1、問題描述 

　　我這邊是分為兩個專案 一個分為service 一個分為web 把兩個專案匯入到一個idea裡面 從而不分別啟動。

以我這邊為例子：把service打jar包到web中去

把下面的程式碼複製到service  （也就是你要打為jar包的專案）  pom檔案中

下面程式碼中的這個  <outputDirectory>../sz_smkt_web/src/main/webapp/WEB-INF/lib/</outputDirectory>

路改成你要打jar包的路徑

 <include>**/domain/*</include>

            <include>**/pojo/*</include>

            <include>**/*APProxy*.class</include>

這些是你要打包的檔案型別

 把下方程式碼複製進去
