Spring MVC中的Controller可以以实体类接受来自客户端的form表单，表单的字段自动构成实体类对象
客户端的表单
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 + ''' + '}'; } }
服务端接收
@Controller @RequestMapping("/test") public class TestController { @RequestMapping(value = "/user", method = RequestMethod.POST) // 控制器会自动实例化参数 public String user(User user) { System.out.println(user); return "redirect:/test/user"; } @RequestMapping(value = "/user", method = RequestMethod.GET) public String user() { return "form"; } }
