工程模塊和模塊劃分
將ssm這個(gè)項(xiàng)目分模塊（前面三個(gè)南顾牵快的創(chuàng)建不需要用到模板，直接創(chuàng)建空的maven）

把上面的劃分成下面的模塊

首先ssm_dao分離
點(diǎn)擊如下：

創(chuàng)建一個(gè)新模塊：

其他步驟就是創(chuàng)建maven項(xiàng)目
下面是創(chuàng)建好的項(xiàng)目棍好，只需要將domain的類導(dǎo)入，其他都不需要，沒(méi)有配置

compile編譯一下看是否成功
ssm_dao的分離

創(chuàng)建一個(gè)新的模塊
然后把文件導(dǎo)入進(jìn)去
