我正在尝试使用存储过程列出所有员工，而我的要求是通过调用该过程来获取员工的所有详细信息。下面是我的代码
@Entity
@Table(name="employee")
@NamedStoredProcedureQueries({@NamedStoredProcedureQuery( name ="Listall",
procedureName = "list_emp")})
public class Employee {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private int id;
@Column(name = "Name")
private String Name;
@Column(name="SALARY")
private int Salary;
public int getId() {
return id;
}
public String getName() {
return Name;
}
public int getSalary() {
return Salary;
}
public void setId(int id) {
this.id = id;
}
public void setName(String name) {
Name = name;
}
public void setSalary(int salary) {
Salary = salary;
}
}
@Repository
public interface EmployeeRepository extends CrudRepository<Employee, Integer>{
@Procedure(name ="Listall")
public List<Employee> get_employee();
}
@Service
public class EmployeeService {
@Autowired
private EmployeeRepository Erp;
public List<Employee> GetAll(){
return Erp.get_employee();
}
}
@RestController
@RequestMapping("/employee")
public class EmployeeController {
@Autowired
EmployeeService eservice;
@RequestMapping(value="/all", method = RequestMethod.GET)
public List<Employee> getAll(){
return eservice.GetAll();
}
在提交获取请求时获取Follow异常。
