I am using spring boot 2 with hibernate and redis.
I am able to get my object into redis however when spring tries to get the
object back out I am getting the following error:
*Could not write JSON: failed to lazily initialize a collection of role:
de.codeboje.springboot.tutorials.caching.model.Location.images, could not
initialize proxy - no Session; nested exception is
com.fasterxml.jackson.databind.JsonMappingException: failed to lazily
initialize a collection of role:
de.codeboje.springboot.tutorials.caching.model.Location.images, could not
initialize proxy - no Session (through reference chain:
de.codeboje.springboot.tutorials.caching.model.Location[\"parent\"]->de.codeboje.springboot.tutorials.caching.model.Location[\"parent\"]->de.codeboje.springboot.tutorials.caching.model.Location[\"images\"]*
here is the code if someone can point me in the right direction I would
appreciate it
=========================== Code follows below ================
@Data
@ToString
@EqualsAndHashCode
@Entity(name="locationimage")
public class LocationImage implements Serializable{
/**
*
*/
private static final long serialVersionUID = -2443135589636413335L;
@JsonIgnore
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@JsonProperty(value="imageName")
private String name;
@JsonProperty(value="imageValue")
private String value;
@JsonIgnore
@EqualsAndHashCode.Exclude
private ActivityTracking tracking;
@JsonIgnore
private Boolean active;
@JsonIgnore

@JoinColumn(name = "locationId")
private Location locationImage;
}
@Entity(name = "location")
@DynamicUpdate(value = true)
@Data

@AllArgsConstructor
public class Location implements Serializable {
/**

private static final long serialVersionUID = -6772358081259494374L;
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;

private Float squareFeet;
private String constructionCode;

private Boolean external;
private Long locationTypeId;
private String floor;
@Temporal(TemporalType.DATE)
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
private Date substantialCompletionDate;
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "addressId")
@EqualsAndHashCode.Exclude
private Address address;
@EqualsAndHashCode.Exclude
private ActivityTracking tracking;
@ManyToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "parentId")
@EqualsAndHashCode.Exclude
private Location parent;
// line below is causing the error
@OneToMany(mappedBy = "locationImage", fetch = FetchType.LAZY)
@Builder.Default
@EqualsAndHashCode.Exclude
private Set<LocationImage> images = new HashSet<LocationImage>();
}
@Service
@Slf4j
public class LocationService {
@Autowired
LocationRepository locationRepository;
@Cacheable("location")
public Location findById(Long id) {
log.info("findById called for id {}", id);
return locationRepository.findOne(id);
}
@CacheEvict(value = "location", allEntries = true)
public void clearCache() {
log.info("Clearing location cache");
}
}
=================== End of code =================
Thanks in advance for any help
