Getting UnsatisfiedServletRequestParameterException while trying to disable submit button using jquery

Question

I have single form with multiple submit buttons, each performs separate function like:

• Search
• Update
• Add
• Delete

All actions are POST, and use name attribute in button tag mapped to params in Controller side. Everything is working fine so far. Now I need to disable the click of button while form is getting submitted and on the server side db updates are completed and server reply back.

So using jquery I added below code and then it stopped working.

JS

$('form').submit(function(e) {
   $(this).find("button[type='submit']").attr('disabled',true);
});

HTML

<form id="formSecurity"
    th:action="@{/security}" th:object="${securityDTO}" method="POST">
    <div class="form-group col-md-6">
        <div class="input-group">
            <input class="form-control" type="text" th:field="*{secId}" id="secId" placeholder="Find by SecId..." />
            <div class="input-group-append">
                <button class="btn btn-primary" name="search" type="submit">Search</button>
            </div>
        </div>
        ...
    </div>
    ...
</form>

Controller

@PostMapping(value="/security", params={"search"})
    public String searchSecurity(final SecurityDTO securityDTO, final BindingResult result, Model model) {
    ...
}

@PostMapping(value="/security", params={"update"})
    public String searchSecurity(final SecurityDTO securityDTO, final BindingResult result, Model model) {
    ...
}

@PostMapping(value="/security", params={"addRow"})
    public String searchSecurity(final SecurityDTO securityDTO, final BindingResult result, Model model) {
    ...
}

@PostMapping(value="/security", params={"removeRow"})
    public String searchSecurity(final SecurityDTO securityDTO, final BindingResult result, Model model) {
    ...
}

But now looks like name params is not getting submitted. And I am getting below error:

WARN 16660 --- [nio-8989-exec-8] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.bind.UnsatisfiedServletRequestParameterException: Parameter conditions "search" OR "update" OR "addRow" OR "removeRow" not met for actual request parameters: secId={1234}]
