java - 比较Jhipster中的两个集合

我需要找出为什么Java包含或等于方法在我的jhipster项目中不起作用？这在UserResource.java中

SecurityContextHolder.getContext().getAuthentication().getAuthorities().contains(AuthoritiesConstants.ADMIN_N);

为此，它返回false甚至SecurityContextHolder.getContext().getAuthentication().getAuthorities()= [ROLE_ADMIN]和AuthoritiesConstants.ADMIN_N=[ROLE_ADMIN]。方法equals也无效。那么正确的方法是什么？我的jhipster版本是4.8.2。

public final class AuthoritiesConstants {

public static final String ADMIN = "ROLE_ADMIN";

public static final String ADMIN_N = "[ROLE_ADMIN]";

}

最佳答案

您可以尝试以下两种方法:

SecurityContextHolderAwareRequestWrapper.isUserInRole(AuthoritiesConstants.ADMIN)

和:

Collection<? extends GrantedAuthority> authorities = SecurityContextHolder.getContext().getAuthentication().getAu‌​thorities();
boolean hasRoleAdmin = authorities.contains(new SimpleGrantedAuthority(AuthoritiesConstants.ADMIN));
