求助：redis缓存实体类，为什么@class类路径后有$HibernateProxy$

Question

key序列化器：StringRedisSerializer
value序列化器：GenericJackson2JsonRedisSerializer

下面是缓存中的数据

{
    "@class": "com.cloud.infrastructure.security.entity.SecurityInfo$HibernateProxy$P90Wrhtb",
    "enterpriseId": "a1",
    "validateKey": "encrypt",
    "lastIP": "192.168.167.11",
    "domainName": "xxx",
    "seed": 0,
    "token": "e81ab7ac-0e77-4db8-b06a-027e88b7942d",
    "liveTime": 5,
    "lastVisitTime": [
        "java.util.Date",
        1545205307900
    ]
}

下面是实体类

@Table(name = "demo_security_info")
@Data
@Entity
@JsonIgnoreProperties({ "handler","hibernateLazyInitializer" })
public class SecurityInfo implements Serializable {

    @Id
    @Expose
    @Column(name = "enterprise_id")
    private String enterpriseId;

    @Expose
    @Column(name = "validate_key")
    private String validateKey;

    @Expose
    @Column(name = "last_ip", columnDefinition = "inet")
    private String lastIP;

    @Expose
    @Column(name = "domain_name")
    private String domainName;

    @Expose
    @Column(name = "seed")
    private int seed;

    @Expose
    @Column(name = "token")
    private String token;

    @Expose
    @Column(name = "live_time")
    private int liveTime;

    @Expose
    @Column(name = "last_visit_time")
    private Date lastVisitTime;
}

反序列化时报错，把$HibernateProxy$P90Wrhtb删掉就不报错了，求教，该怎么办

找到原因了，原来是缓存方法中使用了JPA的getOne方法，返回的是一个实体的引用-_-
