@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
public class Employee implements Serializable {
private static final long serialVersionUID = 1L;
@TableId(value = "id", type = IdType.AUTO)
private Integer id;
private String lastName;
private String email;
private Integer gender;
private Integer age;
}

返回的实体就会包含主键值

@PostMapping("add")
@ResponseBody
public Employee addEmployee() {
Employee employee = new Employee();
employee.setLastName("chen").setAge(18).setEmail("10000@qq.com").setGender(1);
employeeService.saveOrUpdate(employee);
return employee;
}
|
或者mapper层使用insert方法也会返回主键

@Override
public Employee saveEmp(Employee employee) {
baseMapper.insert(employee);
return employee;
}
