如何在Spring Boot中测试CORS？当我尝试使用MockMvcBuilders时，尽管起源错误，它始终返回200

下面的测试（我包括两个类来查看是否可以工作）都没有调用控制器的问题。我希望它拒绝CORS问题，因为我没有添加任何CORS配置。（然后我想用CORS配置进行测试并通过）。如何在Spring Boot中测试CORS？当我尝试使用MockMvcBuilders时，尽管起源错误，它始终返回200

我该如何强制CORS失败？

第一次尝试：

       //CORS HEADERS 
       .header("Access-Control-Request-Method", "DELETE")

     ); 

     actions.andExpect(status().isOk()) 
      .andExpect(content().contentType(MediaType.APPLICATION_JSON_UTF8)); 

     TestDateResponse response = objectMapper.readValue(actions.andReturn().getResponse().getContentAsString(), TestDateResponse.class);

CORS不喜欢的工作。

要检查CORS，必须对URL执行预检操作。这不是一个POST，而是一个OPTIONS请求，针对与CORS头部完全相同的URL。

通过该调用，如果允许或不允许真正的调用（禁止DELETE），您将收到CORS响应。

类似的东西应该工作：

ResultActions actions = mockMvc.perform(
     options("/v1/testdate")  
      .contentType(MediaType.APPLICATION_JSON) 
      //CORS HEADERS 
      .header("Access-Control-Request-Method", "DELETE") 
      .header("Origin", "https://evil.com") 
    );

，然后简单地断言的预期响应头。

我得到这个错误：'javax.servlet.ServletException：处理程序没有适配器[org.springframew[email protected]82c57b3]：DispatcherServlet配置需要包含一个HandlerAdapter来支持这个处理程序' –

您是否在您的RequestController或您的RequestMapping上配置了交叉原点？例如与：@CrossOrigin（origins =“http://not-evil.com”） –

不，我不知道。我需要吗？这会解决这个错误吗？有没有办法让自定义的适配器bean摆脱这个错误？ –
