java - Hibernate 找不到我的 hibernate.cfg.xml 文件

Question

非常愚蠢/简单的问题。进行作业和 hibernate 找不到我的 hibernate.cfg.xml 文件。我正在使用 IntelliJ，它位于我的 src 文件夹内。请参阅下面我的代码。

主要:

public class Main {
    public static void main(String[] args) {

        Employee tempEmployee = new Employee("Ronald", "Customer Service", true);
        EmployeeDAO employeeDAO = new EmployeeDAO();
        employeeDAO.saveEmployee(tempEmployee);

    }
}

DAO:

public class EmployeeDAO {

    SessionFactory sessionFactory = new Configuration()
            .configure()
            .addAnnotatedClass(Employee.class)
            .buildSessionFactory();


    public void saveEmployee(Employee employee){
        Session session = sessionFactory.getCurrentSession();

        try {

            session.beginTransaction();
            session.save(employee);
            session.getTransaction().commit();

        } finally {
            session.close();
        }

    }
}

实体:

@Entity
@Table(name = "employee")
public class Employee {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private long id;

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

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

    @Column(name = "working")
    private boolean working;

    public Employee(){}

    public Employee(String name, String department, boolean working) {
        this.name = name;
        this.department = department;
        this.working = working;
    }

    @Override
    public String toString() {
        return "Employee{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", department='" + department + '\'' +
                ", working=" + working +
                '}';
    }

    public long getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public String getDepartment() {
        return department;
    }

    public void setDepartment(String department) {
        this.department = department;
    }

    public boolean isWorking() {
        return working;
    }

    public void setWorking(boolean working) {
        this.working = working;
    }
}

hibernate 配置:
