主类代码：

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);
    }

}
