Question

我正在使用JEE项目，从Maven项目到Dynamic Web。问题是我没有使用xml配置，但现在，我必须使用Dynamic web项目。

我无法弄清楚如何正确编写applicationContext.xml;我已经阅读了很多主题，但没有人帮助我。

这里有代码和错误：

你能帮我理解吗？谢谢你的建议：）

Answer 1

问题似乎来自上下文文件中bean定义的顺序。

尝试更改以下bean定义的位置

 <tx:annotation-driven transaction-manager="txManager"/>

从好的位置到下面的豆之后。

<context:component-scan base-package="it.**"/>

像

这样的东西

<context:component-scan base-package="it.**"/>
<tx:annotation-driven transaction-manager="txManager"/>

看看这是否解决了您的问题。

供您参考.. http://forum.spring.io/forum/spring-projects/container/9895-order-of-bean-definitions-matters

如果以上解决方案不起作用，我想最后一件事就是检查在你的应用程序的lib文件夹下是否有正确的jar持有指定mongo相关的xsds

我找到了一个解决方案，在 applicationContext.xml 中我只是将一个导入标记放到资源“spring.xml”：

<import resource="spring.xml" />

在 spring.xml 中：

<!-- MongoDB host -->
<mongo:mongo host="localhost" port="27017" />

<!-- Template for performing MongoDB operations -->
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate" c:mongo-ref="mongo" c:databaseName="dbname" />

<!-- Activate Spring Data MongoDB repository support -->
<mongo:repositories base-package="it.domain" mongo-template-ref="mongoTemplate" />

<!-- Use this post processor to translate any MongoExceptions thrown in @Repository annotated classes -->
<bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

现在它开始没有tomcat的崩溃;如果db的连接能正常工作，我会告诉你。

Spring：Mongo配置找不到“mongo：repositories”
