Spring MVC - 如何使用DAO + Service

Question

我在jsp中创建了可编辑的表，它从数据库中显示整个表，并且在我得到的最后一列旁边＆＃34;编辑＆＃34;更新特定行的按钮。问题是点击＆＃34;编辑＆＃34;编辑的行不想更新，任何错误都出现在控制台中。我做错了什么？

控制器：

@RequestMapping(value="/employeelist.html", method = RequestMethod.POST)
    public ModelAndView editOrDeleteEmployee(Model model, @ModelAttribute("employee") Employee employee, @RequestParam String editEmployee) throws SQLException{

        setAppContext();        

        clinicService.updateEmployee(employee, "2");

        List<Employee> employees = clinicService.getAllEmployees(); 
        model.addAttribute("employees", employees);

        ModelAndView mstaff = new ModelAndView("EmployeeList");
        return mstaff;

    }

DAO：

public void updateEmployee(Employee employee, String id) {
    String query = "update virtualclinic.employee SET name=?, lastname=?, gender=?,"
            + "position=?, salary=?, phonenumner=?, address=? WHERE idemployee=?";
    Connection con = null;
    PreparedStatement ps = null;
    try{
        con = dataSource.getConnection();
        ps = con.prepareStatement(query);
        ps.setString(1, employee.getName());
        ps.setString(2, employee.getLastName());
        ps.setString(3, employee.getGender());
        ps.setString(4, employee.getPosition());
        ps.setString(5, employee.getSalary());
        ps.setString(5, employee.getPhoneNumber());
        ps.setString(6, employee.getAddress());
        ps.setString(7, employee.getId());

        id = employee.getId();

        int out = ps.executeUpdate();



    }catch(SQLException e){
        e.printStackTrace();
    }

服务：

public void updateEmployee(Employee employee, String id) {
    ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext("clinicconfig.xml");
    employeeDAO = ctx.getBean("employeeDAO", EmployeeDAOImpl.class);

    employee.setName(employee.getName());
    employee.setLastName(employee.getLastName());
    employee.setGender(employee.getGender());
    employee.setPosition(employee.getPosition());
    employee.setSalary(employee.getSalary());
    employee.setPhoneNumber(employee.getPhoneNumber());
    employee.setAddress(employee.getAddress());
    employee.setId(employee.getId());

    id = employee.getId();

    employeeDAO.updateEmployee(employee, id);

}

JSP文件：

 <c:forEach items="${employees}" var="employee">
            <tr style="font-size: 10">
                <td>${employee.id}</td>
                <td><div contentEditable='true'>${employee.name}</div></td>
                <td><div contentEditable='true'>${employee.lastName}</div></td>
                <td><div contentEditable='true'>${employee.gender}</div></td>
                <td><div contentEditable='true'>${employee.position}</div></td>
                <td><div contentEditable='true'>${employee.salary}</div></td>
                <td><div contentEditable='true'>${employee.phoneNumber}</div></td>
                <td><div contentEditable='true'>${employee.address}</div></td>
                <td><form action="/VirtualClinic/employeelist.html?editEmployee=${employee.id}"  method="POST"><input type="submit" value="Edit"/></form></td>
            </tr>
            </c:forEach>
