使用Spring Boot ；/春季安全

我想使用权限、作用域或类似的权限来允许细粒度地访问REST资源

理想情况下，我想做以下事情：

@PreAuthorize("hasPermission('Brands', 'brands:write')")
ResponseEntity<Brand> getBrand(@PathVariable("brandCode") String brandCode);

我已经看过政策执行者，我不清楚它到底应该如何使用

我可以编写以下表格的代码：

KeycloakSecurityContext keycloakSecurityContext = (KeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());
AuthorizationContext authzContext = keycloakSecurityContext.getAuthorizationContext();
if (authzContext.hasScopePermission("brands:write")) {

// This works....
}

如何将PolicyEnforcing中的AuthorizationContext与标准的Spring安全注释联系起来

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {
@Autowired
private HttpServletRequest request;


@Override
public boolean hasPermission(Authentication auth, Object targetDomainObject, Object permission) {
    if ((auth == null) || (targetDomainObject == null) || !(permission instanceof String)){
        return false;
    }

    KeycloakSecurityContext keycloakSecurityContext = (KeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());
    AuthorizationContext authzContext = keycloakSecurityContext.getAuthorizationContext();

    if(targetDomainObject instanceof String) {
        return authzContext.hasPermission((String)targetDomainObject, (String)permission);
    } else if(targetDomainObject == null) {
        return authzContext.hasScopePermission((String)permission);
    } else {
        return false;
    }
}

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {
@Autowired
private HttpServletRequest request;


@Override
public boolean hasPermission(Authentication auth, Object targetDomainObject, Object permission) {
    if ((auth == null) || (targetDomainObject == null) || !(permission instanceof String)){
        return false;
    }

    KeycloakSecurityContext keycloakSecurityContext = (KeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());
    AuthorizationContext authzContext = keycloakSecurityContext.getAuthorizationContext();

    if(targetDomainObject instanceof String) {
        return authzContext.hasPermission((String)targetDomainObject, (String)permission);
    } else if(targetDomainObject == null) {
        return authzContext.hasScopePermission((String)permission);
    } else {
        return false;
    }
}
