No operations defined in spec!! and 404 error in postman. The spring boot don't show any error from my code. yet i can't establish the connection

This is a simple code that i got from youtube for practice. well i did the code correcly but i cant get the explicit mapping correclty, that what the 404 error in the postman says.
I don't know if its my Spring boot app problem or the code error. please have a look at this , Since spring boot is not giving a proper answer.

When I run this application everything looks fine but I can't see the POST/PUT/or DELETE. I try to many things I find from Internet but it doesn't work. I new on this topic. I actually want to wrote null inputs and get exceptions for exception handling.

So your Docket Configuration has specified a regex pattern for product
#Bean
public Docket productApi() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.basePackage("example.com"))
.paths(regex("/product.*"))
.build()
.apiInfo(metaData());
}
But your controllers don't have any APIs with /product.
Thus you're not able to see APIs in swagger documentation.
Try with below configuration and see if it shows you all endpoints and then start working around regex configurations.
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
Above configuration matches all the API paths in your web application basically anywhere.
You can access your APIs at
Change the APPLICATION_PORT and CONTEXT-PATH
http://localhost:{{APPLICATION_PORT}}/{{CONTEXT-PATH}}/swagger-ui.html

Field book in com.example.BookProject.Servies.BookServies required a bean named 'book' that could not be found

I have this Problem with Spring-boot
When Run the Server cannot run

Description:
Field book in com.example.BookProject.Servies.BookServies required a bean named 'book' that could not be found.
The injection point has the following annotations:

Action:
Consider defining a bean named 'book' in your configuration.

The issue is due to dependency conflict, spring-boot-starter-data-jpa dependency is enough, because hibernate-core 5.X.X Final version is included.
From the above image I hope you understood the issue,
Solution:
Removed unwanted dependencies and resolved the conflict
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>

<scope>test</scope>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
</dependencies>
After removed the unwanted dependencies application is up,

Why #Valid do not works

I am taking an online course and the instructor placed two notes to validate fields in my category object. An #Notnull annotation in the name attribute and #Valid in the controller, in his video the error http response changes from 500 to 400, as it is validating the attributes. Before he put the validation back, he returned 500. Mine keeps returning 500. In other words, the annotations #Valid and #Notnull do not seem to have any effect, does anyone know why?
Here is my code:

}
public void setCodigo(Long codigo) {
this.id = codigo;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
}

Some annotations are part of JSR 380 & some are JSR 303.
so try to include below dependency that supports most of the javax validations.
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>6.1.5.Final</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
<version>2.3.1.RELEASE</version>
</dependency>

please check for maven dependencies if not their add them for using #Valid in you project.
you can add them from :
https://mvnrepository.com/artifact
https://mvnrepository.com/artifact/org.hibernate.validator/hibernate-validator
https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-validation
https://mvnrepository.com/artifact/javax.validation/validation-api
