这个错误的解决方案： JsonIgnoreProperties({"hibernateLazyInitializer","handler"})//添加这一行
@Entity
@Table(name = "tbl_user")//可以省略 public class User {
[@Id](https://my.oschina.net/u/3451001)@GeneratedValue(strategy = GenerationType.IDENTITY) private Integer id; @Column(name = "last_name",length = 50) private String lastName; @Column //省略的写法 private String email;
