需求背景
用若依搭建的后台管理环境，但是前台用户系统（前端）并没有和若依的前端集成在一起。是两个独立的前端项目，但是后端是集成在一起的。
我现在有一个前端会员表，若依有个系统用户表，如果想要会员登录（前台用户系统）和后台登录（后台管理系统）互不干扰怎么实现（两个登录接口）？
若依分离版使用的是sping security框架，所以本质上是sping security如何实现多用户！如果你已经具备springsecurity的知识，那么你会更轻松！
明确步骤
准备：准备自定义的用户实体类，强烈建议放在common中！
1、登录时查询我们自己的表，缓存用户信息时缓存我们用户实体类型：
实现UserDetailsService接口；
改造loginuser类；
自己声明AuthenticationManager 的bean；
2、自定义登录接口：
使用我们自定义的AuthenticationManager
3、从token能够获取登录人的信息
4、前端携带token
前期准备
准备一个我们自己的用户表实体类，假设叫做CustomerUser，这个实体类再多个模块中使用，强烈建议放在common模块中！
实现UserDetailsService接口
熟悉springsecurity的都知道，登录时查询用户表是依靠UserDetailsService接口实现的，我们想要登录时查询我们自己的会员表的话，就需要实现这个接口，参照若依的UserDetailsServiceImpl，我们假定他叫CustomerDetailsServiceImpl（请定义在framework模块！建议参考若依的userSetailServiceImpl的位置）
代码如下
package com.ruoyi.framework.web.service;import com.ruoyi.common.core.domain.entity.CustomerUser;
import com.ruoyi.common.core.domain.model.LoginUser;
import com.ruoyi.common.enums.UserStatus;
import com.ruoyi.common.exception.ServiceException;
import com.ruoyi.common.utils.MessageUtils;
import com.ruoyi.common.utils.StringUtils;
import com.ruoyi.customer.mapper.CustomerUserMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Component;/*** 用户验证处理** @author ruoyi*/
@Component("CustomerDetailsServiceImpl")
public class CustomerDetailsServiceImpl implements UserDetailsService
{private static final Logger log = LoggerFactory.getLogger(CustomerDetailsServiceImpl.class);@Autowiredprivate CustomerUserMapper customerUserMapper;@Autowiredprivate CustomerPasswordService customerPasswordService;@Overridepublic UserDetails loadUserByUsername(String username) throws UsernameNotFoundException{CustomerUser user = customerUserMapper.selectUserByUserName(username);if (StringUtils.isNull(user)){log.info("登录用户：{} 不存在.", username);throw new ServiceException(MessageUtils.message("user.not.exists"));}else if (UserStatus.DELETED.getCode().equals(user.getDelFlag())){log.info("登录用户：{} 已被删除.", username);throw new ServiceException(MessageUtils.message("user.password.delete"));}else if (UserStatus.DISABLE.getCode().equals(user.getActive())){log.info("登录用户：{} 已被停用.", username);throw new ServiceException(MessageUtils.message("user.blocked"));}customerPasswordService.validate(user);return createLoginUser(user);}public UserDetails createLoginUser(CustomerUser user){return new LoginUser(user.getUserId(), user);}
}
改造loginUser
新增一个属性，CustomerUser
代码如下
package com.ruoyi.common.core.domain.model;import com.alibaba.fastjson2.annotation.JSONField;
import com.ruoyi.common.core.domain.entity.SysUser;
import com.ruoyi.common.core.domain.entity.CustomerUser;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import java.util.Collection;
import java.util.Set;/*** 登录用户身份权限* * @author ruoyi*/
public class LoginUser implements UserDetails
