開發(fā)工具是ECLIPSE，由于是MAVEN WEB項(xiàng)目，不是ECLIPSE項(xiàng)目，測(cè)試用的如TOMCAT就不能使用平常的ECLIPSE加TOMCAT的方式了。只能用MAVEN的TOMCAT插件。
MAVEN的這個(gè)TOMCAT插件其實(shí)就是讓MAVEN去啟動(dòng)一個(gè)內(nèi)嵌的TOMCAT服務(wù)器，如果項(xiàng)目和這個(gè)TOMCAT關(guān)聯(lián)了，項(xiàng)目就可以部署上去。
內(nèi)嵌的服務(wù)器功能擴(kuò)展，是通過(guò)插件的配置進(jìn)行的。如改端口等，一些復(fù)雜的功能如增加數(shù)據(jù)源，就要配置自定義的server.xml了，但配置了這個(gè)后，插件的所有功能都被覆蓋了，如context.xml也無(wú)效了，代碼改變，自動(dòng)重啟TOMCAT等功能也沒(méi)有了。
數(shù)據(jù)源只能配在context.xml中，作用范圍只在該WEB APP內(nèi)。
費(fèi)話不多說(shuō)，上菜：

context.xml，src\main\webapp\META-INF\context.xml。這樣的配置，各個(gè)競(jìng)價(jià)如JSP、WEB-INF/classes、lib可以在不同的地方，類路徑會(huì)取MAVEN的類輸出路徑，lib會(huì)取MAVEN引用的lib。

web.xml加上這一段：

這樣使用命令
mvn tomcat7:run
即可運(yùn)行了。
