Spring applicationContext.xml：“根元素后面的文档中的标记必须格式正确”

Question

我搜索了同样的问题，但不幸的是我找不到解决方案。 我面临以下例外：

    Exception in thread "main" org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 32 in XML document from class path resource [applicationContext.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 32; columnNumber: 2; The markup in the document following the root element must be well-formed.

这是我的applicationContext.xml：

我不知道异常的原因是什么...... 感谢您的评论。

关闭<beans>标记，然后添加更多bean定义。移动结束beans标记，使其嵌套bean定义。另一个可以使用XML配置文件刻录您的相关内容是使用IDE中的格式工具。永远不要使用工具格式化XML配置，它可以为xml添加额外的空格，这会被解释为破坏您的配置。

简而言之，你这样做：

<beans>
    <bean id="1"/>
</beans>
<bean id="2"/>
<bean id="3"/>

应该是这样的：

<beans>
   <bean id="1"/>
   <bean id="2"/>
   <bean id="3"/>
</beans>

完整配置更改
