方法级别的＃oauth2安全表达式

我应该怎么做才能在方法级别上使用＃oauth2安全表达式，例如下面的示例？

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

如果我请求该资源，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ResourceServerConfiguration中指定访问权限，而不是@Controllers的方法，则同样的方法会很好地工作

@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”）之类的标准安全表达式可以按预期工作。因此，可能我必须告诉我的AspectJMethodSecurityInterceptor如何使用OAuth2WebSecurityExpressionHandler。有任何想法吗？

回答：

要启用＃oAuth2安全表达式，只需要将默认表达式处理程序设置为OAuth2MethodSecurityExpressionHandler而不是DefaultMethodSecurityExpressionHandler。由于OAuth2MethodSecurityExpressionHandler仍然对其进行了扩展，因此整个先前的功能保持不变。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 {
  ...
}
