Thymeleaf-将变量传递给控制器

Question

I have a problem with Spring and Thymeleaf.

I have a controller:

@RequestMapping(value = "/add")
public String addPage(@PathVariable("id") String id, Model model) {
    InvoiceData invoiceData = new InvoiceData();
    model.addAttribute("contractorid", id);
    model.addAttribute("invoicedata", invoiceData);
    return "add";
}

And I have an URI:

<li class="menu"><a th:href="@{/add/{id}(id=${contractor.id})}">Add invoice</a>

and of course, I have this add.html document containing a form to fill and save data to ContractorData .

But when I click the link, I get:

There was an unexpected error (type=Not Found, status=404).
No message available

And the URL in the browser looks like this:

http://localhost:8080/add/5c9e31b05b9b380a6b08dc94

So it is completely basing on the basic URI

How do I modify the URI or my code so I can pass the contractor.id to the /add controller and put it into Model so it will be available for me to use in add.html?

Answer 1

It should help, i think.

@RequestMapping(value = "/add/{id}")
public String addPage(@PathVariable("id") String id, Model model) {
    InvoiceData invoiceData = new InvoiceData();
    model.addAttribute("contractorid", id);
    model.addAttribute("invoicedata", invoiceData);
    return "add";
}
