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

GenericGenerator
