Question

My project based on spring boot,Thymeleaf,mysql,html and Jquery.

My scenario is to Get the List iterate and show the d

Answer 1

You used the form at the top of your html page:

<form method="post" th:object="${entSetCharges}" th:action="@{/updatesetcharges}">

The th:field="*{chargesName} is bound to the object/bean inside your th:object="${entSetCharges}. Meaning that you are searching for a chargesName field inside your entSetCharges object which does not exist or is null.

Solution:

• Maybe change your th:field="*{chargesName}" to ${savedcharges.chargesName} expression to access your object's field.

• Try adding respondResult.addObject("entSetCharges",new EntSetCharges()); above your return line. Your view doesn't automatically create this object for you.

Answer 2

I init the entity object like respondResult.addObject("entSetCharges",new EntSetCharges());

@GetMapping(value="/setchargeslist")
    public ModelAndView doGetSetchargesList()
    {
        List<EntSetCharges> listCharges = new ArrayList<>();
        ModelAndView respondResult = new ModelAndView("SetCharges");
        try {
            /*Get the set charges list*/
            listCharges = serSetCharges.doGetSetChargesList();
            if(listCharges!=null)
            {
            respondResult.addObject("savedchargeslist",listCharges);
            respondResult.addObject("entSetCharges",new EntSetCharges());
            }
            else
            {
                respondResult.addObject("savedchargeslist",new ArrayList<>());
            }

        } catch (Exception e) {
            // TODO: handle exception
        }
        return respondResult;
    }
