spring - MockRestServiceServer 未正确验证请求

Question

我正在尝试为我的 spring 集成流程编写集成测试。我想用MockRestServiceServer 记录传出请求(使用 http:outbound-gateway)并将其匹配到 Rest 服务器。但是，当我调用 mockServer 的验证方法时，它没有按预期进行验证。

我正在按以下方式编写我的测试:

RestTemplate restTemplate = new RestTemplate();
MockRestServiceServer mockServer = MockRestServiceServer.createServer(restTemplate);

mockServer.expect(requestTo("adfasfadf.com")).andExpect(method(HttpMethod.GET));

// Call spring integration flow here

mockServer.verify();

当我检查 MockRestServiceServer 的验证方法时，它没有调用 RequestMatchers 的匹配方法，我认为这个逻辑有问题。我在这里遗漏了什么吗？

/**
 * Verify that all expected requests set up via
 * {@link #expect(RequestMatcher)} were indeed performed.
 * @throws AssertionError when some expectations were not met
 */
public void verify() {
    if (this.expectedRequests.isEmpty() || this.expectedRequests.equals(this.actualRequests)) {
        return;
    }
    throw new AssertionError(getVerifyMessage());
}

经过几个小时的调试，我意识到 MockRestServiceServer 在执行请求期间运行匹配器。所以，如果你有一个围绕请求执行的异常处理程序，你的断言永远不会被正确断言。此代码来自运行匹配器的 RequestMatcherClientHttpRequest。

@Override
public ClientHttpResponse executeInternal() throws IOException {
    if (this.requestMatchers.isEmpty()) {
        throw new AssertionError("No request expectations to execute");
    }
    if (this.responseCreator == null) {
        throw new AssertionError("No ResponseCreator was set up. Add it after request expectations, "
                + "e.g. MockRestServiceServer.expect(requestTo(\"/foo\")).andRespond(withSuccess())");
    }
    for (RequestMatcher requestMatcher : this.requestMatchers) {
        requestMatcher.match(this);
    }
    setResponse(this.responseCreator.createResponse(this));

    return super.executeInternal();
}

我认为这应该被视为一个错误，因为我认为断言必须在应用程序执行后执行。
