我想要使用Spring-Data和MongoDB来运行一个简单的“Hello World”程序。Spring似乎忽略了在<mongo:mongo/>
元素中配置的MongoDB主机IP地址,而是尝试连接到127.0.0.1
。
根据各种教程,这是我的Spring配置XML:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.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-3.0.xsd">
<mongo:mongo host="10.125.0.68" 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>
该程序:
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.GenericXmlApplicationContext;
import org.springframework.data.mongodb.core.MongoOperations;
public class Test1
{
public static void main(String[] args)
{
ApplicationContext ctx = new GenericXmlApplicationContext("SpringConfig.xml");
MongoOperations mo = (MongoOperations)ctx.getBean("mongoTemplate");
DbDocument a = new DbDocument("John Smith", "jsmith@plymouth.org");
if (!mo.collectionExists(DbDocument.class)) //<<<----- Exception here
mo.createCollection(DbDocument.class);
mo.save(a);
}
}
抛出的异常:

我能够使用GUI工具连接到指定地址10.125.0.68
的Mongo实例,并确认存在一个名为test
的数据库。
我在StackOverflow上找到了一些相关问题,但没有一个足够类似于我的情况以解决这个问题。
