在Spring控制器中发送表单数据而不使用注释

我想在控制器中发送表单输入数据，而不使用注释

在这段代码中，我试图从jsp文件中获取

employeeNo

，

empName

，

deptNo

，我在jsp文件中使用了Spring

，

标记，但当我试图获取值时，它没有获取值，并引发异常：

java.lang.IllegalStateException: Neither BindingResult nor plain target object 
for bean name 'command' available as request attribute 

我的控制器：

    private EmployeeServiceImpl employeeServiceImpl;

    public void setEmployeeServiceImpl(EmployeeServiceImpl employeeServiceImpl) {
        this.employeeServiceImpl = employeeServiceImpl;
    }

    public ModelAndView searchByEmpNo(HttpServletRequest request,
            HttpServletResponse response) throws Exception {

例如按员工姓名搜索

匹配名称以字符S开头的所有员工

搜索控制器
dberrorView
编号

错误的原因是请求中没有可将字段绑定到的对象。因此，在返回此视图时，需要向jsp传递一个对象

在方法中，返回上述jsp和表单 这样做

我没有在您的代码中看到任何注释。返回jsp文件的代码在哪里？@AvinashT。我不想要用过的注释，所以没有注释，我正在尝试这样做，就像我在这里粘贴的一样，现在请告诉我如何在我的控制器中检索请求的数据，因为在jsp中我使用了spring表单标记，我不想要用过的注释controller@shazinltc在xml文件中，你可以从他们的“我导航到我的视图”（jsp）中找到我的jsp@亨利·查尔斯：那是员工搜索页面？

public ModelAndView yourMethodForView(){
//Assuming Employee object has employeeNo and empName
Employee emp = new Employee();
//your code
return new ModelAndView("yourFormJspName","employee",emp);
}
