Java technology stack for building large-scale enterprise-level applications

With the rapid development of the Internet, the need for large-scale enterprise-level applications is becoming more and more urgent. As one of the most commonly used programming languages ​​in the world, Java has become the preferred technology for building these applications because of its stability, reliability and cross-platform nature.

In the process of building large-scale enterprise-level applications, various Java technologies are often used to meet different needs. In this article, we will introduce some of the major Java technologies and frameworks, along with examples of their use in building large-scale enterprise applications.

  1. Spring Framework: Spring is a lightweight Java development framework for building enterprise-level applications. It provides a simple and flexible way to develop Java applications while also providing integrated support for various other technologies such as Hibernate, MyBatis, JDBC, etc. The following is a sample code using the Spring framework:
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

  1. Hibernate framework: Hibernate is a persistence framework used to map Java objects to relational databases. It provides a simple way to manage database operations, including adding, deleting, modifying and querying data. The following is a sample code using the Hibernate framework:
@Entity
@Table(name = "users")
public class User {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(name = "username")
    private String username;
    
    @Column(name = "password")
    private String password;
    
    // Getters and setters
}

@Repository
public class UserRepository {

    @Autowired
    private SessionFactory sessionFactory;

    public User getUserById(Long id) {
        return sessionFactory.getCurrentSession().get(User.class, id);
    }
    
    // Other database operations
}
Copy after login
  1. Spring MVC Framework: Spring MVC is a Java-based framework for developing web applications that provides a model-view- Controller (MVC) architecture for decoupling different parts of an application. The following is a sample code using the Spring MVC framework:
@Controller
@RequestMapping("/users")
public class UserController {

    @Autowired
    private UserRepository userRepository;

    @GetMapping("/{id}")
    public String getUser(@PathVariable Long id, Model model) {
        User user = userRepository.getUserById(id);
        model.addAttribute("user", user);
        return "user";
    }
    
    // Other request mappings
}
Copy after login
  1. MyBatis Framework: MyBatis is a simple and easy-to-use persistence framework for executing SQL queries and mapping the results to Java objects middle. It provides a simple method to operate relational databases, including adding, deleting, modifying and querying data. The following is a sample code using the MyBatis framework:
@Mapper
public interface UserMapper {

    @Select("SELECT * FROM users WHERE id = #{id}")
    User getUserById(Long id);
    
    // Other SQL queries
}

@Service
public class UserService {

    @Autowired
    private UserMapper userMapper;

    public User getUserById(Long id) {
        return userMapper.getUserById(id);
    }
    
    // Other business logic
}
Copy after login

In addition to the main Java technologies and frameworks mentioned above, other technologies and frameworks can also be used to meet specific needs, such as Spring Boot, Spring Security, Ehcache, Redis, etc.

To sum up, the Java technology stack for building large-scale enterprise-level applications can choose the appropriate technology and framework based on actual needs. Whether it is the Spring framework, Hibernate framework, Spring MVC framework or MyBatis framework, they all provide convenient development methods and powerful functions at different levels to help developers efficiently build large-scale enterprise applications.

We hope that the sample code and introduction in this article can help readers better understand and apply the Java technology stack, thereby building large-scale enterprise-level applications with more stability and reliability.
