我正在用struts开发一个在线图书库应用程序......
我有一个用户表单，用户将在其中输入他的详细信息，例如名字，姓氏等，还有一个书籍列表，他将在其中选择一些他想要的书籍..稍后我想将这些详细信息插入到 2 个表中..即 obl_users 中的用户详细信息以及用户在 users_books 中选择的书籍。
我将以下代码用于列表..
<%
if(request.getAttribute("booksNameList") != null) {
%>
<html:select property="displayBooks" multiple="true" size="5">
<logic:iterate id="booksNameList" name="booksNameList" scope="request">
<html:option value="${booksNameList.bookId}" ><bean:write name="booksNameList" property="longTitle" /></html:option>
</logic:iterate>
</html:select>
<%
}
%>
最初，当用户请求表单时，表单将预先填充列表将数据库中的所有书籍名称..我不确定我为在 ie 的值部分中获取书籍 ID 而编写的代码 value="${booksNameList.bookId}"..
在我的 addUser() 中，我想像这样遍历用户选择的书籍..
for (int i = 0; i < selectedBooks.length; i++) {
//insertBooks.setInt(1, generatedKeys.getInt(1));
//insertBooks.setInt(2, Integer.parseInt(selected[i]));
//insertBooks.addBatch();
}
但为此如何让用户选择书籍..
这是我的 user.java
public class User extends ActionForm {
private int userId;
private String firstName;
private String lastName;
private String middleName;
private String username;
private String password;
private String contactNumber;
private String membershipNumber;
private String role;
private String email;
private String address;
private String comments;
private String dateOfBirth;
private int oblStatus;
private String createdDate;
private String updatedDate;
private String createdBy;
private String updatedBy;
private String displayBooks;
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
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 getMiddleName() {
return middleName;
}
public void setMiddleName(String middleName) {
this.middleName = middleName;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getContactNumber() {
return contactNumber;
}
public void setContactNumber(String contactNumber) {
this.contactNumber = contactNumber;
}
public String getMembershipNumber() {
return membershipNumber;
}
public void setMembershipNumber(String membershipNumber) {
this.membershipNumber = membershipNumber;
}
public String getRole() {
return role;
}
public void setRole(String role) {
this.role = role;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getComments() {
return comments;
}
public void setComments(String comments) {
this.comments = comments;
}
public String getDateOfBirth() {
return dateOfBirth;
}
public void setDateOfBirth(String dateOfBirth) {
this.dateOfBirth = dateOfBirth;
}
public int getOblStatus() {
return oblStatus;
}
public void setOblStatus(int oblStatus) {
this.oblStatus = oblStatus;
}
public String getCreatedDate() {
return createdDate;
}
public void setCreatedDate(String createdDate) {
this.createdDate = createdDate;
}
public String getUpdatedDate() {
return updatedDate;
}
public void setUpdatedDate(String updatedDate) {
this.updatedDate = updatedDate;
}
public String getCreatedBy() {
return createdBy;
}
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
public String getUpdatedBy() {
return updatedBy;
}
public void setUpdatedBy(String updatedBy) {
this.updatedBy = updatedBy;
}
public String getDisplayBooks() {
return displayBooks;
}
public void setDisplayBooks(String displayBooks) {
this.displayBooks = displayBooks;
}
}
书豆类：
private String bookId;
private String longTitle;
private String shortTitle;
private String isbn;
private String dateOfPublication;
private String noOfPages;
private String boundType;
private String dvdAvailability;
private String noOfAvailableCopies;
private int oblStatus;
private String createdDate;
private String updatedDate;
private String createdBy;
private String updatedBy;
private String displayAuthors;
private int[] authorIds;
请指导我......我对struts完全陌生
