Spring Boot通过Controller从Authentication获取用户名

【中文标题】Spring Boot通过Controller从Authentication获取用户名【英文标题】:Springboot get username from Authentication via Controller 【发布时间】:2018-09-06 20:36:24 【问题描述】:问题: 我想仅从 authenticate.getName()... 获取/提取用户名/电子邮件,如果可能,而不是使用解析字符串。
authentication.getName() 或 principal.getName() 值:
[username]: org.springframework.security.core.userdetails.User@21463e7a: Username: butitoy@iyotbihagay.com; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Not granted any authorities
在本例中,我只想获取用户名的值,即 butitoy@iyotbihagay.com
解决方案:
由于我只想获取用户名/电子邮件 (butitoy@iyotbihagay.com),并且它返回整个主要内容/文本(上图),因此我将我在主题中设置的值替换为主要值.. . 到电子邮件值.. 它现在可以工作了。
@Override
protected void successfulAuthentication(HttpServletRequest req,
HttpServletResponse res,
FilterChain chain,
Authentication auth) throws IOException, ServletException
String email = auth.getName();
String principal = auth.getPrincipal().toString();
Date expiration = new Date(System.currentTimeMillis() + SecurityConstants.EXPIRATION_TIME);
String token = Jwts.builder()
.setSubject(email) //from principal to email
.setExpiration(expiration)
.signWith(SignatureAlgorithm.HS512, SecurityConstants.SECRET.getBytes())
.compact();
AuthenticatedUser loginUser = new AuthenticatedUser(email);
loginUser.setToken(token);
String jsonUser = Util.objectToJsonResponseAsString(loginUser, "user");
res.addHeader(SecurityConstants.HEADER_STRING, SecurityConstants.TOKEN_PREFIX + token);
res.setContentType("application/json");
res.setCharacterEncoding(ConstantUtil.DEFAULT_ENCODING);
res.getWriter().write(jsonUser);
我现在可以使用不同的方式获取用户名/电子邮件值,例如你们建议的方式……甚至是我目前使用的方式。我现在不需要任何特殊的解析来从 Authentication 对象中获取电子邮件值。
在我之前使用 Spring 的非 RESTful 应用程序中...我可以使用控制器方法参数中注入的 Authentication 类轻松获取用户名。
控制器:
...
public Ticket getBySwertresNo(Authentication authentication, @PathVariable String swertresNo)
logger.debug("Inside getBySwertresNo: " + swertresNo);
System.out.println("\n[username]: " + authentication.getName() + "\n");
return m_sugalService.getSwertresInfoBySwertresNo(swertresNo);
...
控制台:
[username]: butitoy@iyotbihagay.com
现在,在我当前的项目中……我使用了 RESTful 方法,在成功验证后,我返回了一个令牌,该令牌将在请求标头中使用/注入。我可以使用令牌登录...但是当我获得 authentication.getName() 的值时...返回的不仅仅是电子邮件地址,它还包含一些其他信息。
控制台(REST + JWT):
[username]: org.springframework.security.core.userdetails.User@21463e7a: Username: butitoy@iyotbihagay.com; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Not granted any authorities
我只想获取用户名值“butitoy@iyotbihagay.com”。
JWT 身份验证过滤器:
public class JWTAuthenticationFilter extends UsernamePasswordAuthenticationFilter
private AuthenticationManager authenticationManager;
public JWTAuthenticationFilter(AuthenticationManager authenticationManager)
this.authenticationManager = authenticationManager;
@Override
public Authentication attemptAuthentication(HttpServletRequest req,
HttpServletResponse res) throws AuthenticationException
String username = req.getParameter("username");
String password = req.getParameter("password");
UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username, password);
Authentication authentication = authenticationManager.authenticate(authenticationToken);
return authentication;
@Override
protected void successfulAuthentication(HttpServletRequest req,
HttpServletResponse res,
FilterChain chain,
Authentication auth) throws IOException, ServletException
String email = auth.getName();
String principal = auth.getPrincipal().toString();
Date expiration = new Date(System.currentTimeMillis() + SecurityConstants.EXPIRATION_TIME);
String token = Jwts.builder()
.setSubject(principal)
.setExpiration(expiration)
.signWith(SignatureAlgorithm.HS512, SecurityConstants.SECRET.getBytes())
.compact();
AuthenticatedUser loginUser = new AuthenticatedUser(email);
loginUser.setToken(token);
String jsonUser = Util.objectToJsonResponseAsString(loginUser, "user");
res.addHeader(SecurityConstants.HEADER_STRING, SecurityConstants.TOKEN_PREFIX + token);
res.setContentType("application/json");
res.setCharacterEncoding(ConstantUtil.DEFAULT_ENCODING);
res.getWriter().write(jsonUser);
JWT 授权过滤器:
public class JWTAuthorizationFilter extends BasicAuthenticationFilter
public JWTAuthorizationFilter(AuthenticationManager authManager)
super(authManager);
@Override
protected void doFilterInternal(HttpServletRequest req,
HttpServletResponse res,
FilterChain chain) throws IOException, ServletException
String header = req.getHeader(SecurityConstants.HEADER_STRING);
if (header == null || !header.startsWith(SecurityConstants.TOKEN_PREFIX))
chain.doFilter(req, res);
return;
UsernamePasswordAuthenticationToken authentication = getAuthentication(req);
SecurityContextHolder.getContext().setAuthentication(authentication);
chain.doFilter(req, res);
private UsernamePasswordAuthenticationToken getAuthentication(HttpServletRequest request)
String token = request.getHeader(SecurityConstants.HEADER_STRING);
if (token != null)
// parse the token.
String user = Jwts.parser()
.setSigningKey(SecurityConstants.SECRET.getBytes())
.parseClaimsJws(token.replace(SecurityConstants.TOKEN_PREFIX, ""))
.getBody()
.getSubject();
if (user != null)
return new UsernamePasswordAuthenticationToken(user, null, new ArrayList<>());
return null;
return null;
【问题讨论】:
为什么不在控制器中设置断点并检查 Authentication 对象的值? 只是想指出,RESTful 与你是否使用 JWT 无关。 感谢您的注意,顺便说一句,我是 REST 新手。我尝试调试控制器,但得到的是整个长字符串值,而不是分隔字符串。 你得到了整个对象,因为这就是你传递给的内容:String token = Jwts.builder().setSubject(principal)。您可以将其更改为使用电子邮件,或者只使用用户名,然后稍后为该用户进行查找。 @BorgyManotoy 对此有何更新? 【参考方案1】:我认为您可以在Authentication
和Principal
类型的注入控制器参数中使用authentication.getName
和principal.getName
:
@Controller
@RequestMapping("/info")
public class GetNameController
@RequestMapping(value = "/name", method = RequestMethod.GET)
public String getName(Authentication authentication, Principal principal)
System.out.println(authentication.getName());
System.out.println("-----------------");
System.out.println(principal.getName());
return "";
可以生产
admin

