</plugins>
1-3】service.EmployeeService
@Service

}
}
1-4】controller.EmployeeController
@Controller
public class EmployeeController {
@Autowired

/**
* 查询所有数据的方法
*/
@RequestMapping(value = "/emps",method = RequestMethod.GET)
public String getALl(
@RequestParam(value = "pn",defaultValue="1") Integer pn,
Model model){
// 当前页，和页数显示数量
PageHelper.startPage(pn,5);
List<Employee> allInfo = employeeService.getAllInfo();
// 显示底部页码个数，五个
PageInfo<Employee> objectPageInfo = new PageInfo<>(allInfo,5);
model.addAttribute("pageInfo",objectPageInfo);
return "list";
}
}
