字段，
对于字段：一个用于dateOfBirth，一个用于年龄。
用户可以通过jQuery Datepicker脚本选择自己的出生日期，该脚本会自动计算其年龄供以后使用。
我想使用SpringMVC自动设置的计算年龄属性。我不确定如何从jQuery脚本中检索计算出的年龄。
我的.jsp页面
import org.springframework.format.annotation.DateTimeFormat;
import java.util.Date;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
import javax.validation.constraints.Email;
import com.luv2code.springdemo.mvc.validation.CourseCodeDefinitions;
import com.luv2code.springdemo.mvc.validation.DateConverter;
public class Customer {
@Temporal(TemporalType.DATE)
@DateTimeFormat(pattern = "dd-MM-yyyy")
private Date birthdate;
private String age;
public String getBirthdate() {
return DateConverter.formatDateToStringFormat(birthdate);
}
public void setBirthdate(Date birthdate) {
System.out.println("Debug: Customer.java setBirthdate()-> birthdate: " +birthdate);
System.out.println("Debug: Customer.java setBirthdate()-> birthdate type: " + birthdate.getClass().getSimpleName());
this.birthdate = birthdate;
System.out.println("Debug: Customer.java setBirthdate()-> Exiting setBirthday()");
}
public String getAge() {
//this keeps printing null
return age;
}
public void setAge(String age) {
this.age = age;
}
}
我的客户实体.java文件
@RequestMapping("/processForm1")
public String processForm1(
@ModelAttribute("customer") Customer theCustomer) {
System.out.println("Debug: CustomerController.java processForm1() => DoB: " + theCustomer.getBirthdate());
System.out.println("Debug: CustomerController.java processForm1() => DoB type: " + theCustomer.getBirthdate().getClass().getSimpleName());
//this keeps printing null :(
System.out.println("Customer age: " + theCustomer.getAge());
return "customer-confirmation";
}
我的控制器类
val set = setOf<String>("one", "two")
从上面的类中可以看到，每当我尝试从getAge（）函数中检索用户年龄时，它会一直打印空值，而不是从日期选择器中选择的用户值。将由springMVC通过jQuery datepicker正确设置，以便我能够检索和操作保存在客户对象中的数据？
感谢您的任何帮助！
