Spring MVC表单单选按钮

Spring MVC表单单选按钮使我们一次只能选择一个选项。此标签呈现单选类型的HTML输入标签。

句法

除了单选按钮标签，Spring MVC的表单标签库也包含单选按钮标签。此标签呈现带有radio类型的多个HTML输入标签。

Spring MVC表单单选按钮的示例

1.将依赖项添加到pom.xml

          

    org.springframework
    spring-webmvc
    5.1.1.RELEASE


    
  
    javax.servlet  
    servlet-api  
    3.0-alpha-1  


    

    javax.servlet
    jstl
    1.2



    org.apache.tomcat
    tomcat-jasper
    9.0.12

2.创建bean类

Reservation.java

package com.javatpoint;

public class Reservation {

    private String firstName;
    private String lastName;
    private String Gender;
    
    public Reservation()
    {        
    }
    public String getFirstName() {
        return firstName;
    }
    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }
    public String getLastName() {
        return lastName;
    }
    public void setLastName(String lastName) {
        this.lastName = lastName;
    }
    public String getGender() {
        return Gender;
    }
    public void setGender(String gender) {
        Gender = gender;
    }    
}

3.创建控制器类

ReservationController.java

package com.javatpoint;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;

@RequestMapping("/reservation")
@Controller
public class ReservationController {
    @RequestMapping("/bookingForm")
public String bookingForm(Model model)
{
      //create a reservation object 
    Reservation res=new Reservation();
      //provide reservation object to the model 
    model.addAttribute("reservation", res);
    return "reservation-page";
}
@RequestMapping("/submitForm")
public String submitForm(@ModelAttribute("reservation") Reservation res)
{
    return "confirmation-form";
}
}

4.在web.xml文件中提供控制器的条目

web.xml



  SpringMVC
     
    spring  
    org.springframework.web.servlet.DispatcherServlet  
    1    
  
  
    spring  
    /

5.在xml文件中定义bean

spring-servlet.xml

6.创建请求的页面

index.jsp




    Railway Registration Form


Click here for reservation.

7.创建视图组件

Reservation-page.jsp

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>



    Reservation Form


Railway Reservation Form


    
        First name:         
        


        Last name: 
        


        Gender: 
        Male 
        Female

确认页面.jsp





Your reservation is confirmed successfully. Please, re-check the details.

First Name : ${reservation.firstName} 

Last Name : ${reservation.lastName} 

Gender: ${reservation.gender}

输出：
