@EnableTransactionManagement
@EnableReactiveMongoRepositories
public class MongoConfiguration extends AbstractReactiveMongoConfiguration {

    @Value("${spring.data.mongodb.database}")
    private String database;

    @Bean
    public MongoClient mongoClient() {
        return MongoClients.create("mongodb://exampleapp:example@localhost:27017/exampledb");
    }

//    @Bean

//        return new SimpleReactiveMongoDatabaseFactory(MongoClients.create("mongodb://exampleapp:example@localhost:27017/exampledb"), database);
//    }

    @Override
    protected String getDatabaseName() {
        return database;
    }

db.auth('mongoadmin', 'mongoadmin')
db = db.getSiblingDB('exampledb')
db.createUser(
    {
        user: "exampleapp",
        pwd: "example",
        roles: [
            {
                role: "readWrite",
                db: "exampledb"
            }
        ]
    }
)

我在这里做错了什么？我如何配置这个spring boot reactive应用程序来与MongoDB紧密集成？

提前谢了。

以防你仍然有这个问题。我也遇到过类似的问题，并通过使用reactiveMongoClient（）而不是mongoClient（）解决了它。

替换：

 @Bean
public MongoClient mongoClient() {
    return MongoClients.create("mongodb://exampleapp:example@localhost:27017/exampledb");
}

与：

@Override
public MongoClient reactiveMongoClient() {
    return MongoClients.create("mongodb://exampleapp:example@localhost:27017/exampledb");
}

@EnableReactiveMongoRepositories
@Slf4j
public class MongoDBCConfig extends 
AbstractReactiveMongoConfiguration {

@Override
protected String getDatabaseName() {
    return "dbname";
}

@Override
public MongoClient reactiveMongoClient() {
    return MongoClients.create("mongodb://username:password@localhost:27017/authSource=auth-source");
    }
}
