For those who're getting nullPointerException and null values in database despite successful POST request, it can be sorted simply by replacing @Data annotation from model class with usual getters, setters.
I am a big fan of videos uploaded by Ramesh fadatare, his approach in explanation with lots of patience, consistency in explanation, perseverance till he reaches the last bit of the API. Thank you sir! You are a blessing to the Java Development world.
Every line was point to point . One who knows basics of java can easily understand through this video. Thanks, very useful. I tried to post and get data but it's doesn't work. after debugging I realized that the Lombok doesn't provide a getter and setter for the class. when I added it manually (get, set) everything works well!
been through countless udemy videos. Stopped learning spring boot as I felt it is way more complicated than nodejs backend dev, but this video is an absolute charm! Worked like magic. Second day and I am creating api's already!
bro I'm just starting out with Java Backend, will it be fine if I directly start with microservices and springboot. I've already strong knowledge of Java.
Thanks, very useful. I tried to post and get data but it's doesn't work. after debugging I realized that the Lombok doesn't provide a getter and setter for the class. when I added it manually (get, set) everything works well!
Lombok does provide getters and setters. I was facing the same issue with intellij IDE. I had to enable 'Annotations preprocessing' and also install Lombok plugin in order to access the getters and setters during compile time. Hope this helps if you are using intellij
Even I faced the issue with Lombok. Then I added getter , setters to java code by right click->generate getters and setters, Also to be able to debug I modified the header in postman to content-type:application/json/ One of them helped to create and save records to database
highly resourceful and knowledgeable, it definitely comes in handy to start a new spring boot application with good project structure and hibernate JPA
@Data annotation should work as a replacement for generating all the getters and setters. But for me the annotation is not working. I had to generate all the getters and setters manually. Otherwise whenever I am hitting the url with the json data no data is coming in to the controller.
When i had run the application and when i had inserted the values into database through post method in postman, I'm getting internal server error - 500. I can't get the values in database. Help me out
Sir please answer me : Does this project have Entity, Repository, Services, and Controller layers an at least one file in each one. The logic is up to you, but you need the have basic CRUD end points in your controller ?
Only One thing need to say. I Love your way of teaching :) Good 1.27 hours of learning from you. lastly you forgot to show the custom exception throw. I was waiting to see it.
Does anyone know why I got this error for the POST API? "not-null property references a null or transient value : com.example.springbootdemo.model.Employee.firstName" . I don't how to debug it
I have the same issue, with fadi Mashan explanation, I understood that Lombok didn't work. So I just did Source -> Generate Getter & Setter and it works.
Thank you soo much it worked for me. I saw many videos but every time struck somewhere in the code with errors. I am soo happy now that it successfully executed.
Hi, i am getting the following error when i try to post the json to the save restAPi. please help org.hibernate.PropertyValueException: not-null property references a null or transient value : com.example.SpringAPI.SpringAPI.model.Employee.firstName

Hi Ramesh, Great going tutorial.... I have one question as for hibernate whenever we initiate any operation we need to create Session factory / session objects.. But here as we are using hibernate with spring boot why session factory is not created. Is it managed by spring boot internally and if it's not then could you please guide here... Thanks in advance Thanks

Such a nice video to learn and you have explained it very easy way too. But I faced one issue while following your steps and unable to fix it. In postman i am getting an unsupported media error. Even when i have selected JSON, even tried with content-type = application/json. I am using java 8 and the highest stable version of spring boot and mysql. if you can suggest me the fix, that will be very helpful. code I have copied from your git. so all are the same, except pom (versions)

Guys, let's use the latest version of Spring boot, hibernate, and MySQL database to build Rest web services. More free courses inline, stay tuned!.

Please can you do registration and login authentication with Android app using retrofit to send and receive http requests to spring boot backend?
Ok man, I am sorry. Now I have STS integrated with Eclipse and everything is workong just fine. Thx for tutorial Man!
