Spring 引导测试失败，没有“org.springframework.boot.autoconfigure.web.servlet.DispatcherServletPath”类型的限定 bean

Question

我有一个运行时可以运行的 Spring Boot 应用程序，但是当我尝试使用 MockMVC 进行一些测试时出现错误。错误是由SecurityConfig中的一行触发的：

val publicUrls = arrayOf(
    "/telemetry/**",
    "/login",
    "/logout"
)

override fun configure(http: HttpSecurity) {
    http
        .csrf().ignoringAntMatchers(*publicUrls)
        .and()
        .authorizeRequests()
        .requestMatchers(EndpointRequest.to("status", "info")).permitAll()

        // The following line is the problem
        .requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()   // <-- causes error

        .antMatchers(*publicUrls).permitAll()
        .antMatchers("/system/**").hasRole("SUPER")
        .antMatchers("/admin/**").hasRole("ADMIN")
        .anyRequest().authenticated()
    //.and()
    //.oauth2Login();
}

如果没有允许访问静态资源的行，则测试可以正常工作。有了这条线，我得到了下面的错误（带有堆栈跟踪）。如果我添加一个实现DispatcherServletPath 的类，并用@Component 注释，那么我会得到一个错误expected single matching bean but found 2:。

测试代码为：

@SpringBootTest
@AutoConfigureMockMvc
@WebAppConfiguration
@ComponentScan("com.controlj.monitor.service")
@RunWith(SpringJUnit4ClassRunner::class)
class SampleTest {

    @MockBean
    private lateinit var mockTelemetryService: TelemetryService
    @Autowired
    private lateinit var springSecurityFilterChain: FilterChainProxy

    private lateinit var mvc: MockMvc

    @Before
    fun setup() {
        mvc = MockMvcBuilders.standaloneSetup(TelemetryEndpoint(mockTelemetryService))
            .apply<StandaloneMockMvcBuilder>(SecurityMockMvcConfigurers.springSecurity(springSecurityFilterChain))
            .build()
    }

   @Test
    fun testTelemetryApi() {
        val postMapping = TelemetryEndpoint::post.findAnnotation<PostMapping>()?.value?.first()
        mvc.perform(post(postMapping, "badKey", 123456)
            .contentType(MediaType.APPLICATION_JSON))
            .andExpect(status().`is`(404))
   }
}

我该如何解决这个问题？

Answer 1

尝试为您自己的 DispatcherServletPath 实现命名

@Component("dispatcherServlet")
public class Your_Dispatch_Servlet implements DispatcherServletPath {
}

Answer 2

多年来，我一直在为此烦恼。对我来说，一些测试通过或失败取决于我如何运行它们，或者我是一起运行还是单独运行它们——这显然并不理想。但似乎我的安全配置中的同一行导致了我的问题。

我确定这不是最终解决方案，但作为一种解决方法，我现在已经更换了

PathRequest.toStaticResources().atCommonLocations()

与

new AntPathRequestMatcher("/webjars/**", "GET")

我只使用来自WebJars 的静态资源，所以这足以让我暂时克服这个问题。不过，我想问题实际上出在其他地方。我很想知道到底发生了什么。
