要在Apache Tomee和GemFire之间集成会话管理，可以使用Apache Shiro作为安全框架，并使用GemFire作为会话存储。

以下是一个简单的示例代码，演示了如何在Apache Tomee中集成Apache Shiro和GemFire：

1. 首先，您需要在pom.xml文件中添加以下依赖项：

    org.apache.shiro
    shiro-core
    1.7.1


    org.apache.shiro
    shiro-web
    1.7.1


    org.apache.shiro
    shiro-gemfire
    1.7.1


    io.pivotal.gemfire
    gemfire
    9.8.6

2. 创建一个GemFire会话管理器类，实现org.apache.shiro.session.mgt.SessionManager接口：

import org.apache.shiro.session.Session;
import org.apache.shiro.session.mgt.SessionContext;
import org.apache.shiro.session.mgt.SessionManager;
import org.apache.shiro.session.mgt.eis.AbstractSessionDAO;
import org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO;

public class GemFireSessionManager extends AbstractSessionDAO implements SessionManager {

    private EnterpriseCacheSessionDAO sessionDAO;

    public GemFireSessionManager() {
        this.sessionDAO = new EnterpriseCacheSessionDAO();
    }

    @Override
    public Session start(SessionContext sessionContext) {
        return sessionDAO.create(sessionContext);
    }

    @Override
    public Session getSession(SessionKey sessionKey) {
        return sessionDAO.readSession(sessionKey);
    }

    @Override
    public void update(Session session) {
        sessionDAO.update(session);
    }

    @Override
    public void delete(Session session) {
        sessionDAO.delete(session);
    }
}

3. 创建一个Shiro配置类，配置GemFire作为会话管理器：

import org.apache.shiro.cache.MemoryConstrainedCacheManager;
import org.apache.shiro.session.mgt.SessionManager;
import org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.apache.shiro.web.mgt.WebSecurityManager;
import org.apache.shiro.web.servlet.AbstractShiroFilter;
import org.apache.shiro.web.servlet.ShiroFilterFactoryBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ShiroConfig {

    @Bean
    public AbstractShiroFilter shiroFilterFactoryBean() throws Exception {
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(securityManager());
        shiroFilterFactoryBean.setLoginUrl("/login");
        shiroFilterFactoryBean.setSuccessUrl("/home");
        shiroFilterFactoryBean.setUnauthorizedUrl("/unauthorized");

        return shiroFilterFactoryBean;
    }

    @Bean
    public WebSecurityManager securityManager() {
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setSessionManager(sessionManager());
        securityManager.setCacheManager(new MemoryConstrainedCacheManager());

        return securityManager;
    }

    @Bean
    public SessionManager sessionManager() {
        GemFireSessionManager sessionManager = new GemFireSessionManager();
        sessionManager.setSessionDAO(new EnterpriseCacheSessionDAO());

        return sessionManager;
    }
}

4. 创建一个控制器类，用于处理登录和注销请求：

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;

@Controller
public class LoginController {

    @GetMapping("/login")
    public String login() {
        return "login";
    }

    @PostMapping("/login")
    public String doLogin(@RequestParam("username") String username,
                          @RequestParam("password") String password,
                          Model model) {
        Subject currentUser = SecurityUtils.getSubject();
        if (!currentUser.isAuthenticated()) {
            UsernamePasswordToken token = new UsernamePasswordToken(username, password);
            token.setRememberMe(true);
            try {
                currentUser.login(token);
            } catch (Exception e) {
                model.addAttribute
