用于检索 UserDetails spring安全保护restapi中的 @AuthenticationPrincipal 注解中，我在 MockMvc 对象，比如：

@ExtendWith(SpringExtension::class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
class BaseSpringIntegrationTest {
    @Autowired
    private lateinit var context: WebApplicationContext

    lateinit var mockMvc: MockMvc

    val mockUser = UsernamePasswordAuthenticationToken(MyUserDetails("MOCK_USER"), "MOCK_PASSWORD",  listOf(SimpleGrantedAuthority("MOCKED_ROLE")))

    @PostConstruct
    fun init() {
        mockMvc = MockMvcBuilders
            .webAppContextSetup(context)
            .apply<DefaultMockMvcBuilder>(springSecurity(mockSpringSecurityFilter))
            .build()
    }

    private val mockSpringSecurityFilter = object: Filter {
        override fun doFilter(req: ServletRequest, res: ServletResponse, chain: FilterChain) {
            with ((req as HttpServletRequest).userPrincipal) {
                if (this != null)
                    SecurityContextHolder.getContext().authentication = this as Authentication
                }
            chain.doFilter(req, res)
        }

        override fun destroy() {
            SecurityContextHolder.clearContext()
        }
    }
}

然后，我试着打电话给 mockMvc 在某些测试中，对象两次，如下所示：

class DummyTests: BaseSpringIntegrationTest() {
    @Test
    fun dummyTest() {
        mockMvc.perform(MockMvcRequestBuilders.post("<MY_URL>").principal(mockUser))
            .andExpect(MockMvcResultMatchers.status().`is`(HttpStatus.OK.value()))

        mockMvc.perform(MockMvcRequestBuilders.post("<ANOTHER_URL>").principal(mockUser))
            .andExpect(MockMvcResultMatchers.status().`is`(HttpStatus.OK.value()))
    }
}

运行测试时 java.IllegalStateException 第二次被抛出 perform 喜欢：

Method not found: BaseSpringIntegrationTest$mockSpringSecurityFilter$1.getFilters(org.springframework.mock.web.MockHttpServletRequest)
java.lang.IllegalStateException: Method not found: BaseSpringIntegrationTest$mockSpringSecurityFilter$1.getFilters(org.springframework.mock.web.MockHttpServletRequest)

    at org.springframework.test.web.servlet.request.MockHttpServletRequestBuilder.postProcessRequest(MockHttpServletRequestBuilder.java:831)
    at org.springframework.test.web.servlet.MockMvc.perform(MockMvc.java:173)

如果只有一个 perform 打电话测试，一切正常。
有谁能帮忙处理这个问题吗。
