如何在Java Spring中模拟RestTemplate？

import org.springframework.boot.test.autoconfigure.web.client.RestClientTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.web.client.MockRestServiceServer;
import import org.springframework.web.client.RestTemplate;

@RestClientTest
public class MyRestTemplateTest {
    // ...
}

@Autowired
private RestTemplate restTemplate;

private MockRestServiceServer mockServer;

@Test
public void testRestTemplate() {
    // 模拟请求和响应
    mockServer.expect(requestTo("/api/endpoint"))
            .andExpect(method(HttpMethod.GET))
            .andRespond(withSuccess("Hello, World!", MediaType.TEXT_PLAIN));

    // 发送请求
    String result = restTemplate.getForObject("/api/endpoint", String.class);

    // 验证结果
    assertEquals("Hello, World!", result);

    // 验证请求是否符合预期
    mockServer.verify();
}
