請求Url和視圖名相同時mockmvc測試

Question

測試控制器：

@Controller
@RequestMapping("/test")
public class TestController {

      @RequestMapping(method = GET)
      public void test(Model model) {
      }

}

聯合測試：

import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.*;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.*;

import org.junit.Test;
import org.springframework.test.web.servlet.MockMvc;
public class Test2 {

  @Test
  public void testPage() throws Exception {
    TestController controller = new TestController();
    MockMvc mockMvc = standaloneSetup(controller).build();//.setSingleView(new InternalResourceView("/WEB-INF/views/test.jsp"))
    mockMvc.perform(get("/test"))
           .andExpect(view().name("test"));
  }

}

運行JunitTest，出現異常：

javax.servlet.ServletException: Circular view path [test]: would dispatch back to the current handler URL [/test] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

我知道我可以使用 setSingleView，但我檢查了 StandaloneMockMvcBuilder 的 api

public StandaloneMockMvcBuilder setViewResolvers(ViewResolver... resolvers)
Set up view resolution with the given ViewResolvers. If not set, an InternalResourceViewResolver is used by default.

這意味着使用了 InternalResourceViewResolver，所以 servlet 將調度到“test.jsp”而不是“/test”，它不應該是一個圓圈，並且當我在瀏覽器中測試時它運行良好。或者 StandaloneMockMvcBuilder 不使用任何視圖解析器？

我使用的是 Spring MVC，而不是 Springboot，我遵循了這個並成功設置。
