java.lang.IllegalStateException（未找到方法）：使用自定义过滤器在一次测试中多次调用 MockMvc.perform

Question

为了在带有 @AuthenticationPrincipal 注释的 spring 安全保护 REST api 中检索 UserDetails 对象，我在 MockMvc 对象中添加了一个自定义过滤器，一些东西喜欢：

@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，我尝试在某些测试中调用 mockMvc 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()))
    }
}

当运行测试时，java.IllegalStateException 抛出第二个 perform 赞：

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

如果测试中只有一个 perform 调用，则一切正常。

请问有谁能帮忙解决一下吗

我遇到了同样的问题，我通过在我的 MockSpringSecurityFilter 中添加以下方法解决了这个问题

public void getFilters(MockHttpServletRequest mockHttpServletRequest){}
