我对这个SessionInterceptor一无所知 的 SessionInterceptor.java
public class SessionInterceptor extends AbstractInterceptor {
private static final long serialVersionUID = 1L;
@Override
public String intercept(ActionInvocation invocation) throws Exception {
Map<String,Object> session = invocation.getInvocationContext().getSession();
if(session.isEmpty()){
System.out.println(session.containsKey("logged-in"));
return "success"; // session is empty/expired
}
return invocation.invoke();
}
}
最后,我的ActionClass。
LoginAction.java
public class LoginAction extends ActionSupport implements SessionAware{
private static final long serialVersionUID = 1L;
private String password;
private String username;
Map<String, Object> session;
public String login(){
try {
String sql = "SELECT UAFUSERID, UAFUSERTYPE, UAFACCNTSTATUS from USERACCOUNTFILE WHERE UAFUSERID='"+getUsername()+"' AND UAFPASSWORD='"+getPassword()+"'";
Class.forName("com.mysql.jdbc.Driver");
Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/ibmeaylportaldb", "root", "passw0rd");
Statement statement = connection.createStatement();
ResultSet rs = statement.executeQuery(sql);
System.out.println((rs!=null));
while(rs.next()){
if(rs.getString("UAFACCNTSTATUS").equals("DIS")){
return "disabled";
}
sql = "SELECT * from USERDETAILFILE WHERE UAFUSERID='"+getUsername()+"'";
statement = connection.createStatement();
ResultSet rsUser = statement.executeQuery(sql);
session.put("logged-in", new UserBean(rsUser.getString(1),rsUser.getString(2),rsUser.getString(3),
rsUser.getString(4),rsUser.getString(5),rsUser.getString(6),rs.getString("UAFUSERTYPE")));
if(rs.getString("UAFUSERTYPE").equals("TRNEE")){
return SUCCESS;
}
}
return ERROR;
} catch (Exception e) {
System.out.println(e.getMessage());
}
return ERROR;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Override
public void setSession(Map<String, Object> session) {
this.session = session;
}
}
我的问题是,我是否必须创建一个地图来保存所有用户会话以跟踪它们?我也希望当用户意外关闭浏览器时,在一定时间内,用户仍然可以访问应用程序而无需再次登录。
