Question

我下载了STS 3.0.0并且一直试图使用Roo将简单的弹簧应用程序放到CloudFoundry上。

第1步：这是我的roo脚本

// Spring Roo 1.2.2.RELEASE [rev 7d75659] log opened at 2012-08-26 22:36:52
project --topLevelPackage com.nroots.tracker
mongo setup --cloudFoundry true
entity mongo --class ~.domain.Trackable --testAutomatically 
field string --fieldName name --notNull --sizeMin 3 
field date --fieldName datetime --type java.util.Date --dateTimeFormatPattern yyyyMMddHHmmssSSS 
repository mongo --interface ~.repository.TrackableRepository --entity ~.domain.Trackable 
service --interface ~.service.TrackableService --entity ~.domain.Trackable 
web mvc setup 
web mvc all --package ~.web 
logging setup --level DEBUG --package ROOT
logging setup --level DEBUG --package PROJECT 
perform eclipse

第2步：将项目导入STS 我得到一个对话框询问我是否要转换旧的STS项目，我选择是。项目将被导入并成功构建。

第3步：在roo shell仍然运行的情况下，我修改了Trackable域类并添加了一个double []数组来保存gps坐标。然后在Package Explorer视图中，我做了一个Refactor＆gt;推入该项目再次成功建立。

第4步：部署到CloudFoundry 使用STS CloudFoundry扩展，我创建了一个新的VMware CloudFoundry服务器并添加我的应用程序并将其绑定到MongoDB服务......

但是，我在部署期间在控制台视图中收到这些例外：

Stopping Tomcat because the context stopped.

Answer 1

将applicationContext-mongo.xml更改为如下所示：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<beans xmlns="http://www.springframework.org/schema/beans"  xmlns:cloud="http://schema.cloudfoundry.org/spring" xmlns:context="http://www.springframework.org/schema/context" xmlns:mongo="http://www.springframework.org/schema/data/mongo" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd        http://www.springframework.org/schema/data/mongo        http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd        http://schema.cloudfoundry.org/spring http://schema.cloudfoundry.org/spring/cloudfoundry-spring-0.8.xsd">

<mongo:repositories base-package="com.nroots.tracker"/>

<context:annotation-config/>

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

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

删除该行：

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

Answer 2

我首先添加了一个service-name属性来解决这个异常：

<cloud:mongo-db-factory id="mongoDbFactory" service-name="my-service-name"/>

其中“my-service-name”是我在STS中为MongoDB服务设置的名称。

然后我遇到一个关于MongoTemplate构造函数参数为null的异常，我通过将cloudfoundry-runtime版本从0.8.0更新到0.8.2来解决这个问题。

Answer 3

Spring似乎无法实例化绑定到您的CF mongo服务的mongoDbFactory。我假设您的配置类似于以下内容：

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

    <beans profile="default">
            <mongo:db-factory id="mongoDbFactory" dbname="DB name" host="127.0.0.1" port="27017" username="username" password="changeme"/>
    </beans>

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

您的应用程序是否在本地运行？
