若依一次会话用户数据存储过程

1.用户数据存储，在拦截器中进行用户数据效验时存入用户数据

package com.ruoyi.common.security.interceptor;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.method.HandlerMethod;
import org.springframework.web.servlet.AsyncHandlerInterceptor;
import com.ruoyi.common.core.constant.SecurityConstants;
import com.ruoyi.common.core.context.SecurityContextHolder;
import com.ruoyi.common.core.utils.ServletUtils;
import com.ruoyi.common.core.utils.StringUtils;
import com.ruoyi.common.security.auth.AuthUtil;
import com.ruoyi.common.security.utils.SecurityUtils;
import com.ruoyi.system.api.model.LoginUser;

/**
 * 自定义请求头拦截器，将Header数据封装到线程变量中方便获取
 * 注意：此拦截器会同时验证当前用户有效期自动刷新有效期
 *
 * @author ruoyi
 */
public class HeaderInterceptor implements AsyncHandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        if (!(handler instanceof HandlerMethod)) {
            return true;
        }
        /*拦截器注入用户数据*/
        SecurityContextHolder.setUserId(ServletUtils.getHeader(request, SecurityConstants.DETAILS_USER_ID));
        SecurityContextHolder.setUserName(ServletUtils.getHeader(request, SecurityConstants.DETAILS_USERNAME));
        SecurityContextHolder.setUserKey(ServletUtils.getHeader(request, SecurityConstants.USER_KEY));

        String token = SecurityUtils.getToken();
        if (StringUtils.isNotEmpty(token)) {
            LoginUser loginUser = AuthUtil.getLoginUser(token);
            if (StringUtils.isNotNull(loginUser)) {
                AuthUtil.verifyLoginUserExpire(loginUser);
                SecurityContextHolder.set(SecurityConstants.LOGIN_USER, loginUser);
            }
        }
        return true;
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        SecurityContextHolder.remove();
    }
}

2.用户数据获取

package com.ruoyi.common.security.utils;

import javax.servlet.http.HttpServletRequest;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import com.ruoyi.common.core.constant.SecurityConstants;
import com.ruoyi.common.core.constant.TokenConstants;
import com.ruoyi.common.core.context.SecurityContextHolder;
import com.ruoyi.common.core.utils.ServletUtils;
import com.ruoyi.common.core.utils.StringUtils;
import com.ruoyi.system.api.model.LoginUser;

/**
 * 权限获取工具类
 * 
 * @author ruoyi
 */
public class SecurityUtils
{
    /**
     * 获取用户ID
     */
    public static Long getUserId()
    {
        return SecurityContextHolder.getUserId();
    }

    /**
     * 获取用户名称
     */
    public static String getUsername()
    {
        return SecurityContextHolder.getUserName();
    }

    /**
     * 获取用户key
     */
    public static String getUserKey()
    {
        return SecurityContextHolder.getUserKey();
    }

    /**
     * 获取登录用户信息
     */
    public static LoginUser getLoginUser()
    {
        return SecurityContextHolder.get(SecurityConstants.LOGIN_USER, LoginUser.class);
    }

    /**
     * 获取请求token
     */
    public static String getToken()
    {
        return getToken(ServletUtils.getRequest());
    }

    /**
     * 根据request获取请求token
     */
    public static String getToken(HttpServletRequest request)
    {
        // 从header获取token标识
        String token = request.getHeader(TokenConstants.AUTHENTICATION);
        return replaceTokenPrefix(token);
    }

    /**
     * 裁剪token前缀
     */
    public static String replaceTokenPrefix(String token)
    {
        // 如果前端设置了令牌前缀，则裁剪掉前缀
        if (StringUtils.isNotEmpty(token) && token.startsWith(TokenConstants.PREFIX))
        {
            token = token.replaceFirst(TokenConstants.PREFIX, "");
        }
        return token;
    }

    /**
     * 是否为管理员
     * 
     * @param userId 用户ID
     * @return 结果
     */
    public static boolean isAdmin(Long userId)
    {
        return userId != null && 1L == userId;
    }

    /**
     * 生成BCryptPasswordEncoder密码
     *
     * @param password 密码
     * @return 加密字符串
     */
    public static String encryptPassword(String password)
    {
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        return passwordEncoder.encode(password);
    }

    /**
     * 判断密码是否相同
     *
     * @param rawPassword 真实密码
     * @param encodedPassword 加密后字符
     * @return 结果
     */
    public static boolean matchesPassword(String rawPassword, String encodedPassword)
    {
        BCryptPasswordEncoder passwordEncoder = new BCryptPasswordEncoder();
        return passwordEncoder.matches(rawPassword, encodedPassword);
    }
}

3.中间类

package com.ruoyi.common.core.context;

import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;
import com.alibaba.ttl.TransmittableThreadLocal;
import com.ruoyi.common.core.constant.SecurityConstants;
import com.ruoyi.common.core.text.Convert;
import com.ruoyi.common.core.utils.StringUtils;

/**
 * 获取当前线程变量中的 用户id、用户名称、Token等信息 
 * 注意： 必须在网关通过请求头的方法传入，同时在HeaderInterceptor拦截器设置值。 否则这里无法获取
 *
 * @author ruoyi
 */
public class SecurityContextHolder
{
    private static final TransmittableThreadLocal> THREAD_LOCAL = new TransmittableThreadLocal<>();

    public static void set(String key, Object value)
    {
        Map map = getLocalMap();
        map.put(key, value == null ? StringUtils.EMPTY : value);
    }

    public static String get(String key)
    {
        Map map = getLocalMap();
        return Convert.toStr(map.getOrDefault(key, StringUtils.EMPTY));
    }

    public static  T get(String key, Class clazz)
    {
        Map map = getLocalMap();
        return StringUtils.cast(map.getOrDefault(key, null));
    }

        }
        return map;
    }

    public static void setLocalMap(Map threadLocalMap)
    {
        THREAD_LOCAL.set(threadLocalMap);
    }

    public static Long getUserId()
    {
        return Convert.toLong(get(SecurityConstants.DETAILS_USER_ID), 0L);
    }

    public static void setUserId(String account)
    {
        set(SecurityConstants.DETAILS_USER_ID, account);
    }

    public static String getUserName()
    {
        return get(SecurityConstants.DETAILS_USERNAME);
    }

    public static void setUserName(String username)

    }

    }

    }

    public static void remove()
    {
        THREAD_LOCAL.remove();
    }
}
