解决Spring中使用context:component-scan命名空间配置错误

** nested exception is org.xml.sax.SAXParseException; lineNumber: 16; columnNumber: 74; cvc-complex-type.2.4.c: 通配符的匹配很全面, 但无法找到元素 ‘context:component-scan‘ 的声明。

原因:Spring命名空间配置错误，缺少相应的spring-bean。
解决：
<?xml version="1.0" encoding="UTF-8"?>
<beans** xmlns="http://www.springframework.org/schema/beans"**
xmlns:amq="http://activemq.apache.org/schema/core"
