问题描述：在使用Spring Data Jpa的JpaRepository的getOne()方法查询数据实体时报以下错误：

org.hibernate.LazyInitializationException: could not initialize proxy [com.xx.xxx.entity.TbUser#1] - no Session 

解决方法：出现这个问题是由于Hibernate的懒加载引起的，我们可以在对应的实体类上添加@Proxy(lazy = false)注解配置来解决这个问题

import lombok.Data;
import org.hibernate.annotations.Proxy;
import javax.persistence.*;
import java.util.Date;
 
@Proxy(lazy = false)
@Data
@Entity
@Table(name = "tb_user")
public class TbUser {
 
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private Integer id;
 
    @Column(name = "name")
    private String name;
 
    @Column(name = "age")
    private Integer age;
 
    @Column(name = "create_time")
    private Date createTime;
 
    @Column(name = "update_time")
    private Date updateTime;
}
