Good Night.

I have a problem with persisting an object, hibernate throws an exception saying that the data is too long for the "street" column, of type String.

Follow Pojos and DAO.

Address

@Embeddable
public class Endereco implements Serializable {

    private String cidade;
    private String estado;
    private String rua;
    private String numero;
    private String complemento;

//Gets, Sets, Hash e Equals

Student

@Entity
@Table(name="Aluno", schema="IFBC")
public class Aluno implements Serializable {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int idAluno;

    private int matricula;
    private int rg;

    private String nome;
    private String nomePai;
    private String nomeMae;
    private String naturalidade;
    private String orgaoExpedRG;
    private String obsAlergia;
    private String obsDoencaCronica;
    private String email;
    private String obs;
    private String cpf;

    private boolean possuiDoencaCronica;
    private boolean menorDeIdade;
    private boolean terminouCurso;
    private boolean possuiAlergia;

    @Temporal(javax.persistence.TemporalType.DATE)
    private Date dataInicioCurso;

    @Temporal(javax.persistence.TemporalType.DATE)
    private Date dataTerminoCurso;

    @Temporal(javax.persistence.TemporalType.DATE)
    private Date dataNascimento;

    private long telefone;

    private char sexo;

    @Embedded
    private Endereco endereco;

    @OneToOne
    @JoinColumn(name="idTurma")
    private Turma turma;

    @OneToOne
    @JoinColumn(name="idUsuario")
    private Usuario cadastrante; //Quem cadastrou

    private boolean formado;

            session.delete(obj);
            transaction.commit();

        try {
            iniciarOperacao();
            Criteria criteria = session.createCriteria(cls);
            List list = criteria.list();
            transaction.commit();

            return list;

Would the error be caused by @Embeddable ? It's the first time I work with this.

Thanks in advance!

The error message leaves no doubt: the system is trying to insert the record into the database, but it is sending more characters in the rua field than it fits in that field.

Your entity does not specify the size of the fields, so you can not tell the size of the rua field. I also do not know if the system is generating the tables based on Hibernate or if the database is created in some other way.

If you use Hibernate to generate the tables, I strongly suggest you specify the size of each String column. Example:

@Column(length = 10) 
private String rua;

Otherwise, all fields will be created with the default of 255 characters, which is not legal for modeling.

If, on the other hand, the database is created by another process, check the table or script that creates the table what the size of the field rua .

It would be interesting to add data validation notes to avoid these strange errors. See, for example, the Hibernate Validator documentation.

Finally, check the size of the String that is being placed in the Endereco object. Probably the system is allowing the user to enter a street greater than the size of the table, or is still importing data from somewhere, such as a text file, and does not check if the size of the data fits in the table.

With all this information, you will have to make a decision on how to solve the problem, either by increasing the size of the table field, by cutting the typed data, by limiting user input, etc.
