经过几个小时的努力，我终于找到了解决办法。它可能对某人有帮助。我把密码贴在这里。

@DataMongoTest(excludeAutoConfiguration = {SecurityAutoConfiguration.class,
        RedisAutoConfiguration.class, MongoDBTxnConfiguration.class,
        RedisRepositoriesAutoConfiguration.class, 
        SecurityFilterAutoConfiguration.class, 
        SecurityAutoConfiguration.class})
@Profile("test")
@ActiveProfiles("test")
@ComponentScan(basePackages = {"com.app.rain"}, excludeFilters={
          @ComponentScan.Filter(type=FilterType.ASSIGNABLE_TYPE, 
                  value= {MongoDBTxnConfiguration.class,SecurityCloudConfig.class})})
@Import(TestMongoDBConfig.class)
public class Test0 {
    @Autowired
    private ValidationCategoryController controller;
    @Autowired
    @Qualifier("validations")
    private ValidationService vldnService;
    @Test
    void testAllValidationsBeforeEntry() {
        System.out.println("controller : " + controller);
        assertEquals(true, true);
    }
}

班级 TestMongoDBConfig 课堂看起来像这样。

@Profile("test")
@ActiveProfiles("test")
@Configuration
public class TestMongoDBConfig implements InitializingBean, DisposableBean {
    private MongodExecutable executable;
    @Override
    public void afterPropertiesSet() throws Exception {
        IFeatureAwareVersion version = de.flapdoodle.embed.mongo.distribution.Versions
                .withFeatures(new GenericVersion("4.0.0"), Version.Main.PRODUCTION.getFeatures());
        IMongoCmdOptions cmdOptions = new MongoCmdOptionsBuilder().useNoPrealloc(false).useSmallFiles(false)
                .master(false).verbose(false).useNoJournal(false).syncDelay(0).build();
        int port = Network.getFreeServerPort();
        IMongodConfig mongodConfig = new MongodConfigBuilder().version(version)
                .net(new Net(port, Network.localhostIsIPv6())).replication(new Storage(null, "testRepSet", 5000))
//            .configServer(true)
                .configServer(false).cmdOptions(cmdOptions).build();
        MongodStarter starter = MongodStarter.getDefaultInstance();
        executable = starter.prepare(mongodConfig);
        executable.start();
    }
    @Primary
    @Bean(name = "test1")
    public MongoClient mongoClient() {
        MongoClient mongoClient = MongoClients.create();
        return mongoClient;
    }
    @Override
    public void destroy() throws Exception {
        executable.stop();
    }
}
