下拉列表中选择一个值，将值输入到要提交到creditLimit列的输入框（文本框）中，并单击提交按钮。要更新的数据库中的表具有以下列：ownerName，crediLimit和id等。不会插入新记录，而只是通过从下拉列表中为所选ownerName指定值作为creditLimit来更新现有记录。 这是JSP代码：

<tr>
                    <td><form:label path="ownerName">Select Overdraft User:</form:label></td>
                    <td><form:select path="ownerName" name = "ownerName" items = "${addMembersListToDropdown}"></form:select></td>
                </tr>
                <tr>
                    <td><form:label path="cyclosUsersCreditLimit" name = "cyclosUsersCreditLimit">Enter an Amount:</form:label></td>
                    <td><form:input path="cyclosUsersCreditLimit" name = "cyclosUsersCreditLimit"/></td>
                </tr>
                <tr><td></td><td><input type = "submit" value = "Grant Overdraft"></td></tr>

这是DAO代码： 此代码将数据库中表的ownerName列添加到下拉控件 - 它的工作

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

此代码用于更新数据库中表中的ownerName记录 - 无效。

@Override
    public void updateCyclosUsers(CyclosUsers cyclosUsers) {
        sessionFactory.getCurrentSession().update(cyclosUsers);
    }

这是Controller代码 这段代码似乎不起作用。它假设执行更新声明。

@RequestMapping("/updateCyclosUsers")
    public ModelAndView updateCyclosUsers(@ModelAttribute CyclosUsers cyclosUsers, BindingResult result, HttpServletRequest request)
    {
        cyclosUsersService.updateCyclosUsers(cyclosUsers);
        System.out.println("Save User Data");
        return new ModelAndView("redirect:cyclosUsersList.html");
    }

当我运行页面时，一切正常，只有当我尝试执行错误显示的事务时才会出现问题。表示表中没有更新记录，此错误：

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1; nested exception is org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
