IDEA無(wú)法運(yùn)行SpringMVC項(xiàng)目，提示No TLD files were found in

2017年12月27日 01：08更新

我剛剛誤解了一個(gè)IDEA的設(shè)置項(xiàng)：
圖片描述

我以為這是“瀏覽器默認(rèn)打開(kāi)這個(gè)網(wǎng)址”的意思，結(jié)果是給項(xiàng)目加前綴，導(dǎo)致一直404，但是我還是很好奇我問(wèn)的問(wèn)題的答案，希望有朋友愿意幫我解答，謝謝。

原問(wèn)題如下：

小弟剛從Eclipse轉(zhuǎn)戰(zhàn)到IDEA平臺(tái)，可以說(shuō)是諸事不順。

嘗試用IDEA編寫(xiě)一個(gè)簡(jiǎn)單的SpringMVC例子，但是一直無(wú)法正常運(yùn)行，在幾經(jīng)奮戰(zhàn)之下，已經(jīng)跳過(guò)幾個(gè)坑，比如JDK版本沖突問(wèn)題，比如libraries未勾選上等問(wèn)題。

但是還是無(wú)法順利的完成，在Google與baidu的搜索之下，也沒(méi)有找到合適的資料，所以希望能夠借助各位的幫助。

說(shuō)了這么多，錯(cuò)誤信息貼出來(lái)：

備注一點(diǎn)：同樣的配置，在Eclipse中可以完美運(yùn)行（包含幾個(gè)主要的配置文件，以及共用的Maven，Tomcat等）

如果可以，小弟還想問(wèn)一下，如何讓IDEA像Eclipse一樣在運(yùn)行時(shí)顯示更多關(guān)于Spring容器的日志呢？比如是否加載某個(gè)配置文件，還有IDEA的運(yùn)行目錄能不能不要那么非主流？直接放在Tomcat的webapps下面呢？

感謝！

首先需要明確一點(diǎn)，項(xiàng)目構(gòu)建是否使用了Maven？

從項(xiàng)目使用了lib目錄感覺(jué)不是
/E:/IDEA/myProjectName/target/myProjectName/WEB-INF/lib/spring-webmvc-5.0.1.RELEASE.jar

從傳統(tǒng)的web項(xiàng)目由eclipse到idea，導(dǎo)入的時(shí)候選擇從Eclipse導(dǎo)入
導(dǎo)入后手動(dòng)配置依賴，選擇項(xiàng)目依賴的jdk版本和項(xiàng)目編譯版本
添加項(xiàng)目中的lib到編譯路徑，右鍵lib
如果項(xiàng)目是web項(xiàng)目，如果沒(méi)有web模塊，要添加web模塊。打開(kāi)Project Structure ，選擇Modules，查看要運(yùn)行的Module是否有web模塊，沒(méi)有則添加
配置web模塊
在idea中web資源的目錄是web文件夾，如果是eclipse項(xiàng)目web資源的目錄則是WebRoot，點(diǎn)擊Module中項(xiàng)目下的web進(jìn)行更改，改為WebRoot即可。這兩個(gè)地方都需要更改。
配置Artifacts
在idea中部署的都是Artifacts。在第4步添加web模塊的時(shí)候，添加完成后，對(duì)話框右下角是有提示創(chuàng)建Artifact的，選擇創(chuàng)建即可；這里我們手動(dòng)創(chuàng)建
給idea添加tomcat

如果需要熱加載需要更改On Update action和 On frame deactivatioin 為 Update classes and resources
Tomcat依賴的JDK版本和啟動(dòng)也有較大關(guān)系。

部署項(xiàng)目，添加后給項(xiàng)目配置Application context 路徑，只能有一個(gè)/路徑
添加tomcat依賴
如果項(xiàng)目中使用了Servlet等 API，如果lib中沒(méi)有相關(guān)依賴，我們要添加Tomcat依賴到項(xiàng)目中
啟動(dòng)項(xiàng)目，即可。

關(guān)于Tomcat運(yùn)行目錄的問(wèn)題：

這里有三個(gè)目錄

Project compiler output
Module compile out paht
Artifacts Out directory

因?yàn)門(mén)omcat部署的都是Artifact，所以就是Artifacts Out directory這個(gè)路徑。你看一個(gè)這個(gè)路徑，就知道了。會(huì)把項(xiàng)目中編譯好的資源拷貝到這個(gè)路徑下。在第一次運(yùn)行的時(shí)候，idea也會(huì)拷貝的，至于熱加載配置，在前文也提到了。

第一次回答問(wèn)題，希望可以幫到你。
