I am Beginner in Spring-boot, when I try to run the Spring-boot Application then I am facing this problem when I try to run the Spring-Boot Application.

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type com. JPA. test. User Repository available
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:340)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:331)
    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1148)
    at com. JPA. test. Test Application. main(TestApplication.java:17)

I am Expecting that the data will be properly saved in the data base.

Try adding those annotations to your program:

@Configuration
@EnableAutoConfiguration
@ComponentScan
@EntityScan("com.jpa.test")
@EnableJpaRepositories("com.jpa.test")

As far as I can tell the problem here is that you need to run your code inside the Spring Boot context. Usually the SpringApplication.run does not return until the webserver of spring exits. You can execute code at the start of a spring boot program by using a CommandLineRunner:

@Component
class Runner implements CommandLineRunner {

    private final UserRepository userRepository;

    // Use Spring dependency injection
    public Runner(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    @Override
    public void run(String... args) throws Exception {
        User user = new User();
        user.setName("XYZ");
        user.setStatus("Active");
        user.setCity("OOPS");
        
        User save = userRepository.save(user);
        System.out.println(save);
    }
}
