想把string转int,又不想用强制类型转换的时候
比如单选钮的value必须跟的是String,而后台提交又想提交int,而value写的时候是英文字母,不是数字的String,又不想改,这时强制类型转换就不好用了,所以,就有了下面的代码
package struts.form;
import java.util.* ;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;
public class RationDrawInvoiceForm extends ActionForm {
private String rationDrawInvoiceMoney;
int rationDrawInvoiceMoneyInt ;
private List errors ;
public void setErrors(List errors)
{
this.errors = errors ;
}
public List getErrors()
{
return this.errors ;
}
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
return null;
}
public void reset(ActionMapping mapping, HttpServletRequest request) {
rationDrawInvoiceMoney = "fifty" ;
}
public String getRationDrawInvoiceMoney() {
if(rationDrawInvoiceMoney.equals("fifty"))
{
this.rationDrawInvoiceMoneyInt = 50 ;
}
if(rationDrawInvoiceMoney.equals("oneHundred"))
{
this.rationDrawInvoiceMoneyInt = 100 ;
}
if(rationDrawInvoiceMoney.equals("twoHundred"))
{
this.rationDrawInvoiceMoneyInt = 200 ;
}
return rationDrawInvoiceMoney;
}
public void setRationDrawInvoiceMoney(String rationDrawInvoiceMoney) {
this.rationDrawInvoiceMoney = rationDrawInvoiceMoney;
}
public int getRationDrawInvoiceMoneyInt() {
return rationDrawInvoiceMoneyInt;
}
public void setRationDrawInvoiceMoneyInt(int rationDrawInvoiceMoneyInt) {
this.rationDrawInvoiceMoneyInt = rationDrawInvoiceMoneyInt;
}
}
红色部分是后加上去的,而不是jsp提交来的值,这样写了之后,可以在action里直接像调用其他属性一样来调用转换成int的变量,调用过去后就已经转换成int了
