The problem is that you forgot to have <generator class="increment"/> for the id in your Fieldclass.

So try this:

@Id 

@GenericGenerator(name="gen",strategy="increment") 

@GeneratedValue(generator="gen") 

@Column(name = "ID", unique = true, nullable = false, precision = 15, scale = 0) 

private Long id;

试试这个吧
