Java Spring Boot 2@WebMvcTest和OAuth2#OAuth2.hasScope控制器导致IllegalArgumentException

这是一个spring boot 2.0.6应用程序，使用MVC控制器，使用@PreAuthorize和#oauth2.hasScope保护控制器端点。我使用@WebMvcTest编写了控制器测试。但是，当调用

#oauth2.hasScope

时，似乎正在发出请求，但没有给出要与之进行比较的值。我怎么了

                .alwaysDo(document("{method-name}", preprocessRequest(prettyPrint()), preprocessResponse(prettyPrint())))
                .apply(springSecurity())
                .build();

        this.objectMapper = new ObjectMapper();
    }


@Test
@WithMockUser(username = "testclient", authorities = "foo")
public void givenValidUser_whenGetOrderDetailsWebEC_thenGetOrder() throws Exception {
    getMockMvc().perform(get("/ok")
            .header("Authorization", authorizationHeader()))
            .andExpect(status().isOk())
            .andExpect(content().string("ok"));
}
}

控制器

@PreAuthorize("#oauth2.hasScope('foo')")
@RequestMapping(value = "/ok", method = RequestMethod.GET)
public String ok() {
    return "ok";
}

Spring安全调试输出

servletPath:
pathInfo:/ok
headers: 
Authorization: Bearer 57962883-e379-433b-b613-1f888471fb84

任何关于我在设置中缺少什么的帮助都会非常有用。似乎确实有什么地方出错了，好像它实际上是在尝试验证是否返回了401/403。也不例外。减去编译所需的更改，这在Spring Boot 1.5.9下工作

如果我将模拟mvc注释替换为@SpringBootTest，这会起作用，但是我不需要这些测试上的数据库，所以我希望将其设置为不需要加载

之所以发生这种情况，是因为Spring使用的是

DefaultMethodSecurityExpressionHandler

。 见此：

要解决此问题，请执行以下操作：

从

AuthorizationServerConfig

添加以下新配置类

@配置
@EnableGlobalMethodSecurity（Prespenabled=true，securedEnabled=true）
公共类方法SecurityConfiguration扩展了GlobalMethodSecurityConfiguration{
@凌驾
受保护的MethodSecurityExpressionHandler createExpressionHandler（）{
返回新的OAuth2MethodSecurityExpressionHandler（）；
}
}

---

对我来说很重要的一点是，我已经在另一个配置上安装了

@EnableGlobalMethodSecurity

，因此spring最初忽略了新的配置类

Hi Rig，您是否尝试解决此问题？我面临着同样的问题，但还没有找到任何有用的解决方案。我从来没有让它在Blangero工作过。一个解决方案是禁用安全性，但我想要我的控制器，但我想验证它们的安全性是否也正常工作。当我在1.5.x和2.0应用程序之间使用我的公共接口库进行虚假通信时，我或多或少地放弃了这一努力。我可能会在新的一年里再次解决这个问题，所以也许我会找到解决办法。
