曾经我遇到的异常们

Caused by: org.xml.sax.SAXParseException: cos-all-limited.1.2: An ''all'' model group must appear in a particle with '{'min occurs'}'='{'max occurs'}'=1, and that particle must be part of a pair which constitutes the '{'content type'}' of a complex type definition.

--Spring4.1.1（3.1）和commons-dbcp1.2.1冲突，解决方案commons-dbcp改为1.4版本。
