Try catch not working Laravel raw queries | How to properly catch PHP exceptions (Laravel 5.X) | Why try catch not work in Laravel

Make sure you're using your namespaces properly. If you use a class without providing its namespace, PHP looks for the class in the current namespace. Exception class exists in global namespace, so if you do that try/catch in some namespaced code, e.g. your controller or model, you'll need to do catch(\Exception $e) to catch all your exceptions:  

try {
  //code causing exception to be thrown
}
catch(\Exception $e) {
  //exception handling
}

If you do it like this there is no way to miss any exceptions. Otherwise if you get an exception in a controller code that is stored in App\Http\Controllers, your catch will wait for App\Http\Controllers\Exception object to be thrown.

Simple try & catch TagLib | Tag Library for Grails GSP views

First you have to create a TagLib as below:

With following contents:

package com.pkm.taglib

class TryCatchTagLib {
    static namespace = "ui"

    def Try = { attrs, body ->
        try {
            out << body()
            request.exception = null
        }
        catch (Throwable e) {
            request.exception = e
        }
    }

    def Catch = { attrs, body ->
        if (request.exception) {
            out << body(exception: request.exception)
            request.exception = null
        }
    }
}

And use of try-catch as below:

<ui:try>
    SOME WORK I AM TRYING
</ui:try>
<ui:catch>
    GOT EXCEPTION=${exception}
</ui:catch>
