@RestController
public class CustomizedResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(HttpRequestMethodNotSupportedException.class)
    public final ResponseEntity httpRequestMethodNotSupportedException(Exception ex, WebRequest request) {

How to handle an exception is thrown by Select method of ObjectDatasource?

wish helps you Look at the eventargs on the ObjectDataSource. There should be an e.Exception & e.Results that you can query for the success/error of your select.
protected void MyOds_Selected (object sender, ObjectDataSourceStatusEventArgs e)
{
    if (e.Exception != null)
    {
        // handle exception here.
...
    //tell the ObjectDatasource that the exception is handled
    //and don't rethrow it.
    e.ExceptionHandled = true;

    }
}

this will help I've formatted your code like this and you can set your logic when you want to throw exception
<?php 
class AllAccidents 
{
  public static function check() {
    try {
        self::checkNum(2);

    }catch (Exception $e){
        echo $e->getMessage();
    }
  }

 public static function checkNum($number) {
    if($number>1) {
      throw new Exception("Value must be 1 or below");
    }
  return true;
 }
}

class Test 
{
   public function go(){
     try{
        AllAccidents::check();
     } catch (Exception $e){

     }
   }
}

$obj = new Test();
$obj->go();
?>

An elegant way to ignore any errors thrown by a method

Hope this helps I'm removing a temporary file with NSFileManager like this: , If you don't care about success or not then you can call
let fm = NSFileManager.defaultManager()
_ = try? fm.removeItemAtURL(fileURL)
if (try? fm.removeItemAtURL(fileURL)) == nil {
    print("failed")
}
let fileURL = URL(fileURLWithPath: "/path/to/file")
let fm = FileManager.default
try? fm.removeItem(at: fileURL)

I think the issue was by ths following , Read the difference between checked exceptions (mandatory to be handled), and non-checked exceptions (optional to be handled) in Java.
