JPA Entity attribute names missing in generated JSON

Question

I am using JPA and and Jackson is used for generating JSON

Emp.java

@Entity
@NamedQuery(name = \"Emp.findAll\", 
           query = \"select o.empNo, o.         


        

Answer 1

NAmed Query select o.empNo, o.empName from Emp o will return List where as select o from Emp o will return List, so accordingly json will be produced.

You can change the query as below

select new Emp(o.empNo, o.empName) from Emp o and have a constructor in your class accordingly.

or try using

select new Map(o.empNo as empNo , o.empName as empName) from Emp o
