Incredibly Amazing Work. No doubt in that. Quick correction tip: In the screenshot at 1:44:20 , The parse method return type should be Amount

can't we use tostring() method in phone class to get output, here in the above the print method in formatter class is being called

Hi Abhilash, Its a great initiative by you to share your knowledge with us. I am following your spring videos to groom my skills. I have a request to make, can you please make a series on spring boot also , it will be a great help to us.

[@sachinaherrao2823]

Hi Abhilash, thank you for the Spring MVC series. It is really helping me to learn these things qucikly and implement these things in my project. Since we already have 9 tutorials. I would like to know how many more tutorials will be there to complete Spring MVC intermediate?

hi , i have followed the same steps to configure formatter class, but my parse method is not invoking ?

[@tuberhsieh34]

When email textbox and phone number textbox are blank, communication.email is filld as "" (empty string) by Spring, but communication.phone is null and Phone formatter was not even called (I have tested that Phone formatter was called if phone number textbox is not blank). Why email is treated as empty string by Spring, but phone number was not passed as empty string into my Phone formatter? Looks like if a query parameter's value is empty string, Spring won't call the formatter to do conversion !?

[@sayantanghosh8245]

Very happy.... Long awaited ❤️

[@shubhi2648]

thanks for explaination sir.. however have one question: at time 01:03:15 when we are printing phone number in registerationSuccess page. there toString of Phone class is coming into picture and phone number is correctly displayed.. Why same thing is not happening in Register Page later (when we felt the need of using print method.. )

[@puksapple5104]

we r printing the string representatoin of object using toString() ..and what u r talking about register page plz clarify more..

[@tuberhsieh34]

About register page, it's using Spring form tags, so there is data binding between form tags and model attribute(i.e.UserRegistrationDTO). When form tag textbox phone is binded to UserRegistrationDTO.communication.phone, Spring uses formatter's parse() function to convert from String to Phone object; when Spring wants to bind UserRegistrationDTO.communication.phone to form tag to show text, Spring uses the reverse method formatter's print() function to convert from Phone object back to String. Inside registration-success page, accessing ${userRegistrationDTO.communication.phone} represents object in it's string format (by toString() function). I think they are just two different mechanisms. Of course we can also use the ${......} to access model attributes's property in register page.

Salute your courage, enve in lock down period you are work so hard from home town. Could we know your home town please.

[@manasanayak28]

Hi how exactly spring came to know that it has to execute formatter class for phone number field only? And also if there are multiple formatter classes , how spring will come to know what class to invoke?

[@Banaras_08]

This tutorial for beginners is very useful like me

[@IgorTodorovic1987]

Default value of String is null, but we do not get an exception so now I'am confused. Can somebody explain that to me.

[@tuberhsieh34]

Because we write UserRegistrationDTO as a function argument of showRegistrationPage(), Spring will try to bind the query parameters in URL to UserRegistrationDTO object. There is no query parameters while accessing URL "/register", so Spring has nothing to bind and all fields of UserRegistrationDTO keeps their default values(reference type is null). So at 1:14:23, when trying to access method/property of a null object, exception happened. Because we write UserRegistrationDTO as a function argument of processUserReg(), Spring will also try to bind the query parameters in URL to UserRegistrationDTO. There are query parameters while accessing URL "/register-success". For example, if textbox of user name is blank, then URL will be "/register-success?userName=&password=......", so there are query parameters for Spring to bind. So userName field of UserRegistrationDTO object becomes empty string because query parameter userName's value is empty string. Try to debug and set break points inside both showRegistrationPage() and processUserReg(), then watch the value of fields of UserRegistrationDTO object to see the difference.

[@ankitsethia6534]

Sir if we store phone number as a String variable then what is the problem? Is it mandatory to use org.springframework.format.Formatter parse and print method? Please reply Sir.

[@SeleniumExpress]

Hi Ankit, No it is not mandatory. If it string type, you wont be needing a formatter. However, most of the time we have to deal with complex object type in real time.

Hello Abhishek, Is it possible to add hibernate validator for the phone and put some regular expression so that user is forced to enter the phone number in a prescribed format(eg: 91-1234567890) checking if anything before the hyphen is number before hyphen and after hyphen it should be 10 digits. Could you please explain how we can enforce this one. Again Thank you so much for the videos. Appreciate all the work you're doing.

I have just added one "else if" to solve Assignment #1 if (index == -1) { // if the "-" is not found, then add 91 as the default country code phone.setCountryCode("91"); phone.setUserNumber(phoneNumberArray[0]); } else if (index == 0) { phone.setCountryCode("91" + ""); phone.setUserNumber(phoneNumberArray[1]); } else { // Extract the countryCode and set it to the phone class countryCode property phone.setCountryCode(phoneNumberArray[0]); phone.setUserNumber(phoneNumberArray[1]); }

for assignment #1 instead of changing whole logic we can solve the issue by adding just one else if statement if(index==-1) { phone.setCountrycode("91"); phone.setUsernumber(phonenum[0]); } else if(index==0) { phone.setCountrycode("91"); phone.setUsernumber(phonenum[1]); } else { phone.setCountrycode(phonenum[0]); phone.setUsernumber(phonenum[1]); }
