Spring Oauth2 - 重新加载校长

Question

我已经使用spring安全模块实现了OAuth2密码授权.我添加了自己的UserDetails实现和UserDetailsS​​ervice(jdbc).我将用户注入我的控制器:

@AuthenticationPrincipal User user

User是UserDetails的实现.现在我想添加更改用户数据的可能性而不刷新令牌.

我尝试用以下内容刷新主体:

User updatedUser = ...
Authentication newAuth = new UsernamePasswordAuthenticationToken(updatedUser, updatedUser.getPassword(), updatedUser.getAuthorities());
SecurityContextHolder.getContext().setAuthentication(newAuth);

但它不起作用,当我调用另一个控制器方法时,它返回旧的User对象.

有没有办法在没有刷新令牌的情况下更改用户数据？是否有任何解决方案使Spring安全性始终从数据库(而不是从Cache)加载用户数据？

Answer 1

我从这个答案中找到了实现这一目标的方法。我创建HttpSessionSecurityContextRepository

@Bean
public ReloadUserPerRequestHttpSessionSecurityContextRepository userDetailContextRepository() {
    return new ReloadUserPerRequestHttpSessionSecurityContextRepository();
}

并将其添加到我的asHttpSecurity类中WebSecurityConfigurerAdapter

    .and()
        .csrf()
            .csrfTokenRepository(csrfTokenRepository())
    .and()
        .securityContext()
            .securityContextRepository(userDetailContextRepository())

以下是在每次请求时获取更新的用户信息的示例代码。您可以从 API 服务器或user-info-urloauth2 配置中获取。

public class ReloadUserPerRequestHttpSessionSecurityContextRepository extends HttpSessionSecurityContextRepository {

    @Override
    public SecurityContext loadContext(HttpRequestResponseHolder requestResponseHolder) {
        SecurityContext context = super.loadContext(requestResponseHolder);

        Authentication auth = context.getAuthentication();
        if (auth != null && auth instanceof OAuth2Authentication) {
            OAuth2Authentication oldAuth = (OAuth2Authentication) auth;
            if (oldAuth.getPrincipal() instanceof LinkedHashMap) {
                createNewUserDetailsFromPrincipal(oldAuth.getPrincipal());
            }
            context.setAuthentication(oldAuth);
        }
        return context;
    }

    @SuppressWarnings("unchecked")
    private void createNewUserDetailsFromPrincipal(Object principal) {
        LinkedHashMap<String, Object> userDetailInfo = (LinkedHashMap<String, Object>) principal;
        // fetch User informations from your API server or your database or
        // 'user-info-url' of oauth2 endpoint
        userDetailInfo.put("name", "EDITED_USER_NAME");
    }

}
