下面是我为支持连接而添加的配置。但我只在应用程序启动时遇到异常。我能够连接简单的 MongoDB，但使用 Cosmos API 我得到了

复合索引目前不支持嵌套文档或数组。

@Autowired
    private JaversMongoProperties javersMongoProperties;
    @Autowired
    private MongoDbFactory mongoDbFactory; //from spring-boot-starter-data-mongodb
    @Autowired
    @Qualifier("javersMongoClientOptions")
    private Optional<MongoClientOptions> mongoClientOptions;

    @Bean(name = "JaversFromStarter")
    @ConditionalOnMissingBean
    public Javers javers() {
        logger.info("Starting javers-spring-boot-starter-mongo ...");

        MongoDatabase mongoDatabase = initJaversMongoDatabase();

        MongoRepository javersRepository = createMongoRepository(mongoDatabase);

        return JaversBuilder.javers()
                .registerJaversRepository(javersRepository)
                .withProperties(javersMongoProperties)
                .withObjectAccessHook(javersMongoProperties.createObjectAccessHookInstance())
                .build();
    }

    private MongoDatabase initJaversMongoDatabase() {
        if (!javersMongoProperties.isDedicatedMongodbConfigurationEnabled()) {
            MongoDatabase mongoDatabase = mongoDbFactory.getDb();
            logger.info("connecting Javers to Mongo database '{}' configured in spring.data.mongodb properties",
                        mongoDatabase.getName());
            return mongoDatabase;
        } else {
            MongoDatabase mongoDatabase = JaversDedicatedMongoFactory.createMongoDatabase(javersMongoProperties, mongoClientOptions);
            logger.info("connecting Javers to Mongo database '{}' configured in javers.mongodb properties",
                        mongoDatabase.getName());
            return mongoDatabase;
        }
    }

您使用错误的方法创建MongoRepository。你应该使用这个：

    /**
     * MongoRepository compatible with Amazon DocumentDB.
     * <br/>
     *
     * Compound index on <code>commitProperties</code> isn't created.
     * <br/><br/>
     *
     * See <a href="http://docs.aws.amazon.com/documentdb/latest/developerguide/functional-differences.html">functional differences</a>.
     */
    public static MongoRepository mongoRepositoryWithDocumentDBCompatibility(MongoDatabase mongo, int cacheSize) {
        return new MongoRepository(mongo, cacheSize, DOCUMENT_DB);
    }
