How to get single row from entity in JPA?

Table: Employee

```
    @Id
    private int empId;
    private String empName;
    ...    

```

JPA by default return List. I`m trying to fetch single row.

EmployeeRepository :-

```
    public Employee findByEmpName(String empName);

```

**Another way is to do it, @Query should be use.** 

```
    @Query(value="select e from Employee e where empName = ?1 limit 1", nativeQuery=true)
    public Employee findByEmpName(String empName);

```

How can i ensure that it return single row and correct result.
Any help appreciated.. Thanks in advance.
