No qualified bean of type 'com.jpa.test.UserRepository' found exception occurred in the main thread

Question

I am a beginner in Spring-boot and I faced this issue when I tried to run a 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 want the data to be saved correctly in the database.

Main class code:

package com.jpa.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.context.ApplicationContext;


@SpringBootApplication(exclude={DataSourceAutoConfiguration.class})
public class TestApplication {

    public static void main(String[] args) {
        
        ApplicationContext context = SpringApplication.run(TestApplication.class, args);
    
        
        UserRepository ur = context.getBean(UserRepository.class);
        
        User user = new User();
        user.setName("XYZ");
        user.setStatus("Active");
        user.setCity("OOPS");
        
        User save = ur.save(user);
        System.out.println(save);
    }

}

Entity class (user):

package com.jpa.test;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.GenerationType;
import jakarta.persistence.Id;

@Entity
public class User {
    
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int id;
    
    private String name;
    
    private String city;
    
    private String status;
    
    public User() {
        super();
        // TODO Auto-generated constructor stub
    }

    public User(int id, String name, String city, String status) {
        super();
        this.id = id;
        this.name = name;
        this.city = city;
        this.status = status;
    }

    

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    @Override
    public String toString() {
        return "User [id=" id ", name=" name ", city=" city ", status=" status "]";
    }
    
    

}

Try adding these comments to your program:

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