@@SeleniumExpress Using Constructor Mapping You can define a constructor in the DTO that takes an entity object as a parameter. This reduces the amount of boilerplate code. Example: ResponseDTO with Constructor: java Copy code public class EmployeeResponseDTO { private Long id; private String name; public EmployeeResponseDTO(Employee employee) { this.id = employee.getId(); this.name = employee.getName(); } // Getters } Usage: Employee employee = employeeRepository.findById(1L).orElseThrow(); EmployeeResponseDTO dto = new EmployeeResponseDTO(employee);
Thank you abhilash....! . I haven't seen this kind of clean and good content presentation anywhere. It was a great learning experience. Thank you once again and keep it up.
Hi Abhilash, kudos for providing this kind of content on RUclips. I request you to make a tutorial on junit/mocking when u get free time Thanks in advance 😊
your courses are good just a suggestion also include the error handling scenarios for the people who are new to this can get along with other things also.
Thanks Mani for the kind words. ❤️ You can choose any one of it for learning. Once you have a project assigned, the you can work on whatever that comes in your way.
In address response we dont have employee id and also in the repository query. When I use the same process, I am getting error like column for employee id not found. Unless I add the employee id in the native query and response class, the issue doesn't resolve. How to handle this ?
Thank you abhilash....! can you make video on merging 2 APi calls to 2 different micro-services (each having their own db copy) as one using say GrpahQl or CQRS in this series
I am so confused in databases. Before you said that in microservices architecture, each service has separate database. But here you make common database for address and employee service. Maybe you will tell us how to join tables, when services has own database?
Sir kindly explain, why are we manually creating database and table ? Is the objective of jpa repository to create the database and table automatically ?
Thank you for the great video! Is it possible to use h2-database with microservices (not in Production. Only during development). Assume that I load the database from a file and not from the memory. How am I going to set the relationship between Employee Service and Address Service (1 to 1) if they are actually a different application? Can I do something like this or it is impossible to do with an H2 database? Thank you in advance!
Hi Bro,It's a wonderful explanation..thank you very much for your support.but I have one doubt on importance of model mapper with and without.. please explain 😊
Hi Prasad, without a mapper it will be difficult to manually copy all your entity properties to dto/model properties, considering a scenario you got 30 properties inside your dto
Hi Bharath, then we got to manually map using another overloaded map method. There are different patterns matches that model mapper provides us. Please refer the model mapper doc. I will be creating few contents on model mapper and different mapping api in coming days.
It is not a good practice to return the actual entity to the user. This is why we use another class as a return type. For instance, assume we have an entity with 30 properties and we want to return to the user only some of them. We will have to create another class, in which we will map the values (only the properties we want to return to the user) from the entity to the response class and return the response class back to the user.
when iam going to practice same things in my sts, i am getting hibernate package as jarkata.persistence but for you javax.persistence, how you are getting that? can you please respond?

Pinned this comment. If anyone is reading this, here is another way how you could copy properties. It's another go to approach.
@@SeleniumExpress Using Constructor Mapping
You can define a constructor in the DTO that takes an entity object as a parameter. This reduces the amount of boilerplate code.
Example:
ResponseDTO with Constructor:
java
Copy code
public class EmployeeResponseDTO {
private Long id;
private String name;
public EmployeeResponseDTO(Employee employee) {
this.id = employee.getId();
this.name = employee.getName();
}
// Getters
}
Usage:
Employee employee = employeeRepository.findById(1L).orElseThrow();
EmployeeResponseDTO dto = new EmployeeResponseDTO(employee);
The most underrated channel sir, I really wish your channel grow faster and faster. It should be reaching more than a half million now already.
As a beginner, the way you teaching is best and easiest way for me to understand the microservices. Thank you so much for this.
Thank you abhilash....! . I haven't seen this kind of clean and good content presentation anywhere. It was a great learning experience. Thank you once again and keep it up.
Marvelous way of teaching 👍
Please start series of solving hackers ranking questions :)
Eagerly waiting for micro services series thanks 🙏 bro. This complete series is on RUclips
Thanks sir for the videos sir. Please release the videos regularly so that we can enhance our skill
4.:52 thank god she asked that question, I was having the same doubt as well.
Hi Abhilash, kudos for providing this kind of content on RUclips.
I request you to make a tutorial on junit/mocking when u get free time
Thanks in advance 😊
This channel must and should grow more, I request you everyone please share Abhilash videos.
Most waiting video 😍😍
A great explanation. Really helpful.
There is a implicit class called BeanUtils provided by spring as well to map property from entity to models.
your courses are good just a suggestion also include the error handling scenarios for the people who are new to this can get along with other things also.
Love your videos ❤️ eagerly waiting.
I have a doubt, which frontend framework goes good with springboot(react or angular)
Thanks Mani for the kind words. ❤️

sir ur background music get me chill when my overloaded by ur lecture
Can you please make a video on geting a list of employees? using the spring boot 3 ListCrudRepository? thanks in advance
Just curious as to why @Data was not used and manually @Getter @setter were used in entity class .
Also, we can use MapStruct (which automates the process of creating a mapper to map data objects with model objects using annotation) .

Hello Sir,
In service package, I am getting error as non static method findById(ID) cannot be referenced from a static context.
How to fix it?
I dont know u created foreignkey employee_id to address table, when I linked that my application error.
java.sql.SQLException: Column 'employee_id' not found.
How to resolve this issue
Please start series of real time project with microservices.
Hi Pradeep, you can follow the current series. This will serve the needs
@@SeleniumExpress Thank you abhilash. I have followed all Spring, Spring MVC series and share it too with frnds. It was great learning experience.

Abilash your videos very use full for all.please try to upload the source code.
Really good content sir.Is there any paid course available for this!! I want to explore more on this.
how do you deploy both microservices at the same time?
your intro song BGM is very motivational
Hello Sir I just came across your channel. May I know if you are teaching Development. Sorry I am just confused by the channel name
could have added spring data jpa, instead of manually working on databases and tables.
Post video for spring boot with multiple data source using spring data JpaRepository
Why you didn't use @Repository annotation in Repository class or its optional to use ?
@Selenium Express - ?
yepp, it is optional
Thank you for your greate lessons. Are there any your paid courses on Udemy? Might I have the links? Thank you very much
EmployeesResponse class properties will be change in case how to map both employees entity and response class
Could you please include authentication and authorisation as well
Hi Dikshi.
Sure, It's on the way ! Alternatively you can refer my spring security sessions
Why I am getting column id not found after removing ea.id
Bro please have a series on React
Hi Abhilash I asked one query in the last video plz reply is this series free to access or it's paid???
Hi Rahul, The spring cloud foundation will be free. However this video's are from my paid series which has 200+ hours of contents.
PLEASE MAKE VIDEO ON JAVA CONCURRENCY AND NON BLOCKING IO
What if variables name in target class doesn’t match with request object?
Hi Bharath, then we got to manually map using another overloaded map method.
There are different patterns matches that model mapper provides us. Please refer the model mapper doc.

Hi Abhilash when will we expect Next video for this series
This Saturday!
@@SeleniumExpress thanks
Why video quality is unavailable for this video😢
I think you can use IntelliJ and please white background with big font
Hi Pradeep, this series is already recorded. I will keep your suggestion in mind during my upcoming recordings.
@@SeleniumExpress are you building full-fledged microservices on youtube if yes, please include kafka
can u gives the source code of this lecture
