如何在Wiremock集成测试中模拟SpringBoot的MessageChannel中的发送方法

import com.github.tomakehurst.wiremock.WireMockServer;
import com.github.tomakehurst.wiremock.client.WireMock;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.MediaType;
import org.springframework.web.client.RestTemplate;

import static com.github.tomakehurst.wiremock.client.WireMock.*;

public class WiremockIntegrationTest {

    private static WireMockServer wireMockServer;

    @BeforeClass
    public static void setup() {
        wireMockServer = new WireMockServer(8080);
        wireMockServer.start();
        WireMock.configureFor("localhost", 8080);
    }

    @Test
    public void testMessageChannelIntegration() {
        // Define the mock behavior
        stubFor(any(urlPathEqualTo("/message"))
                .withHeader(HttpHeaders.CONTENT_TYPE, equalTo(MediaType.APPLICATION_JSON_VALUE))
                .withRequestBody(containing("message content"))
                .willReturn(aResponse()
                        .withStatus(200)
                        .withHeader(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_JSON_VALUE)
                        .withBody("{\"status\": \"success\"}")));

        // Send a request to the mock server
        RestTemplate restTemplate = new RestTemplate();
        String url = "http://localhost:8080/message";
        String requestBody = "{\"message\": \"message content\"}";
        String response = restTemplate.postForObject(url, requestBody, String.class);

        // Verify the response
        assertThat(response).isEqualTo("{\"status\": \"success\"}");
    }
}
