    The column código actually exists in the table categoria? How’s your table creation script?

The error is quite clear, as can be seen from this line of stacktrace:

Unknown column 'categoria0_.codigo' in 'field list'

JPA/Hibernate was unable to find a column with the name in its database codigo, as you mapped here:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long codigo;

According to your script DDL:

id BIGINT(20) PRIMARY KEY AUTO_INCREMENT,

the column is called id, soon, the error. See that you will have the same problem with the column nome in Java and name at the bank.

To fix, you have two options:

1) Change in Java the name of the properties so that they are equal to the script of the database.

2) Add above each property in Java the annotation:

@Column(name="nomeIgualAoDoScript")

In this way, the framework ignores the name given to the property and takes into account only the one marked in the annotation.

So, for example, you would have:

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

If this answer solved your problem, mark it as correct to help users who have difficulty similar to yours.
