今天來記錄一下自己在整合框架過程中所遇到的問題:
創(chuàng)新互聯(lián)服務(wù)項(xiàng)目包括渠縣網(wǎng)站建設(shè)、渠縣網(wǎng)站制作、渠縣網(wǎng)頁制作以及渠縣網(wǎng)絡(luò)營銷策劃等。多年來,我們專注于互聯(lián)網(wǎng)行業(yè),利用自身積累的技術(shù)優(yōu)勢(shì)、行業(yè)經(jīng)驗(yàn)、深度合作伙伴關(guān)系等,向廣大中小型企業(yè)、政府機(jī)構(gòu)等提供互聯(lián)網(wǎng)行業(yè)的解決方案,渠縣網(wǎng)站推廣取得了明顯的社會(huì)效益與經(jīng)濟(jì)效益。目前,我們服務(wù)的客戶以成都為中心已經(jīng)輻射到渠縣省份的部分城市,未來相信會(huì)繼續(xù)擴(kuò)大服務(wù)區(qū)域并繼續(xù)獲得客戶的支持與信任!
1. 在用redis實(shí)現(xiàn)session共享時(shí),項(xiàng)目啟動(dòng)報(bào) No bean named 'springSessionRepositoryFilter' is defined 異常
2. 在調(diào)用緩存工具類的時(shí)候顯示注入的JedisPool為Null (一個(gè)跟spring掃描有關(guān)的細(xì)節(jié)錯(cuò)誤)
好了,開始上我整合的文件了
pom.xml依賴jar包

以上是整合的配置文件,其中有關(guān)redis的配置是整合成功的關(guān)鍵
問題總結(jié)
1.之前整合完啟動(dòng)項(xiàng)目報(bào)異常,是因?yàn)榕渲梦募胖玫奈恢脝栴},以至于啟動(dòng)不成功,多試幾遍,以上的配置文件是可以用的
2.之前調(diào)用緩存工具類,顯示注入JedisPool為空,在controller那邊注入又有值,是因?yàn)槲以赾ontroller那邊調(diào)用工具類的方式是new出來的,所以導(dǎo)致spring在掃描那個(gè)工具類時(shí)丟失Jedispool注入,在controller中改用注入工具類的形式即可解決
例如:
