这是action
package action;
import java.util.List;
import com.opensymphony.xwork2.ActionSupport;
import DAO.CustomerInfo;
import ADO.Customer;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;
public class customerList extends ActionSupport{
private static final long serialVersionUID = 1L;
/**
*
*/
private static List<Customer> customer1;
private CustomerInfo customerinfo;
public CustomerInfo getCustomerinfo() {
return customerinfo;
}
public void setCustomerinfo(CustomerInfo customerinfo) {
this.customerinfo = customerinfo;
}
public List<Customer> getCustomer() {
return customer1;
}
public void setCustomer(List<Customer> customer) {
customerList.customer1 = customer;
}
public String execute() throws Exception{
HttpServletRequest request=ServletActionContext.getRequest();
customer1= CustomerInfo.querycustomer();
request.setAttribute("customer",customer1);
return SUCCESS;
}
public static void main(String[] args) {
System.out.println(CustomerInfo.querycustomer());
}
}
这是操作方法
public static List querycustomer()
{
List list = new ArrayList();
Customer customer;
Configuration cfg = new Configuration().configure();
SessionFactory sf = cfg.buildSessionFactory();
Session session = sf.openSession();
Transaction tx = session.beginTransaction();
Query query = session.createQuery("from Customer");
List<?> list1 = query.list(); // 序列化函数
Iterator<?> it = list1.iterator(); //迭代
while (it.hasNext())
{
customer = (Customer)it.next();
//System.out.println(customer.getUsername() + " " + customer.getPassword()+ "" );
}
tx.commit();
session.close();
sf.close();
return list;
}
这是po
package ADO;
public class Customer {
private String id;
private String username;
private String password;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
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;
}
}
