我在rest中编写函数来自动生成具有admin角色的用户。
UserController.java

@RestController
@RequestMapping("users")
public class UserController {

    @Autowired
    private UserRepository userRepo;
    @Autowired
    private TokenRepository tokenRepo;
    
    @GetMapping("admin")
    public String getAdmin () {
        JSONObject report = new JSONObject();
        String dataAdmin = userRepo.findByUsername("admin");
        if(dataAdmin == null) {
            User myadmin = new User();
            myadmin.setUsername("admin");
            myadmin.setFirstname("admin");
            myadmin.setLastname("admin");
            myadmin.setEmail("admin@admin");
            myadmin.setRole("admin");
            userRepo.save(myadmin);
            report.put("message", "admin generated");
        } else {
            report.put("message", "admin only generated once");
        }
        return report.toString();
    }

我试图按照这里的指示https://www.springboottutorial.com/unit-testing-for-spring-boot-rest-services。在 * 单元测试Http获取操作 * 部分。我得到了几个问题，也尝试不同的解决方案，直到我遇到这个Unit testing a Get request in a spring project从stackoverflow。下面是测试脚本，我已经到目前为止。

package blablaaa.order;

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

import org.json.JSONObject;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.http.MediaType;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.MvcResult;
import org.springframework.test.web.servlet.RequestBuilder;
import org.springframework.test.web.servlet.request.MockMvcRequestBuilders;

import blablaaa.order.controller.UserController;
import blablaaa.order.dao.UserRepository;
import blablaaa.order.model.User;

//@ExtendWith(SpringExtension.class)
//@SpringBootTest
@WebMvcTest(value = UserController.class)
class OrderApplicationTests {
//  
    @Autowired
    private MockMvc mockMvc;
    
    @MockBean
    private UserRepository userRepo;

    @Test
    void contextLoads() throws Exception{

        User myadmin = new User();
        myadmin.setUsername("admin");
        myadmin.setFirstname("admin");
        myadmin.setLastname("admin");
        myadmin.setEmail("admin@admin");
        myadmin.setRole("admin");
        
        List<User> myUser = new ArrayList<>();
        myUser.add(myadmin);
        RequestBuilder rb = MockMvcRequestBuilders.get("/users/admin").accept(MediaType.APPLICATION_JSON);
        MvcResult result = mockMvc.perform(rb).andReturn();
        JSONObject expect = new JSONObject();
        expect.put("message", "admin generated");
//      System.out.println(result.toString());
        System.out.println(expect.toString());
//      Assertions.assertTrue(result.toString().contains(expect.toString()));
    }

}

我不知道，测试应该如何编写。任何关键字有关这一点？
[更新]
下面是我的主要：

// OrderApplication.java
@SpringBootApplication
@EnableMongoRepositories("blablaaa.order.dao")
public class OrderApplication {

    public static void main(String[] args) {
        SpringApplication.run(OrderApplication.class, args);
    }

}

这是我的程序错误日志

Description:

Field tokenRepo in blablaaa.order.controller.UserController required a bean named 'mongoTemplate' that could not be found.

The injection point has the following annotations:
    - @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean named 'mongoTemplate' in your configuration.
