Giving  ahead of any bash script command will trigger failure if any command fails. 

It's like having a trap handler.

Java learnings - Handling bad request

Consider you have a records array 

and 

each record has to be validated independently in your service 

And

In json response , you want to respond status of each record.

This can be achieved by Overriding above function in your global exception hander. 

Sample use case :

{ 

'Records" : [

       {

           "name" : "name",

           "Id": 123

        },

      {

           "name" : "name2",

           "Id": 124

        },

    {

           "name" : "name",

           "Id": 123x

        },

}

And 

You wrote Jason property validation on "Id" where it can't accept non integer.

Then you can annotate

--------

@jsonproperty("id')

@PositiveOrZero(message = "incorrect Id")

Private Integer Id:

--------

Because of above annotation, framework will raise a exception which will call the abobe overrided funcion. Here we will be able to do.

{ 

'Cause" : [

       {

           "Messsage" : "incorrect id",

           "Field": "records[2].I'd"

        },

     

}
