Tomcat容器启动失败，找到 debug日志一看:
Context initialization failed
org.springframework. beans.factory.xml.XmlBeanDefinitionStoreException:Line 1 in XML document from file [spring-wlf.xml] is invalid;nested exception is org.xml.sax.SAXParseException:The processing instruction target matching "[xX][mM][1L]” is not allowed.
回头打开spring-wlf.xml仔细看了下
<?xml version="1.0" encoding="UTF-8"?>
竟然在文件开头多了一个空格，导致识别不了文件。不得不承认，有时候问题就是这么纠结而细微:在<?xml前面有个不起眼的空格。
