今天在修改Controller的類(lèi)名之后出現(xiàn)了個(gè)令我十分費(fèi)解的有關(guān)tomcat問(wèn)題柠偶。
出現(xiàn)問(wèn)題的過(guò)程：我先是在我的分支上修改了NoviceLoginController的名字，改為了NoviceLoginRewardController之后，提交了代碼灾部，并且合到了測(cè)試環(huán)境，ps aux |grep xxx找到該api的進(jìn)程號(hào)，kill掉之后startup? tomcat然后就開(kāi)始無(wú)限的彈出這個(gè)錯(cuò)誤了。我懷疑是tomcat的啟動(dòng)時(shí)太抓，代碼中同時(shí)存在改名前和改名后兩個(gè)文件，從而導(dǎo)致出現(xiàn)了兩個(gè)相同的@RequestMapping地址令杈。但是不知道為什么會(huì)出現(xiàn)這種情況走敌。
問(wèn)題詳情如下：
