Cloudfoundry Spring MongoDB 示例应用程序部署失败答案

【问题标题】：Cloudfoundry Spring MongoDB sample application fails to deployCloudfoundry Spring MongoDB 示例应用程序部署失败
【发布时间】：2012-08-27 21:44:33
【问题描述】：

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。我在自己的所有应用程序中也遇到了这个错误，从命令行和 STS 3.0.0 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 1 类 org.cloudfoundry.runtime.env.MongoServiceInfo 类型的服务，但发现0

【解决方案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”。

【解决方案2】：

您是否更改了预期的 mongo db 的名称？ hello-spring-mondgodb 应用程序是 configured 以查找名为“hello”的数据库（SimpleMongoDbFactory 的第二个构造函数 arg）。也许尝试更新此属性以反映您的 mongo db 的名称并重新推送。

希望对你有帮助

【解决方案3】：

hello-spring-mongodb 无需更改配置即可运行。它在我的 CF 安装上成功部署。首先，我创建了一个 mongoDB 服务：

vmc create-service mongoDB

然后我从目标目录运行：vmc push hello-sping-mongodb

C:\eclipseWork\Indigo\hello-spring-mongodb\target>vmc push hello-spring-mongodb

可以尝试先创建mongoDB服务再推送应用吗？

【讨论】：

这令人费解。我首先尝试创建 MongoDB 服务，尝试为它命名各种东西，尝试了我能想到的一切。我在 OSX 上。有效的一件事是删除 Spring 配置文件的使用并让 Cloud Foundry 自动重新配置我用于本地测试的 MongoDbFactory bean。
我没有改行——只是直接从上面链接的 github repo 中克隆出来的。

【解决方案4】：

您的 root-context.xml 中似乎没有定义云配置文件配置。再次检查您是否具有以下配置：

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg ref="mongoDbFactory"/>     
</bean>


<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>

【讨论】：

非常感谢您参与其中，但同样，我是直接从 repo 克隆的——这正是我的 root-context.xml 的样子。似乎我可能不是唯一遇到此错误的人：stackoverflow.com/questions/12132688/…
重现此错误的唯一方法是将云配置文件放入 cmets。

【解决方案5】：

确保服务名称匹配，并更新 cloudfoundry-runtime 版本。请参阅我对另一个问题的回答，但有相同的例外 here。
