如何在Spring boot集成测试中捕获ApplicatonEvent？

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
importimport org.springframework.context.ApplicationEvent;
import org.springframework.context.ApplicationEventPublisher;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;
import org.springframework.test.web.servlet.result.MockMvcResultMatchers;

@SpringBootTest
@AutoConfigureMockMvc
public class MyIntegrationTest {

    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private ApplicationEventPublisher eventPublisher;

    @Test
    public void testPublishEvent() throws Exception {
        // 发布事件
        eventPublisher.publishEvent(new MyCustomEvent("Hello, World!"));

        // 执行HTTP请求并验证事件是否被捕获
        mockMvc.perform(MockMvcRequestBuilders.get("/api/my-endpoint"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.content().string("Event captured"));
    }

    // 自定义事件类
    private static class MyCustomEvent extends ApplicationEvent {
        private final String message;

        public MyCustomEvent(String message) {
            super(message);
            this.message = message;
        }

        public String getMessage() {
            return message;
        }
    }
}
