Spring MVC 表单标签

添加 Spring 表单标签引用

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

运动员类

1@Component
2public class Athlete {
3    private String lastName;
4
5    public Athlete() {
6    }
7
8    public String getLastName() {
9        return lastName;
10    }
11
12    public void setLastName(String lastName) {
13        this.lastName = lastName;
14    }
15}

AthleteController 类

1@Controller
2public class AthleteController {
3
4    // 处理 /showPlayerForm 请求的方法
5
6    // 处理 /processPlayerForm 请求的方法
7}

使用 @RequestMapping 进行类级别映射

1@Controller
2@RequestMapping("/player")
3public class AthleteController {
4
5    // 处理 /showPlayerForm 请求的方法
6
7    // 处理 /processPlayerForm 请求的方法
8}

创建 showForm() 方法

1@RequestMapping("/showPlayerForm")
2public String showForm(Model model) {
3    model.addAttribute("athlete", new Athlete());
4    return "add-player-form";
5}

在 processForm() 方法中添加 @ModelAttribute 注解

1@RequestMapping("/processPlayerForm")
2public String processForm(@ModelAttribute("athlete") Athlete myAthlete) {
3    return "player-confirmation";
