Hibernate lazy loading with repeated data

Question

I have two tables employee and bankname. In employee table there is a column bank_name_id which refers the column of bank table.

I have mapped employee bank_name_id with bank bank_name_id with many to one

I'm using spring mvc @RestController while returning it correctly fetch the data from bankname but converting into json its have repeated fetched data

Table 1    Employee Table:
empid empname bank_name_id
1     XXX      1

Table 2    Bankname table
bank_name_id bank_name
1             QQQ

JSON output:

{
    empid:1,
    empname:"xxx",
    bank:{bank_name_id:1,bank_name:QQQ},
    bankname:{bank_name_id:1,bank_name:QQQ}
}

this bankname data is repeated

Can you share xml or annotation mapping. – Burak Keceli Nov 04 '15 at 13:50 — Burak Keceli, Nov 04 '15 at 13:50
