今天寫代碼時(shí)，發(fā)現(xiàn)HttpServletResponse response = ServletActionContext.getResponse();這句報(bào)紅叉，提示The type javax.servlet.http.HttpServletResponse cannot be resolved. It is indirectly referenced from required .class files，并要求configuration build path，經(jīng)過嘗試之后，發(fā)現(xiàn)解決辦法。

錯(cuò)誤情況：HttpServletResponse response = ServletActionContext.getResponse();這句報(bào)紅叉

提示：The type javax.servlet.http.HttpServletResponse cannot be resolved. It is indirectly referenced from required .class files，并要求configuration build path

解決辦法：點(diǎn)擊提示中的configuration build path（或者右鍵項(xiàng)目，點(diǎn)擊Build Path->configuration build path），打開build path界面后，選擇Libraries選項(xiàng)卡，并單擊Add Library，如圖

選擇MyEclipse Libraries，點(diǎn)擊Next

找到Java EE 5，點(diǎn)擊Finish

再看代碼，紅叉已經(jīng)解決
