Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/biz-context.xml]; nested exception is java.lang.IllegalStateException: Annotation-specified bean name 'sysParamDAO' for bean class [com.focoon.agilecollab.generated.dao.impl.SysParamDAOImpl

解析 biz-context.xml时报异常 ，说是 sysParamDAO是无效参数异常
