For example: mysql has two fields create table testa (id bigint not null,
name varchar (20), primary key (id)) and in Ignite corresponding entity
class private Long id; private String name; When using springboot to start
The client creates an entity class object using the object's Set method to
copy the ID field to the object. SetID (11L); Object. SetName ("hello");
Then call the IgniteRepository Save method to save the value of the object
to the Cache, call IgniteRepository FindOne method in the query ID can see
the contents of the ID, but by connecting the JDBC client insert into
CacheName (id, name) values (12, 'hello') After inserting data in the
FindOne method called IgniteRepository, Name field can be seen To content
but ID returns NULL-- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
