如何在Spring boot集成测试中模拟rest客户端

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

@SpringBootTest
@AutoConfigureMockMvc
public class MyIntegrationTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    public void testRestClient() throws Exception {
        // 模拟发送GET请求
        mockMvc.perform(MockMvcRequestBuilders.get("/api/endpoint"))
                .andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.content().string("Hello, World!"));
    }
}
