Controller
demo.yangxu.springboot.controller.EmployeeController
//员工添加功能
//SpringMVC自动将请求参数和入参对象的属性进行一一绑定；
//要求请求参数的名字和javaBean入参的对象里面的属性名是一样的
@PostMapping("/emp")
public String addEmp(Employee employee){
//保存员工信息
employeeDao.save(employee);
//添加完成后，进入员工列表
// redirect: 表示重定向到一个地址 /代表当前项目路径
// forward: 表示转发到一个地址
return "redirect:/emps";
}

处理日期的格式问题
将字符串类型转换为 Date 类型，涉及到类型转换和格式化。
默认要求的日期格式为：2020/06/14
在 application.properties 中配置日期格式化：
spring.mvc.format.date=yyyy-MM-dd
