Issue
I am not sure what is wrong with my codes. I was trying to learn Spring Boot. But I am not able to run the application as i get the below error
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'passwcController' defined in file [D:\ProjStpring+Java\passwcontroller\target\classes\com\projects\passwcontroller\web\PasswcController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'passwcRepository' defined in com.projects.passwcontroller.data.PasswcRepository defined in @EnableJpaRepositories declared on JpaRepositoriesRegistrar.EnableJpaRepositoriesConfiguration: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not a managed type: class com.projects.passwcontroller.Passwc

Solution
I think you might need to add a dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>2.7.2</version>
</dependency>
This also means you might be missing a couple of JPA annotations in Passwc. Take a look at https://www.baeldung.com/the-persistence-layer-with-spring-data-jpa.
