java - Java Struts2 - struts タグを使用して配列リストを作成し、ユーザーが値を入力してからアクションに渡すにはどうすればよいですか?

Question

私は Struts 2 の初心者で、Struts タグを使用して JSP で配列リストを作成したいと考えています。そして、入力された値をアクションに渡す必要があります。また、アクションから JSP に戻すにはどうすればよいですか?

public class BookingListAction extends ActionSupport {

    private Boolean isDebit;
    private BigDecimal amount;
    private BigDecimal phpAmount;
    private String currency;
    private String glAccountName;
    private BigDecimal glAccountNumber;
    private String misCode;
    private String branchCode;
    private String branchName;

    public Boolean getIsDebit() {
        return isDebit;
    }

    public void setIsDebit(Boolean isDebit) {
        this.isDebit = isDebit;
    }

    public BigDecimal getAmount() {
        return amount;
    }

    public void setAmount(BigDecimal amount) {
        this.amount = amount;
    }

    public BigDecimal getPhpAmount() {
        return phpAmount;
    }

    public void setPhpAmount(BigDecimal phpAmount) {
        this.phpAmount = phpAmount;
    }

    public String getCurrency() {
        return currency;
    }

    public void setCurrency(String currency) {
        this.currency = currency;
    }

    public String getGlAccountName() {
        return glAccountName;
    }

    public void setGlAccountName(String glAccountName) {
        this.glAccountName = glAccountName;
    }

    public BigDecimal getGlAccountNumber() {
        return glAccountNumber;
    }

    public void setGlAccountNumber(BigDecimal glAccountNumber) {
        this.glAccountNumber = glAccountNumber;
    }

    public String getMisCode() {
        return misCode;
    }

    public void setMisCode(String misCode) {
        this.misCode = misCode;
    }

    public String getBranchCode() {
        return branchCode;
    }

    public void setBranchCode(String branchCode) {
        this.branchCode = branchCode;
    }

    public String getBranchName() {
        return branchName;
    }

    public void setBranchName(String branchName) {
        this.branchName = branchName;
    }
}

アクション

public class BookingAction extends ActionSupport {

    private List<BookingListAction> bookingList = new ArrayList<BookingListAction>();

    public String execute() {

        try {
            getBookingList();
            System.out.println(getBookingList());
        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

    public List<BookingListAction> getBookingList() {
        return bookingList;
    }

    public void setBookingList(List<BookingListAction> bookingList) {
        this.bookingList = bookingList;
    }

}

JSP

<%@ taglib prefix="s" uri="/struts-tags" %>

<form id="bookingDebitCreditForm" action="BookingDebitCredit" method="POST">

    <s:textfield name="bookingListItem['0'].amount"/>

    <s:iterator value="bookingList" var="bookingListItem" status="key">
        <s:textfield name="bookingListItem[%{#key.index}].amount"/>
    </s:iterator>

    <button type="button" class="btn btn-flat btn-info" id="saveBookingJson">save</button>
    <button type="button" class="btn btn-info btn-raised">back</button> 

</form>

問題は、ユーザーが配列リストに値を入力する方法がわからないことです。また、アクションで使用できるように JSP から取得するにはどうすればよいですか? 前もって感謝します。

新しい JSP

    <%@ taglib prefix="s" uri="/struts-tags" %>

<form id="bookingDebitCreditForm" action="BookingDebitCredit" method="POST">
    <div>
        <table>
            <tr>
                <td>
                    Amount: 
                </td>
                <td>
                    <s:textfield name="bookingList[%{#key.index}].amount" theme="simple"/>
                </td>
            </tr>
        </table>
            <table> 
            <s:iterator value="bookingDebitCreditList" id="array" status="key">
              <tr>
                  <td><s:textfield name="array[%{#key.index}].amount" value="%{amount}" theme="simple"/></td>
              </tr>
            </s:iterator>
            </table>
    </div>

    <button type="submit" class="btn btn-flat btn-info">save</button>
    <button type="button" class="btn btn-info btn-raised">back</button> 

</form>
