Spring data MongoDb配置

Question

看起来我无法使这个mongoTemplate bean在我的项目中正常工作:( 这是我的mongo配置的xml:

<?xml version="1.0" encoding="UTF-8"?>
   <beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:mail="http://www.springframework.org/schema/integration/mail"
xmlns:int="http://www.springframework.org/schema/integration"
xmlns:util="http://www.springframework.org/schema/util"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

        http://www.springframework.org/schema/data/mongo
      http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd">

<mongo:mongo host="localhost" port="27017" />
<mongo:db-factory dbname="test" />

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

</beans>

我在项目中添加了以下文件： mongo-java-driver 2.11.0.jar，spring-data-commons-1.5.1.RELEASE.jar，spring-data-mongodb-1.2.1.RELEASE.jar

当然，我也在本地服务器上安装了mongodb。 以下是我遇到的异常：

有什么想法吗？谢谢...

我在我的项目中也有org.springframework.core-3.0.5.RELEASE.jar。 - Urbanleg

Answer 1

我正在使用spring-core3.0.5，当我将其更改为3.0.7时，它可以工作！

有人知道mongoDB spring数据支持的最低要求是spring-core必须是3.0.7吗？

- Urbanleg

显然不是这样的：请参见Spring Data MongoDB文档中的要求。 - Trevor Gowing

我非常确定这是一个错误。 - Urbanleg

Answer 2

我猜测您可能存在身份验证问题，请在配置db-factory时指定mongodb的凭据。

以下是我的配置，以便澄清：

<mongo:mongo host="127.0.0.1" port="27017" />
<mongo:db-factory id="mongoDbFactory" dbname="${db.name}" username="${db.username}" password="${db.password}"/>

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

我认为你的Spring配置还有其他问题，我不认为你的MongoDB配置是问题所在。不幸的是，我不是Spring专家，所以我不确定具体是什么问题，非常抱歉无法提供更多帮助。 - Trevor Gowing

请查看以下关于“Context initialization failed”错误的编程问题：http://stackoverflow.com/questions/4342492/spring-framework-error-context-initialization-failed - http://stackoverflow.com/questions/11382718/context-initialization-failed-or-loading-properties - 它们可能会有所帮助。 - Trevor Gowing

Answer 3

http://jira.grails.org/browse/GPMONGODB-178?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel

他们说这个问题无法解决，因为Spring升级已经解决了它。

Answer 4

在您的mongoTemplate中，您引用了mongoDBFactory，但是您没有为工厂指定id属性。

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

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

Answer 5

这是一个Java配置：

@Configuration
public class Config(){
@Bean
public MongoDbFactory mongoDbFactory() throws UnknownHostException{
return new SimpleMongoDbFactory(new MongoClient(new MongoClientURI(protocol://username:password@servername/databasename)),"Database_name_here"); //mongodb is the protocol
}    

@Bean
public MongoTemplate mongoTemplate() throws UnknownHostException{
return new MongoTemplate(mongoDbFactory);
}
}

如果你想在主类中引导这个配置，你可以像这样使用 Spring 的 AnnotationConfigApplicationContext：

ApplicationContext context = new AnnotationConfigApplicationContext(Config.class);
MongoOperations template = context.getBean(MongoTemplate.class);

然后，您将在MongoOperations的实例上调用所有MongoTemplate的方法。
