Exception: No Default Constructor for Entity

Encountering the error "org.hibernate.InstantiationException: No default constructor for entity: : principal.Cliente" indicates the absence of a default constructor in the specified entity class.

Issue Details:

The error occurs when Hibernate attempts to instantiate an object of the Cliente class. Specifically, it cannot find a constructor with no arguments (i.e., a default constructor).

Solution:

To resolve this issue, a default constructor must be provided for the Cliente class. A default constructor has no parameters and initializes the object with default values. In this case, the Cliente class should be modified as follows:

<code class="java">public class Cliente {
    private String name;

    public Cliente() {} // Adding an empty default constructor

    public Cliente(String name) {
        this.name = name;
    }
}</code>

With the addition of the default constructor, Hibernate can now instantiate objects of the Cliente class successfully, eliminating the instantiation exception.
