以bindFromRequest（）。get（）方式獲取值時，它只返回null值。我得到所有String類型爲null且integr爲zer0。這裏是我的控制器和模型封裝代碼，我怎麼能解決這個錯誤：同時獲取表單中的值時返回空值
enter code here
In controller:
public static Result getShow(){
Register register=Form.form(Register.class).bindFromRequest().get();
register.save();
System.out.println(register);
return ok("@Required annotation kicked in.."+register);
}
In Models:
package models;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
@Entity
@Table(name="register")
public class Register {
//private static final long serialVersionUID = 1L;
private String firstname;
private String lastname;
@Id
private String displayname;
private String date;
private String email;
private String password;
private String confirm_password;
private String gender;
private int phone_no;
private String address;
private int zipcode;
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 getDisplayname() {
return displayname;
}
public void setDisplayname(String displayname) {
this.displayname = displayname;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getConfirm_password() {
return confirm_password;
}
public void setConfirm_password(String confirm_password) {
this.confirm_password = confirm_password;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public int getPhone_no() {
return phone_no;
}
public void setPhone__no(int phone_no) {
this.phone_no = phone_no;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public int getZipcode() {
return zipcode;
}
public void setZipcode(int zipcode) {
this.zipcode = zipcode;
}
}
