i am using spring boot want to return all list of my Employee class using @Query() annotation but it returns exception here is my code //here is my repository clas

package com.employee.Dao;

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;

import com.employee.Entities.Employee;

@Repository
public interface UserRepository extends CrudRepository<Employee,Long> {
    
    @Query("select e FROM Employee e")
    public <List>Employee getAllEmployee();
    
    @Query(value = "  From Employee e where e.fullName=:name")
    public <List>Employee getEmployeeByName(@Param("name") String name);

}

Here is my controller class

@GetMapping("/main")
public String main(@ModelAttribute Employee employee, ModelMap model, HttpSession session) {

I am using Spring Boot and Hibernate.

You should mention which field OR fields you need as result. It looks like you only have ClassCastException with second query because you didn't mention which details you need in result but set <List>Employee return type in query.

Update your query with this and try. It might solve your ClassCastException

@Query(value = "SELECT e FROM Employee e WHERE e.fullName = :name")
public List<Employee> getEmployeeByName(@Param("name") String name);
