Spring applicationContext.xml：「根元素之後的文檔中的標記必須是格式正確的」

Question

我通過相同的問題搜索，但不幸找不到解決方案。 我面臨着以下異常：

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.

，這是我的applicationContext.xml：

我不知道異常的原因是什麼... 我感謝您的意見。

關閉<beans>標記，然後添加更多的bean定義。移動關閉beans標籤，使其嵌套bean定義。另一個可以用XML配置文件刻錄你的相關事物是使用IDE中的格式化工具。切勿使用工具格式化XML配置，它可以向xml添加額外的空白，這會解釋爲中斷您的配置。

簡而言之你這樣做：

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

當它應該是這樣的：

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

完全配置變化在於
