MongoDB SpringMVC整合mongodb 3.0驱动的异常解决

MongoDB springMVC整合mongodb 3.0驱动的异常解决

---

因为业务原因新整合了 mongo 驱动3.0,使用mongoDB的高级查询。并编写了MongoDBUtil工具类。如图为驱动包的maven依赖。

<!-- mongodb java driver --><dependency>   <groupId>org.mongodb</groupId>   <artifactId>mongo-java-driver</artifactId>   <version>3.0.2</version></dependency><!-- Spring data mongodb --><dependency>   <groupId>org.springframework.data</groupId>   <artifactId>spring-data-mongodb</artifactId>   <version>1.8.0.RELEASE</version></dependency>

启动项目时候出现如下错误：

java.lang.NoSuchFieldError: autoConnectRetry

刚开始mongo部分的service注入失败，误以为是jar包冲突。重新加载本地maven仓库,依然报如上错误。

---

仔细研究console的bug信息之后发现下面的错误信息：

Usage of 'mongo-options' is no longer supported for MongoDB Java driver version 3 and above. Please use 'mongo-client-options' and refer to chapter 'MongoDB 3.0 Support' for details

翻译过来就是说使用mongo 3.0驱动之后要将<mongo:mongo改成<mongo:mongo-client对应的

<mongo:options改成<mongo:client-options，还没有结束。

接下来会接着报错 不允许出现属性：'auto-connect-retry'、'slave-ok' 之类的提示

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 33 in XML document from class

path resource [application-config.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber:

33; columnNumber: 25; cvc-complex-type.3.2.2: 元素 'mongo:client-options' 中不允许出现属性 'auto-connect-

retry'。

最终的代码，项目正常运行。

<!-- <mongo:mongo host="127.0.0.1" port="27017"> --><mongo:mongo-client host="192.168.1.105" port="10001"><mongo:client-options connections-per-host="10"threads-allowed-to-block-for-connection-multiplier="5"connect-timeout="10000" socket-keep-alive="false" ></mongo:client-options></mongo:mongo-client>
