ssh2怎样在jsp页面显示在数据库中查询到的数据

Answer 1

java从数据库中读取的数据显示在jsp的网页当中的方法是迭代table。
1、迭代数据的jsp页面代码：

<table>
<tr>
<th>Name</th>
<th>Email</th>
<th>Address</th>
<th>Phone No</th>
</tr>
<s:iterator value="users">
<tr>
<td><s:property value="name"/></td>
<td><s:property value="email"/></td>
<td><s:property value="address"/></td>
<td><s:property value="phno"/></td>
</tr>
</s:iterator>
</table>
2。后台java查询数据
public class RegisterAction extends ActionSupport{
String name,pwd,email,address;
int phno;

public RegisterAction() {}

List<User> users = new ArrayList<User>();
UserDao udao = new UserDao();

//Getters and setters.

public String execute() throws Exception {
User u=new User();
u.setName(name);
u.setEmail(email);
u.setAddress(address);
u.setPhno(phno);
u.setPwd(pwd);
udao.addUser(u);
return "success";
}

public String listAllUsers(){
users = udao.getUsers();
System.out.println("In Action, "+users);
return "success";
}
}
