“No Persistence Unit Found” error

Question

I am getting the following error:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name \'org.springframework.transaction.interc         


        

Answer 1

This error can happen if you have a hibernate mapped class with relations with another non-mapped class, a solution is to check the relation item as @transient (hibernate will ignore it, use this just to check if this is the error, and later map the related class). Example:

@Entity
public class City {

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

private String name;

@Transient
private State state;

public int getId() {
    return id;
}

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

public String getName() {
    return name;
}

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

public State getState() {
    return state;
}

public void setState(State state) {
    this.state = state;
}

}

And this is the non-mapped class which may give the error:

public class State {

private String name;

}
