封装一个springboot的批量新增

以下是一个基本的Spring Boot批量插入的示例：

1.创建一个实体类，例如User：

@Entity
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "name")
    private String name;

    @Column(name = "age")
    private int age;

    // getters and setters
}

2.创建一个UserRepository接口扩展JpaRepository：

public interface UserRepository extends JpaRepository<User, Long> {
}

3.编写一个UserService类：

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;

    @Transactional
    public void batchSave(List<User> userList) {
        userRepository.saveAll(userList);
    }
}

4.在你的控制器中注入UserService类：

@RestController
public class UserController {
    @Autowired
    private UserService userService;

    @PostMapping("/users")
    public void batchSaveUsers(@RequestBody List<User> userList) {
        userService.batchSave(userList);
    }
}

5.现在你可以使用POST请求将数据发送到/users端点进行批量插入了：

curl -X POST -H "Content-Type: application/json" -d '[{"name": "User1", "age": 20}, {"name": "User2", "age": 30}]' http://localhost:8080/users
