我的系统里有两种用户，对应数据库两张表，所以必须自定义provider 和 AuthenticationToken，这样才能走到匹配自定义的UserDetailsService。
必须自定义原因在于，security内部是遍历prodvider，根据其support 方法判断是否匹配Controller提交的token，然后走provider注入的认证service方法。
security内部认证流程是这样的
1、 Controller
用用户名和密码构造AuthenticationToken 并提交给 authenticationManager，
authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password));2、spring security
会遍历自定义和内置provider，根据provider的support方法判断入参Token所匹配provider
public boolean supports(Class<?> authentication) {
return (EcStaffUsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication));
}3、调用匹配的provider内部认证逻辑
过程中会调用UserDetailsService.loadUserByUsername，这个service可以在SecurityConfig中配置注入到provider
4、UserDetailsService
需要我们自己查询数据库中用户对象，返回对象UserDetails，
我返回的是LoginUser （ implements UserDetails ），这样把数据库查出来用户对象加进去，方便前台Controller使用
@Override
public UserDetails loadUserByUsername(String username) //查询数据库5、继续走spring security内部逻辑
包括判断密码是否匹配等，如果密码不匹配或帐号过期等spring会上抛异常到Controller
6、所有调用完毕就会
回到Controller的方法，并返回authentication。对于异常需要自己捕获，详情可参见后面的代码。
authentication = authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(username, password));
LoginUser loginUser = (LoginUser) authentication.getPrincipal();说明：
大部分人是在流程最前面使用filter实现各种校验，而我的项目全部是前后端分离，所以我的filter只校验token有效性，我把各种非空校验放在controller。
1、基础配置-SecurityConfig
@Autowired
@Qualifier("userDetailsServiceImpl")
private UserDetailsService userDetailsService;
@Autowired
@Qualifier("ecStaffDetailsServiceImpl")
private UserDetailsService ecStaffDetailsServiceImpl;
@Autowired
private JwtAuthenticationTokenFilter authenticationTokenFilter;
@Bean
@Override
public AuthenticationManager authenticationManagerBean() throws Exception
{
return super.authenticationManagerBean();
}
@Override
protected void configure(HttpSecurity httpSecurity) throws Exception
{
httpSecurity
// CRSF禁用，因为不使用session
.csrf().disable()
// 认证失败处理类
.exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
// 基于token，所以不需要session
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
// 过滤请求
.authorizeRequests()
// 对于登录login 验证码captchaImage 允许匿名访问
.antMatchers("/login", "/captchaImage", "/store-api/ecommerce/login*.html",
"*.css",
"*.js"
).permitAll()
.antMatchers("/profileapi-docs").anonymous()
.antMatchers("/druid
@Bean
public BCryptPasswordEncoder bCryptPasswordEncoder()
{
return new BCryptPasswordEncoder();
}
@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception
{
//自定义provider及service，一套身份认证
auth.authenticationProvider(getEcStaffUsernamePasswordAuthenticationProvider())
//使用系统自带provider，及自定义service，另一套认证
.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder());
}
public EcStaffUsernamePasswordAuthenticationProvider getEcStaffUsernamePasswordAuthenticationProvider() {
EcStaffUsernamePasswordAuthenticationProvider provider = new EcStaffUsernamePasswordAuthenticationProvider();
provider.setPasswordEncoder(bCryptPasswordEncoder());
provider.setUserDetailsService(ecStaffDetailsServiceImpl);
return provider;
}2、基础配置-自定义AuthenticationToken
import org.springframework.security.authentication.UsernamePasswordAuthenticationToken;
public class EcStaffUsernamePasswordAuthenticationToken extends UsernamePasswordAuthenticationToken{
public EcStaffUsernamePasswordAuthenticationToken(Object principal, Object credentials) {
super(principal, credentials);
}
private static final long serialVersionUID = 8665690993060353849L;
}3、基础配置-自定义provider
import org.springframework.security.authentication.dao.DaoAuthenticationProvider;
import com.ruoyi.framework.security.authToken.EcStaffUsernamePasswordAuthenticationToken;
public class EcStaffUsernamePasswordAuthenticationProvider extends DaoAuthenticationProvider{
public boolean supports(Class<?> authentication) {
return (EcStaffUsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication));
}
}4、Controller发起身份认证
// 用户验证
Authentication authentication = null;
try
{
// 该方法会去调用EcStaffDetailsServiceImpl.loadUserByUsername
// 因为这个自定token只被自定provider的support所支持
// 所以才会provider中注入的EcStaffDetailsServiceImpl，在security配置文件注入的
authentication = authenticationManager.authenticate(new EcStaffUsernamePasswordAuthenticationToken(username, password));
}
catch (Exception e)
{
if (e instanceof BadCredentialsException)
{
