Question

SpringMVC如何用实体对象接收参数

Answer 1

1.jsp页面 -->提交的表单

<form action="abc" method="post">
姓名<input type="text" name="username" ><br>
密码<input type="text" name="password" ><br>
手机号<input type="text" name="phone" ><br>
<button type="submit">点击测试</button>
</form>

2.实体类 -->pojo (User)

public class User {
private String username;
private String password;
private String phone;
。。。。省略getter/setter方法

3.接收controller --> HelloController
@Controller
public class HelloController {
@RequestMapping("/itemList")
public ModelAndView itemList(User user){
System.out.println(user);
ModelAndView ma=new ModelAndView();
ma.setViewName("/hello.jsp");
return ma;
}
