SpringMVC с Ajax и Jquery

Question

Hi Everybody, 

Here I am using 
Java - 1.7, 
Tomcat Web Server 1.8 
Spring 4.x 
ajax 
Jquery "https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" 

My problem is when I am trying send values from ajax to spring controller I am getting one warning called "IOException" 

Saying that 

"org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver logException 
WARNING: Handler execution resulted in exception: Required String parameter 'deptId' is not present" 

Изначально мои данные отправляли к контроллеру, но тогда и только первым был печать остальными все были давать как неопределенные/нуль в, но я жесткие значениях коды в Ajax вызова и отправить весной контроллер, то его работает отлично

And my data is not being reached to Spring controller

Answer 1

Я нашел решение для вышеуказанного вопроса решение Я только изменил мой depts.jsp данных Ajax вызова: свойство, как показано ниже
данных: DEPTNAME: $('#deptName').val(),deptId:$('#deptId').val(),yarnCount:$('#yarnCount').val(),shiftNo:$('#shiftNo').val(),shiftInc: $('#shiftInc').val(),deptInc:$('#deptInc').val()}
