This is the Exception I am getting when use Find Method . I am using Spring Boot JPA Repository.

@Entity

@Table(name ="Store") public class StoreEntity {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long store_id;
private String storeDescription;
private String storeName;
private String lattitude;
private String longitude;
private boolean isActive;
private boolean is247;
private Date createdDate;
private Date lastModifiedBy;

@OneToMany(mappedBy = "store", cascade = CascadeType.ALL)
@JsonIgnoreProperties(value ="store", allowSetters=true)
private Set<GroceryItemEntity> groceryItem;

@Table(name ="Grocery") public class GroceryItemEntity {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long grocery_id;

private String name;
private String description;

private double price;
private boolean isActive;
private Date  createdDate;  
private Date  lastModifiedBy;


@ManyToOne(cascade = CascadeType.ALL )
@JoinColumn(name = "store_id")
@JsonIgnoreProperties(value ="groceryItem", allowSetters=true)
private StoreEntity store;

Nice exception. Now it needs a question and some code to be a worthy post. — The Head Rush

You have an infinite recursion problem when when attempting serialization - each StoreEntity has a reference to a set of GroceryItemEntity instances and vice versa. Jackson provides a set of annotations (@JsonIgnore, @JsonIgnoreProperties, and @JsonManagedReference/@JsonBackReference) to work around this problem in various use cases. You just have to evaluate and figure out which one best meets your needs. — The Head Rush

@JsonIgnoreProperties(value ="groceryItem", allowSetters=true)

Used in All Mapping to fixed the issue of infinite recursion.

Actually I changed the Structure of my application.Used Vo in Endpoint instead of Entity Class
