No Default Constructor for Entity: A Hibernate Exception
In the provided Java code, an exception is encountered when attempting to use Hibernate to instantiate an entity. The error message states: "No default constructor for entity: : principal.Cliente." This exception indicates that the specified entity class, principal.Cliente, does not have a default constructor.
The default constructor is a constructor with no arguments. It is required for Hibernate to instantiate the entity without passing any specific values. In the absence of a default constructor, Hibernate cannot create instances of the entity and raises this exception.
To resolve this issue, modify the principal.Cliente class to include a default constructor:
<code class="java">public class Cliente { private String name; public Cliente() { } public Cliente(String name) { this.name= name; } }</code>
This modification provides the entity class with a default constructor, enabling Hibernate to instantiate it without any arguments. By including this constructor, Hibernate can now successfully create instances of the principal.Cliente entity and eliminate the exception.
