Spring 如何在模拟其他用户后获取原始用户？

我使用spring提供的Switch用户过滤器来模拟用户

如何获取在SwitchUserFilter中模拟的原始用户

我正在采取的步骤：

前

现在我需要的是在swtichback时在过滤器中获取原始用户（User1）

有可能吗

请建议。 让我知道任何人需要更多的信息。请评论

提前感谢。

这是您访问原始用户的方式：

Collection<? extends GrantedAuthority> authorities = SecurityContextHolder.getContext().getAuthentication().getAuthorities();

for (GrantedAuthority grantedAuthority : authorities) {
    if (SwitchUserFilter.ROLE_PREVIOUS_ADMINISTRATOR.equals(grantedAuthority.getAuthority())) {
        System.out.println(((SwitchUserGrantedAuthority) grantedAuthority).getSource().getPrincipal());
    }
}

Collection在jhipster生成的应用程序中的UserJwTController中添加此自定义方法

@PostMapping("/authenticate-externalnodes")
    public ResponseEntity<JWTToken> authenticateExternalnodes(@Valid @RequestBody LoginVM loginVM) {
        // Get Roles for user via username
        Set<Authority> authorities = userService.getUserWithAuthoritiesByLogin(loginVM.getUsername()).get()
                .getAuthorities();
        // Create Granted Authority Rules
        Set<GrantedAuthority> grantedAuthorities = new HashSet<>();
        for (Authority authority : authorities) {
            grantedAuthorities.add(new SimpleGrantedAuthority(authority.getName()));
        }
        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(
                loginVM.getUsername(), "", grantedAuthorities);
        Authentication authentication = authenticationToken;
        SecurityContextHolder.getContext().setAuthentication(authentication);
        boolean rememberMe = (loginVM.isRememberMe() == null) ? false : loginVM.isRememberMe();
        String jwt = tokenProvider.createToken(authentication, rememberMe);
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.add(JWTFilter.AUTHORIZATION_HEADER, "Bearer " + jwt);
        return new ResponseEntity<>(new JWTToken(jwt), httpHeaders, HttpStatus.OK);
    }

@PostMapping（/authenticate externalnodes）
公共响应身份验证外部节点（@Valid@RequestBody LoginVM LoginVM）{
//通过用户名获取用户的角色
Set authorities=userService.getUserWithAuthoritiesByLogin（loginVM.getUsername（））.get（）
.getAuthorities（）；
//创建授权规则
Set grantedAuthories=new HashSet（）；
适用于（权限：权限）{
grantedAuthories.add（新的SimpleGrantedAuthority（authority.getName（））；
}
UsernamePasswordAuthenticationToken authenticationToken=新UsernamePasswordAuthenticationToken(
loginVM.getUsername（），“”，授权机构）；
身份验证=authenticationToken；
SecurityContextHolder.getContext（）.setAuthentication（身份验证）；
布尔rememberMe=（loginVM.isRememberMe（）==null）？false:loginVM.isRememberMe（）；
字符串jwt=tokenProvider.createToken（身份验证，rememberMe）；
HttpHeaders HttpHeaders=新的HttpHeaders（）；
httpHeaders.add（JWTFilter.AUTHORIZATION_头，“承载者”+jwt）；
返回新的ResponseEntity（新JWTToken（jwt）、httpHeaders、HttpStatus.OK）；
}
您能否分享一些示例代码，说明如何在步骤3中提到的过滤器中获取user2？当我从filter.setTargetUrl（）中设置的targetUrl中检查主体时，仍然得到user1。
@PostMapping("/authenticate-externalnodes")
    public ResponseEntity<JWTToken> authenticateExternalnodes(@Valid @RequestBody LoginVM loginVM) {
        // Get Roles for user via username
        Set<Authority> authorities = userService.getUserWithAuthoritiesByLogin(loginVM.getUsername()).get()
                .getAuthorities();
        // Create Granted Authority Rules
        Set<GrantedAuthority> grantedAuthorities = new HashSet<>();
        for (Authority authority : authorities) {
            grantedAuthorities.add(new SimpleGrantedAuthority(authority.getName()));
        }
        UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(
                loginVM.getUsername(), "", grantedAuthorities);
        Authentication authentication = authenticationToken;
        SecurityContextHolder.getContext().setAuthentication(authentication);
        boolean rememberMe = (loginVM.isRememberMe() == null) ? false : loginVM.isRememberMe();
        String jwt = tokenProvider.createToken(authentication, rememberMe);
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.add(JWTFilter.AUTHORIZATION_HEADER, "Bearer " + jwt);
        return new ResponseEntity<>(new JWTToken(jwt), httpHeaders, HttpStatus.OK);
    }
