Java 如何使用aop处理每个客户端的Wicket会话

我正在使用Wicket 1.4.9+Spring 3+iBatis。我想在使用之前获取会话数据，但我有一个大问题，因为这些数据放在Wicket web会话上（这些数据选择在登录页面上）

我正在使用SpringAOP进行点切割，但我无法为每个客户端进行点切割会话。如何解决这个问题

用户类实体

package com.app.entity;

import java.io.Serializable;
import java.util.Date;

public class User implements Serializable {

    private String name;
    private String lastname;
    private String username;
    private String password;
    private String crtUser;
    private Date crtDate;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getLastname() {
        return lastname;
    }

    public void setLastname(String lastname) {
        this.lastname = lastname;
    }

    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 getCrtUser() {
        return crtUser;
    }

    public void setCrtUser(String crtUser) {
        this.crtUser = crtUser;
    }

    public Date getCrtDate() {
        return crtDate;
    }

    public void setCrtDate(Date crtDate) {
        this.crtDate = crtDate;
    }

}

Web应用程序类

package com.app.conf;

import org.apache.wicket.Page;
import org.apache.wicket.Request;
import org.apache.wicket.Response;
import org.apache.wicket.Session;
import org.apache.wicket.protocol.http.WebApplication;
import org.apache.wicket.spring.injection.annot.SpringComponentInjector;

import com.app.page.UserLoginPage;

public class WebApp extends WebApplication {

    @Override
    protected void init() {
        addComponentInstantiationListener(new SpringComponentInjector(this));
    }

    @Override
    public Class<? extends Page> getHomePage() {
        return UserLoginPage.class;
    }

    @Override
    public Session newSession(Request request, Response response) {
        return new CustomSession(request);
    }

}

用户登录页面：登录时保持会话

package com.app.page;

import org.apache.wicket.ajax.AjaxRequestTarget;
import org.apache.wicket.ajax.markup.html.form.AjaxButton;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.form.Form;
import org.apache.wicket.markup.html.form.PasswordTextField;
import org.apache.wicket.markup.html.form.TextField;
import org.apache.wicket.model.PropertyModel;

import com.app.conf.CustomSession;
import com.app.entity.User;

public class UserLoginPage extends WebPage {

    private LoginForm form;

    public UserLoginPage() {
        form = new LoginForm("form");
        add(form);
    }

    private class LoginForm extends Form{

        private User user;

        private TextField<String> username;
        private PasswordTextField password;
        private AjaxButton submitButton;

        public LoginForm(String id) {
            super(id);

            user = new User();

            username = new TextField<String>("username",
                    new PropertyModel<String>(this, "user.username"));
            add(username);

            password = new PasswordTextField("password" , 
                    new PropertyModel<String>(this, "user.password"));
            add(password);

            submitButton = new AjaxButton("submitButton", this) {

                @Override
                protected void onSubmit(AjaxRequestTarget arg0, Form<?> arg1) {
                    getCustomSession().setUser(user);
                    setResponsePage(new UserAddPage());
                }
            };
            add(submitButton);
        }
    }

    public CustomSession getCustomSession(){
        return (CustomSession)getSession();
    }

}

WebApp.getSession（）.getUser（）

我可以想象，您希望在spring上下文中注册一个可以提供授权用户的bean。这可以从您的WebApp会话中检索用户（WebApp实例也将是一个已注册的bean，但我假设它已经注册）。spring文档/社区中应该有大量关于这个用例的信息

---

为了获得更好的答案，您应该清理您的问题（代码块的使用）并说明用例。

这很有趣，如果您提供更多信息，我将很乐意尝试一下。数据是什么，何时创建，何时创建会话，您需要它做什么。你为什么不展示一些到目前为止你已经尝试过的示例代码呢？帮帮我！为了解决这个问题
