如何使用MongoDB+Springboot实现分布式ID

实现方式
1.引入mongodb依赖
<!--mongodb -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>
2.创建一个实体类
public class Customer {
@Id
public String id;
public String firstName;
public String lastName;

public Customer() {}
此处省略get,set
}
3.创建mongodb 接口类
public interface CustomerRepository extends MongoRepository<Customer, String> {
public Customer findByFirstName(String firstName);
public List<Customer> findByLastName(String lastName);

}
4.测试类
@Autowired
CustomerRepository customerRepository;
@Test
public void mongodbIdTest(){
Customer customer=new Customer("lxdxil","dd");
customer=customerRepository.save(customer);
logger.info( "mongodbId:"+customer.getId());
}
