如果遇到報錯405，PUT http://localhost:9090/uploads/.........
只需要在文件服務(wù)器中的 web.xml 中加入下面的代碼

重點來了~
idea中springmvc跨服務(wù)器上傳文件報405錯誤，修改了web.xml一樣報錯
這個問題是因為你使用的文件服務(wù)器的Tomcat使用的是exploded模式部署，修改的Tomcat本地conf下的web.xml對exploded的項目沒有生效，此時應(yīng)該使用war包模式進行部署，本地修改的web.xml文件繼續(xù)保持修改狀態(tài)，并且修改Application context不為/，可以修改為：/+任意文件名
然后再重新部署一下Tomcat服務(wù)器，此時不再報錯。（注意要修改一下代碼中的文件上傳路徑）
以上為個人經(jīng)驗，希望能給大家一個參考，也希望大家多多支持服務(wù)器之家。
