I am trying to delete an entity on a page via a delete link

  • 0

I am trying to delete an entity on a page via a delete link (a href) or delete button (form). I am using delete button since a link calls for a “GET” instead of a “POST”

This is the JSP code which intends on doing that:

<td><form:form method="DELETE" action="/client/invoices/${invoice.id}"><input type="submit" value="delete"></form:form></td>

The resulting html is this:

<td><form id="command" action="/client/invoices/9" method="post"><input type="hidden" name="_method" value="DELETE"/><input type="submit" value="delete"></form></td>

So, I’m pretty happy. It has _method which indicates that it is a DELETE action. Here is my controller code:

@RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
public String delete(@PathVariable("id") Long id, @RequestParam(value = "page", required = false) Integer page, @RequestParam(value = "size", required = false) Integer size, Model uiModel) {
        invoiceServiceHibernate.removeInvoice(id);
        return "redirect:/invoices";
}

So, what happens is that this method is not called. I have another method which does a POST to create an invoice and clicking the delete button instead created an invoice. My guess is that the controller looks at the servlet as a POST request and uses the first method which handles a POST request which in this case is to create a new invoice.

I try to make this “RESTful” so I want this to be /invoice/id and using POST, PUT, DELETE, GET but I am not sure how to code that in the controller using Spring MVC.

I am able to get this to work by appending “verbs” such as /invoices/id/delete and setting up the controller as

@RequestMapping(value = "/{id}/delete", method = RequestMethod.POST)

Note, the RequestMethod.POST but since the map values explicitly have /id/delete, it does not use the default POST which is mapped to /invoices and /invoices/id.

I hope I am clear. If anyone have any suggestions or sample code (strongly preffered), I would appreciate it. I’ve read these SO links for references:

    Did you set the HiddenHttpMethodFilter in your web.xml? That filter converts posted method parameters into HTTP methods and allows support for method conversion in the Spring MVC form tags.

    <filter>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <servlet-name>servletName</servlet-name>
</filter-mapping>