{private static final long serialVersionUID = 1L;/*** 用户ID*/private Long userId;/*** 邀请用户ID*/private Long inviteId;/*** 部门ID*/private Long deptId;/*** 用户唯一标识*/private String token;/*** 登录时间*/private Long loginTime;/*** 过期时间*/private Long expireTime;/*** 登录IP地址*/private String ipaddr;/*** 登录地点*/private String loginLocation;/*** 浏览器类型*/private String browser;/*** 操作系统*/private String os;/*** 权限列表*/private Set<String> permissions;/*** 用户信息*/private SysUser user;/*** 客户信息*/private CustomerUser customerUser;public LoginUser(){}public LoginUser(SysUser user, Set<String> permissions){this.user = user;this.permissions = permissions;}public LoginUser(Long userId, Long deptId, SysUser user, Set<String> permissions){this.userId = userId;this.deptId = deptId;this.user = user;this.permissions = permissions;}public LoginUser(Long userId, CustomerUser user){this.userId = userId;this.customerUser = user;}public Long getUserId() { return userId; }public void setUserId(Long userId){this.userId = userId;}public Long getInviteId() { return inviteId; }public void setInviteId(Long inviteId){this.inviteId = inviteId;}public Long getDeptId(){return deptId;}public void setDeptId(Long deptId){this.deptId = deptId;}public String getToken(){return token;}public void setToken(String token){this.token = token;}@JSONField(serialize = false)@Overridepublic String getPassword(){if(user != null){return user.getPassword();}else{return customerUser.getPassword();}}@Overridepublic String getUsername(){if(user != null){return user.getUserName();}else{return customerUser.getUserName();}}/*** 账户是否未过期,过期无法验证*/@JSONField(serialize = false)@Overridepublic boolean isAccountNonExpired(){return true;}/*** 指定用户是否解锁,锁定的用户无法进行身份验证* * @return*/@JSONField(serialize = false)@Overridepublic boolean isAccountNonLocked(){return true;}/*** 指示是否已过期的用户的凭据(密码),过期的凭据防止认证* * @return*/@JSONField(serialize = false)@Overridepublic boolean isCredentialsNonExpired(){return true;}/*** 是否可用 ,禁用的用户不能身份验证* * @return*/@JSONField(serialize = false)@Overridepublic boolean isEnabled(){return true;}public Long getLoginTime(){return loginTime;}public void setLoginTime(Long loginTime){this.loginTime = loginTime;}public String getIpaddr(){return ipaddr;}public void setIpaddr(String ipaddr){this.ipaddr = ipaddr;}public String getLoginLocation(){return loginLocation;}public void setLoginLocation(String loginLocation){this.loginLocation = loginLocation;}public String getBrowser(){return browser;}public void setBrowser(String browser){this.browser = browser;}public String getOs(){return os;}public void setOs(String os){this.os = os;}public Long getExpireTime(){return expireTime;}public void setExpireTime(Long expireTime){this.expireTime = expireTime;}public Set<String> getPermissions(){return permissions;}public void setPermissions(Set<String> permissions){this.permissions = permissions;}public SysUser getUser(){ return user; }public void setUser(SysUser user){this.user = user;}public CustomerUser getCustomerUser(){ return customerUser; }public void setCustomerUser(CustomerUser customerUser) { this.customerUser = customerUser; }@Overridepublic Collection<? extends GrantedAuthority> getAuthorities(){return null;}
}
声明自定义AuthenticationManager 的bean
原因
是这个authenticationManager调用的是若依定义的UserDetailsServiceImpl而不是我们定义的CustomerDetailsServiceImpl ，那我们怎么样才能让他调用我们定义的CustomerDetailsServiceImpl 呢？其中关键的是authenticationManager，他决定了调用哪一个
一看@Resource就知道，他注入了一个bean！那他肯定声明了这个bean！我们要找到这个AuthenticationManager的bean声明
这个AuthenticationManager用的就是若依定义的userDetailsService！

}
自定义登录接口
上面我们自定义了一个AuthenticationManager，并且这个AuthenticationManager指向的是我们自己的CustomerDetailsService。那我们就需要在使用这个AuthenticationManager。
