#oauth2方法级别的安全性表达式

问题描述

如何才能在方法级别使用#oauth2安全表达式，如下面的示例所示?

What should I do to be able to use #oauth2 security expressions on method level like on the example below?

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

    return "[email protected]";
  }

如果我请求该资源，我会收到

If I do a request to that resource I receive

    [INFO] java.lang.IllegalArgumentException: Failed to evaluate expression '#oauth2.hasScope('read')'

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

如果我在ResourceServerConfiguration中而不是@Controllers的方法中指定访问权限，则同样的事情会很好

The same thing works well if I specify the access in my ResourceServerConfiguration instead of @Controllers' methods

@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')");
  }
}

像@PreAuthorize("permitAll")或@PreAuthorize("denyAll")这样的标准安全表达式可以正常工作.因此，可能我必须以某种方式告诉我的AspectJMethodSecurityInterceptor使用OAuth2WebSecurityExpressionHandler.有任何想法吗?

Standard security expressions like @PreAuthorize("permitAll") or @PreAuthorize("denyAll") work as expected. So, probably I have to tell somehow to my AspectJMethodSecurityInterceptor to use OAuth2WebSecurityExpressionHandler. Any ideas?

推荐答案

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.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.

To enable #oAuth2 security expressions it is only needed to set default expression handler as OAuth2MethodSecurityExpressionHandler instead of DefaultMethodSecurityExpressionHandler. Because OAuth2MethodSecurityExpressionHandler extends it anyway then the whole previous functionality remains the same. I my configuration I use both GlobalMethodSecurityConfiguration and 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 {
  ...
}
