spring - Cloudfoundry Spring MongoDB 示例应用程序部署失败

Question

当我尝试使用 MongoDB ( hello-spring-mongodb ) 部署示例 Java Spring 应用程序时，我收到下面粘贴的错误，这表明 MongoDB 服务无法绑定(bind)。我也在我自己的所有应用程序中遇到此错误，从命令行和 STS 3.0.0 进行部署。关键错误是:

创建名为“mongoDbFactory”的 bean 时出错:调用 init 方法失败；嵌套异常是 org.cloudfoundry.runtime.env.CloudServiceException:预期有 1 个类 org.cloudfoundry.runtime.env.MongoServiceInfo 类型的服务，但发现有 0 个

Answer 1

替换:

<beans profile="default">
    <mongo:db-factory id="mongoDbFactory" dbname="pwdtest" host="127.0.0.1" port="27017"    username="mongo_user" password="passwd"/>
</beans>

<beans profile="cloud">
    <cloud:mongo-db-factory id="mongoDbFactory"/>
</beans>

与:

<mongo:db-factory
    id="mongoDbFactory"
    dbname="${mongo.name}"
    host="${mongo.host}"
    port="27017"
    username="${mongo.username}"
    password="${mongo.password}" />

...并且 cloudfoundry 自动重新配置将正确完成它的工作。如果仍有问题，请在 Spring Explorer View > Properties 中右键单击您的项目，然后启用“Beans Validator”。
