如何在不使用Spring Boot的情况下注入假客户端并调用REST端点

    <groupId>org.mockito</groupId>

public interface MyRestClient {
    String getData();
}

import org.junit.Test;
import org.mockito.Mock;
import org.mockito.Mockito;

public class MyRestClientTest {

    @Mock
    private MyRestClient myRestClient;

    @Test
    public void testGetData() {
        // 设置假的REST端点响应
        Mockito.when(myRestClient.getData()).thenReturn("Mocked data");

        // 调用假客户端的getData()方法
        String data = myRestClient.getData();

        // 断言假的响应数据
        Assert.assertEquals("Mocked data", data);
    }
}
