求指教:Property 'mapperLocations' was not specified or no matching resources found

剛接觸 ssm 框架, 然后今天在看了老師的視頻之后,自己動(dòng)手跑單元測(cè)試的時(shí)候出現(xiàn):

Property 'mapperLocations' was not specified or no matching resources found


下面是幾個(gè)主要的配置文件

主要的代碼如上, 請(qǐng)教一下各位前輩,是不是哪里配置出錯(cuò)了?還是我寫錯(cuò)了? ?多謝前輩指導(dǎo)..
