這篇文章將為大家詳細(xì)講解有關(guān)Spring MVC如何實(shí)現(xiàn)接受表單自動封裝特性,小編覺得挺實(shí)用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
Spring MVC中的Controller可以以實(shí)體類接受來自客戶端的form表單,表單的字段自動構(gòu)成實(shí)體類對象
客戶端的表單
<form action="http://localhost:8080/test/user" method="POST"> <!-- 每個字段名對應(yīng)實(shí)體類 --> <div> <input type="text" name="name"/> </div> <div> <input type="number" name="age"/> </div> <div> <input type="text" name="hobby"/> </div> <input type="submit" value="Submit"/> </form>
實(shí)體類
public class User { private String name; private Integer age; private String hobby; public User() { this.name = "未初始化"; this.age = 10; this.hobby = "coding"; } public User(String name) { this.name = name; this.age = 10; this.hobby = "coding"; } public User(String name, Integer age) { this.name = name; this.age = age; this.hobby = "coding"; } public User(String name, Integer age, String hobby) { this.name = name; this.age = age; this.hobby = hobby; } public Integer getAge() { return age; } public String getHobby() { return hobby; } public String getName() { return name; } public void setAge(Integer age) { this.age = age; } public void setHobby(String hobby) { this.hobby = hobby; } public void setName(String name) { this.name = name; } @Override public String toString() { return "User{" + "name='" + name + '\'' + ", age=" + age + ", hobby='" + hobby + '\'' + '}'; } }
服務(wù)端接收
@Controller @RequestMapping("/test") public class TestController { @RequestMapping(value = "/user", method = RequestMethod.POST) // 控制器會自動實(shí)例化參數(shù) public String user(User user) { System.out.println(user); return "redirect:/test/user"; } @RequestMapping(value = "/user", method = RequestMethod.GET) public String user() { return "form"; } }
