春季数据 MongoDB 错误

Question

我正在尝试将 MongoDB 与 Java 和 Spring 一起使用。尝试加载应用程序时出现以下错误：

    org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 32 in XML document from file [E:\adaptor-JPSS-SA-RE_ssamanta_20150904-025119\bin\..\cfg\spring\beans.xml] is invalid; nes

我的 beans.xml 文件有以下内容：

<beans xmlns="http://www.springframework.org/schema/beans"  
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"

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

<mongo:mongo host="localhost" port="27017"  id="mongo" />

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

我的类路径中有以下三个 jar：

mongo-java-driver-2.12.4.jar
spring-data-mongodb-1.5.2.RELEASE.jar
spring-data-commons-1.10.2.RELEASE.jar

不知道我错过了什么。我是第一次在 Java 和 Spring 中使用 MongoDB，对此的任何帮助将不胜感激。

Answer 1

您的schemaLocation 中缺少http://www.springframework.org/schema/data/mongo。

您的 bean 的最小配置应如下所示：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       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.xsd
        http://www.springframework.org/schema/data/mongo
        http://www.springframework.org/schema/data/mongo/spring-mongo.xsd">

    <mongo:mongo host="localhost" port="27017" id="mongo"/>

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

您也可以考虑放弃 XML 配置，只使用 Java config 来声明 Spring bean。

Answer 2

解决办法是你必须设置mongo:mongo-client而不是mongo:mongo。
