升级 spring 3.1 时遇到有关 HttpStatusCode 的问题

Question

伙计们 当我将 spring 2.65 升级到 3.1.0 时，我遇到了一个奇怪的问题。 这是代码：

import org.springframework.http.HttpStatus
import org.springframework.http.HttpStatus.OK
import org.springframework.http.HttpStatusCode
import org.springframework.web.server.ServerWebExchange


    @Test
    fun `and the operation is successful it should create and emit the audit event`() {
        private val mockExchange = mockk<ServerWebExchange>()
        every { mockExchange.authorizationData() } returns null
        every { mockExchange.response.statusCode } returns HttpStatus.OK

        mockSuccessfulFilterOperations()

        assertDoesNotThrow {
            auditLoggerFilter.filter(mockExchange, mockChain).block()
        }

        verify(exactly = 1) { auditLoggerService.publishAuditEvent(any(), SUCCESS) }
        confirmVerified(auditLoggerService)
    }

异常（每个 {mockExchange.response.statusCode } 返回 HttpStatus.OK）：

org.springframework.http.HttpStatusCode
java.lang.InstantiationError: org.springframework.http.HttpStatusCode

但是我读了doc，HttpStatus并没有被弃用，为什么它有异常？

我尝试使用：

every { mockExchange.response.statusCode } returns HttpStatusCode.valueOf(200)

还是不行。

Answer 1

问题是某些方法使用

HttpStatusCode

参数。我假设这样的方法在

auditLoggerService

中并且它是

publishAuditEvent()

。如果这个参数类型是

HttpStatusCode

，那么需要改为

HttpStatus

。因此，会出现错误，但这并没有什么问题，只需通过

HttpStatus

运算符将此参数转换为

as

类型即可。

测试哪里有这样的异常：

@Test
fun `log http response`(): Unit = runBlocking {
    val loggingService = mockk<IntegrationLoggingService> {
        every { logHttpResponse(any(), any()) } returns mockk()
    }
    val responseDecorator = HttpResponseLoggingDecorator(
        loggingService,
        MockServerHttpResponse().apply { statusCode = HttpStatus.BAD_GATEWAY }
    )

    responseDecorator.writeWith(messageBodyFlux()).awaitSingleOrNull()

    coVerify(exactly = 2) { loggingService.logHttpResponse(any(), any()) }
}

将

HttpStatusCode

参数转换为

HttpStatus

类型的方法：

loggingService.logHttpResponse(body = null, statusCode as HttpStatus)
