Spring Boot 反应式和 mongodb '命令插入需要身份验证'

Question

我在 docker 容器中使用 Spring Boot 2.3.1 和 webflux 和 MongoDB 创建了一个项目。项目正常启动并使用 application.properties 中声明的参数在 MongoDB 中连接。

当我尝试执行 CRUD 操作“插入”时，问题就开始了。生成以下日志：

500 Server Error for HTTP POST "/configuracao"

阅读Spring Data MongoDB Reference Documentation，我按照建议为 mongodb 配置创建了一个自定义 Bean：

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

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

我尝试了 MongoClient 和 ReactiveMongoDatabaseFactory，但我无法执行 save 方法。总是返回'命令插入需要身份验证'。

对于 docker 容器，我使用此脚本在容器启动后初始化数据库：

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

应用程序在启动时连接成功，我可以使用 mongo-express 或其他 gui 工具连接数据库。

我在这里做错了什么？如何配置此 Spring Boot 反应式应用程序以与 mongodb 正确集成？

提前致谢。

如果您仍然遇到此问题。我有一个类似的问题，并通过使用 reactiveMongoClient() 而不是 mongoClient() 来解决它。

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");
}

你的 bean 应该看起来像：

@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");
    }
}