//密码不匹配，需自定义返回前台消息
throw new UserPasswordNotMatchException();
}
else
{
throw new CustomException(e.getMessage());
}
}
//登录成功
LoginUser loginUser = (LoginUser) authentication.getPrincipal();5、service查询数据库中用户对象
import java.util.HashSet;
import java.util.Set;
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.stereotype.Service;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.ruoyi.common.constant.Constants;
import com.ruoyi.common.exception.BaseException;
import com.ruoyi.common.utils.MessageUtils;
import com.ruoyi.common.utils.StringUtils;
import com.ruoyi.ecommerce.constant.StaffStatusConstant;
import com.ruoyi.ecommerce.domain.EcStaff;
import com.ruoyi.ecommerce.service.IEcStaffService;
import com.ruoyi.framework.security.LoginUser;
@Service
public class EcStaffDetailsServiceImpl implements UserDetailsService
{
private static final Logger log = LoggerFactory.getLogger(EcStaffDetailsServiceImpl.class);
@Autowired
private IEcStaffService ecStaffService;
@Autowired
private SysPermissionService permissionService;
@Override
public UserDetails loadUserByUsername(String username)
{
QueryWrapper<EcStaff> queryWrapper = new QueryWrapper<>();
queryWrapper.eq("phone", username);
EcStaff user = ecStaffService.getOne(queryWrapper);
if (StringUtils.isNull(user))
{
log.info("登录用户：{} 不存在.", username);
throw new BaseException(MessageUtils.message("user.not.exists"));
}
else if (Constants.DELETED.equals(user.getDeleted()))
{
log.info("登录用户：{} 已被删除.", username);
throw new BaseException(MessageUtils.message("user.password.delete"));
}
return createLoginUser(user);
}
public UserDetails createLoginUser(EcStaff user)
{
return new LoginUser(user, permissionService.getMenuPermission(user));
}
}6、service返回的LoginUser
因为有两种用户sysuser和ecstaff，为了基于这个LoginUser统一提供getUsername方法，让他们继承或实现统一BaseUser，
可以不统一封装因为LoginUser构造方法入参是object , 即LoginUser(Object user, Set<String> permissions)
import java.util.Collection;
import java.util.Set;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.ruoyi.ecommerce.domain.BaseUser;
public class LoginUser implements UserDetails
{
private static final long serialVersionUID = 1L;
private String token;
private Long loginTime;
private Long expireTime;
private String ipaddr;
private String loginLocation;
private String browser;
private String os;
private Set<String> permissions;
private Object user;
private Class userClass;
public String getToken()
{
return token;
}
public void setToken(String token)
{
this.token = token;
}
public LoginUser()
{
}
public LoginUser(Object user, Set<String> permissions)
{
this.userClass = user.getClass();
this.user = user;
this.permissions = permissions;
}
@JsonIgnore
@Override
public String getPassword()
{
return ((BaseUser)user).getPassword();
}
@Override
public String getUsername()
{
return ((BaseUser)user).getUserName();
}
@JsonIgnore
@Override
public boolean isAccountNonExpired()
{
return true;
}
@JsonIgnore
@Override
public boolean isAccountNonLocked()
{
return true;
}
@JsonIgnore
@Override
public boolean isCredentialsNonExpired()
{
return true;
}
@JsonIgnore
@Override
public 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 Object getUser()
{
return user;
}
public void setUser(Object user)
{
this.user = user;
}
public Class getUserClass() {
return userClass;
}
public void setUserClass(Class userClass) {
this.userClass = userClass;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities()
{
return null;
}
}7、另一套用户controller登录认证方法
注意这里换了security提供的AuthToken，这个token会调用security内部的DaoAuthenticationProvider进行认证
// 用户验证
Authentication authentication = null;
try
{
// 该方法会去调用UserDetailsServiceImpl.loadUserByUsername
// 该方式使用的security内置token会使用内置DaoAuthenticationProvider认证
// UserDetailsServiceImpl是在security config中配置的
authentication = authenticationManager
.authenticate(new UsernamePasswordAuthenticationToken(username, password));
}
catch (Exception e)
{
if (e instanceof BadCredentialsException)
{
throw new UserPasswordNotMatchException();
}
else
{
throw new CustomException(e.getMessage());
}
}
LoginUser loginUser = (LoginUser) authentication.getPrincipal();// 该方法会去调用8、另一套用户service
可参照上述service写，查询另一张用户表即可，返回UserDetails
以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
