在对 stackoverflow 进行大量研究之后，我发布了这个问题，因为我找不到该问题的解决方案。
需求场景：根据每个客户 ID 作为参数，从客户列表中更新客户。
尝试的解决方案：根据从 jsp 收到的客户 ID，将其作为 Struts2 url 标签传递给 Action。
面临的问题 - URL 上可见的查询字符串。
http://foo.com/Struts2Example/getCustomerAction?customerId=2
问题 ：
- 如果我们使用struts Url标签，我们可以不隐藏查询字符串吗？
- 如果我们在使用 Url 标签时无法隐藏 using 查询字符串？上述情况的替代方案是什么。
下面是 struts.xml、jsp 和操作的代码 -
<h2>All Customers Details</h2>
<s:if test="customerList.size() > 0">
<table border="1px" cellpadding="8px">
<tr>
<th>Customer Id</th>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
<th>Created Date</th>
</tr>
<s:iterator value="customerList" status="userStatus">
<tr>
<td><s:url var="editCustomer" action="getCustomerAction">
<s:param name="customerId" value="%{customerId}" />
</s:url>
<p>
<s:a href="%{editCustomer}">
<s:property value="customerId" />
</s:a>
</p></td>
<td><s:property value="firstname" /></td>
<td><s:property value="lastname" /></td>
<td><s:property value="age" /></td>
<td><s:date name="createdDate" format="dd/MM/yyyy" /></td>
</tr>
</s:iterator>
</table>
</s:if>
<br />
<br />
struts.xml-
<!-- Get Customer Details - To Pre-Populate the form to update a Customer -->
<action name="getCustomerAction" method="getCustomerById"
class="com.hcl.customer.action.CustomerAction">
<result name="success">pages/customerForm.jsp </result>
</action>
客户行动类-
public class CustomerAction extends ActionSupport implements ModelDriven {
Logger logger = Logger.getLogger(CustomerAction.class);
Customer customer = new Customer();
List<Customer> customerList = new ArrayList<Customer>();
CustomerDAO customerDAO = new CustomerDAOImpl();
public Customer getCustomer() {
return customer;
}
//Set Customer onto Value Stack
public void setCustomer(Customer customer) {
this.customer = customer;
}
public List<Customer> getCustomerList() {
return customerList;
}
//Set Customer List onto Value Stack
public void setCustomerList(List<Customer> customerList) {
this.customerList = customerList;
}
public String execute() throws Exception {
return SUCCESS;
}
public Object getModel() {
return customer;
}
// Edit customer details, it will retrieve the records based on customerId
//SkipValidation is used to skip the validate()
@SkipValidation
public String getCustomerById() {
logger.info("** Customer Id to edit ** " + customer.getCustomerId());
customer = customerDAO.customerById(customer.getCustomerId());
return SUCCESS;
}