admin

相同结果:org.springframework.security.core.userdetails.User@21463e7a:用户名:butitoy@iyotbihagay.com;密码保护];启用:真; AccountNonExpired:真;凭据非过期:真; AccountNonLocked:真;未授予任何权限【参考方案2】:就 Authentication/Principal 对象而言,使用令牌还是基本 spring 安全认证都没有关系。
在 Spring Security 的情况下,您可以通过 获取当前登录用户
1.Object user = Authentication authentication
(正如你已经在做的那样)
2.
Object user = SecurityContextHolder.getContext().getAuthentication()
.getPrincipal();
在这两种情况下,user
将包含您从UserDetailsService.loadUserByUsername(...)
返回的用户对象。所以使用默认的UserDetailsService
,你会得到spring security的User
对象,其中包含username
、password
等基本用户信息。
因此,如果您使用默认 spring 的 UserDetailsService
,那么您可以通过以下方式获取当前登录用户
UserDetails userDetails = (UserDetails) SecurityContextHolder.getContext().getAuthentication()
.getPrincipal();
String username = userDetails.getUsername();
【讨论】:
无法投射到用户【参考方案3】:你可以使用
导入 org.springframework.security.core.Authentication;
导入 org.springframework.security.core.context.SecurityContextHolder;
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
System.out.println("--------------------------------------------------------------");
JwtUser jwtUser = (JwtUser) auth.getPrincipal();
//Get the username of the logged in user: getPrincipal()
System.out.println("auth.getPrincipal()=>"+jwtUser.getUsername() );
//Get the password of the authenticated user: getCredentials()
System.out.println("auth.getCredentials()=>"+auth.getCredentials());
//Get the assigned roles of the authenticated user: getAuthorities()
System.out.println("auth.getAuthorities()=>"+auth.getAuthorities());
//Get further details of the authenticated user: getDetails()
System.out.println("auth.getDetails()=>"+auth.getDetails());
System.out.println("--------------------------------------------------------------");

【参考方案4】:到目前为止还没有看到任何公认的答案,也许这会有所帮助:
使用JwtTokenUtils.debugPrint();
从下面的类中调用。对于其他令牌有效负载,请参阅 tokenMap
中可用的内容。

HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
return request.getHeader("Authorization");
private static Map<String, Object> decode(String token)
try
