java.lang.Object
  ∟java.lang.Enum<jakarta.persistence.FetchType>
    ∟jakarta.persistence.FetchType
Implemented Interfaces:
Constable, Comparable<E>, Serializable
Defines strategies for fetching data from the database.
  • The EAGER strategy is a requirement on the persistence provider runtime that data must be eagerly fetched.
  • The LAZY strategy is a hint to the persistence provider runtime that data should be fetched lazily when it is first accessed. The implementation is permitted to eagerly fetch data for which the LAZY strategy hint has been specified.

Example: 

 @Basic(fetch = LAZY)
 protected String getName() { return name; }
