java - #oauth2 方法级别的安全表达式

Question

我应该怎么做才能像下面的示例那样在方法级别使用#oauth2 安全表达式？

@RequestMapping(value = "email", method = RequestMethod.GET)
  @ResponseBody
  @PreAuthorize("#oauth2.hasScope('read')")
  public String email() {

    return "test@email.com";
  }

如果我对该资源发出请求，我会收到

    [INFO] java.lang.IllegalArgumentException: Failed to evaluate expression '#oauth2.hasScope('read')'
[INFO]  at org.springframework.security.access.expression.ExpressionUtils.evaluateAsBoolean(ExpressionUtils.java:14)

[INFO]  at pl.insert.controllers.ResourceController.email(ResourceController.java:22)

如果我在我的 ResourceServerConfiguration 而不是@Controllers 的方法中指定访问权限，同样的事情也很有效

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter {

  @Override
  public void configure(HttpSecurity http) throws Exception {
    http.requestMatchers().antMatchers("/oauth/resources/**");
    http.authorizeRequests().anyRequest().access("#oauth2.hasScope('read')");
  }
}

@PreAuthorize("permitAll") 或 @PreAuthorize("denyAll") 等标准安全表达式按预期工作。所以，可能我必须以某种方式告诉我的 AspectJMethodSecurityInterceptor 使用 OAuth2WebSecurityExpressionHandler。有任何想法吗？

Answer 1

要启用#oAuth2 安全表达式，只需将默认表达式处理程序设置为 OAuth2MethodSecurityExpressionHandler 而不是 DefaultMethodSecurityExpressionHandler。因为 OAuth2MethodSecurityExpressionHandler 扩展了它，所以之前的所有功能都保持不变。在我的配置中，我同时使用了 GlobalMethodSecurityConfiguration 和 WebSecurityConfigurerAdapter。

@Configuration
@EnableGlobalMethodSecurity
public class MethodSecurityConfiguration extends GlobalMethodSecurityConfiguration {

  @Override
  protected MethodSecurityExpressionHandler createExpressionHandler() {
    return new OAuth2MethodSecurityExpressionHandler();
  }
}

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
  ...
}


@Configuration
@Import({ SecurityConfiguration.class, MethodSecurityConfiguration.class })
public class AppConfiguration {
  ...
}
