今天整合SSH，出現(xiàn)了這個(gè)問(wèn)題Context initialization failed，很是郁悶。

這里主要提示：
Error creating bean with name 'headsService' defined in ServletContext resource [/WEB-INF/classes/applicationContext-heads.xml]: Initialization of bean failed; nested exception is org.springframework.beans.InvalidPropertyException: Invalid property 'hDao' of bean class 



我找了好久錯(cuò)誤的原因，但都沒(méi)有找到。
后面，我干脆講“hDao”改為“dao”，整個(gè)程序就能運(yùn)行起來(lái)了。
很是無(wú)奈，想了好久還是想不明白。
