Question

我是Jhipster的新手。我用mongodb创建了网关项目。我在docker中启动了jhipster-registry和mongodb。没有其他微服务。当我调试网关项目时，我发现下面的错误：

我在DatabaseConfiguration.java类的getDatabaseName（）方法中设置了一个断点，并调试了getwayApp.java。我发现除了值为'mongodb：// localhost / test'的url之外，mongoProperties的所有属性都是null。我在application-dev.yml中配置了数据，如下所示：

data:
    cassandra:
        contactPoints: localhost
        protocolVersion: V4
        compression: LZ4
        keyspaceName: gateway
        repositories:
            enabled: false
        mongodb:
         host: localhost
         port: 27017
         uri: mongodb://localhost:27017
         database: jhipsterMongodbSampleApplication

但是我没有配置它的结果相同。

我应该如何以及在何处在网关中配置mongodb？提前谢谢。

Answer 1

您将mongodb块放在cassandra下，减少缩进。

另外，请不要忘记应在注册表中为应用程序定义应用程序属性，如部署。

mongoProperties属性为null
