Mapping buttons to controllers in Spring Boot

I have these buttons:

<form>
    <input type="submit" class="button" name="Test 1" value="Test 1">
    <input type="submit" class="button" name="Test 2" value="Test 2">
    <input type="submit" class="button" name="Test 3" value="Test 3">
    <input type="submit" class="button" name="Test 4" value="Test 4">
    <input type="submit" class="button" name="Test 5" value="Test 5">
</form>

I want each button to map to a separate controller like so:

@GetMapping("/panels")
public void test1() {
    System.out.println("TEST 1!");
}

@GetMapping("/panels")
public void test2() {
    System.out.println("TEST 2!");
}

@GetMapping("/panels")
public void test3() {
    System.out.println("TEST 3!");
}

@GetMapping("/panels")
public void test4() {
    System.out.println("TEST 4!");
}

@GetMapping("/panels")
public void test5() {
    System.out.println("TEST 5!");
}

How do I do that? I haven’t found an explanation that works and/or that I understand. (I’m very new to Spring Boot.)

>Solution :

You can try something like the following

  <form>
     <button type="submit" formaction="http://localhost:8080/all-panels/panel1">Test1</button>
     <button type="submit" formaction="http://localhost:8080/all-panels/panel2">Test2</button>
     <button type="submit" formaction="http://localhost:8080/all-panels/panel3">Test3</button>
     <button type="submit" formaction="http://localhost:8080/all-panels/panel4">Test4</button>
     <button type="submit" formaction="http://localhost:8080/all-panels/panel5">Test5</button>
  </form>

And then use a controller like

@RestController
@RequestMapping("all-panels")
public class PanelsController {

   @GetMapping("/panel1")
   public void test1() {
      System.out.println("TEST 1!");
   }

   @GetMapping("/panel2")
   public void test2() {
      System.out.println("TEST 2!");
   }

   @GetMapping("/panel3")
   public void test3() {
      System.out.println("TEST 3!");
   }

   @GetMapping("/panel4")
   public void test4() {
      System.out.println("TEST 4!");
   }

   @GetMapping("/panel5")
   public void test5() {
      System.out.println("TEST 5!");
   }

}

Keep in mind that while you develop your application you normally have both backend and frontend in your machine so the following will work formaction="http://localhost:8080/all-panels/panel1"

When however deployed for production the frontend will normally be the client sitting in his own computer. So then for this to work you will have to do

formaction="{backend-url}:{backend-port}/all-panels/panel1"

where {backend-url} is the domain where this is deployed and {backend-port} the port that your backend is listening to.
