Question

我为spring框架提供了以下mongo db配置：

    <?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: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.xsd
          http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

<mongo:mongo host="127.0.0.1" port="27017" />

<mongo:db-factory id="mongoDbFactory" username="admin" password="abc" dbname="test123"
    mongo-ref="mongo" />
<!-- <mongo:db-factory dbname="test123" /> -->

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

然而，当我启动spring框架时，它似乎并没有连接到test123数据库。它正在连接到默认的测试数据库。有人有什么想法吗？

您可以将xml更改为以下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: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-3.1.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">

 <!-- Default bean name is 'mongo' -->
 <mongo:mongo host="localhost" port="27017" />

 <bean id="mongoTemplate"
 class="org.springframework.data.mongodb.core.MongoTemplate">
 <constructor-arg ref="mongo" />
 <constructor-arg name="databaseName" value="test123" />

 </bean>

 <!-- To translate any MongoExceptions thrown in @Repository annotated classes -->
 <context:annotation-config />

</beans>

Mongo DB配置在加载时不起作用
