Spring启动项目测试失败Mockito无法模拟此类或接口UserRepository

我正在做一个SpringBoot项目，它的控制器、服务和存储库都工作得很好。我用邮递员测试了一下

我是mockito的新手，正在尝试测试我的项目。 我有以下测试课程：

package com.spr;

import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;

import java.util.ArrayList;
import java.util.List;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.junit4.SpringRunner;

import com.spr.entity.User;
import com.spr.repository.UserRepository;
import com.spr.service.UserService;

@RunWith(SpringRunner.class)
@SpringBootTest
public class UserRepositoryTest {

@Autowired
private UserService userService;

@MockBean
private UserRepository userRepository;

@Before
public void init() {
}

@Test
public void getAllUsersTest() {
    List<User> users = new ArrayList<User>();

    users.add(new User("User1", "user1@email.com", "male"));
    users.add(new User("User2", "user2@email.com", "female"));

    when(userRepository.findAll()).thenReturn(users);

    List<User> userList = userService.getUsers();

    assertEquals(2, userList.size());
    verify(userRepository, times(1)).findAll();
}
}

我做错了什么

编辑：

这是我的pom.xml和UserRepository

我在类路径中有mockito-core-2.23.4.jar，问题是Java版本。

---

我使用的是java版本“1.8.0\u 05”，我将它升级到java版本“1.8.0\u 221”，它运行正常。

你的mockito版本是什么？还有spring boot？请添加

UserRepository

。您是否尝试添加新的

Mockito

版本？是的，我尝试了，但错误相同：（我也尝试了其他版本。）
