這個錯誤的解決方案： JsonIgnoreProperties({"hibernateLazyInitializer","handler"})//添加這一行app

@Entitythis

@Table(name = "tbl_user")//能夠省略 public class User {.net

[@Id](https://my.oschina.net/u/3451001)@GeneratedValue(strategy = GenerationType.IDENTITY)

private Integer id;

@Column(name = "last_name",length = 50)

private String lastName;

@Column //省略的寫法

private String email;

//下面這篇博客解釋了緣由hibernate
