IDEA無法運(yùn)行SpringMVC項目，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IDEA的設(shè)置項：
圖片描述

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

原問題如下：

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

嘗試用IDEA編寫一個簡單的SpringMVC例子，但是一直無法正常運(yùn)行，在幾經(jīng)奮戰(zhàn)之下，已經(jīng)跳過幾個坑，比如JDK版本沖突問題，比如libraries未勾選上等問題。

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

說了這么多，錯誤信息貼出來：

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

如果可以，小弟還想問一下，如何讓IDEA像Eclipse一樣在運(yùn)行時顯示更多關(guān)于Spring容器的日志呢？比如是否加載某個配置文件，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，項目構(gòu)建是否使用了Maven？

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

  1. 從傳統(tǒng)的web項目由eclipse到idea，導(dǎo)入的時候選擇從Eclipse導(dǎo)入
    圖片描述
  2. 導(dǎo)入后手動配置依賴，選擇項目依賴的jdk版本和 項目編譯版本
    圖片描述
    圖片描述
  3. 添加項目中的lib到編譯路徑，右鍵lib
    圖片描述
  4. 如果項目是web項目，如果沒有web模塊，要添加web模塊。打開Project Structure ，選擇Modules，查看要運(yùn)行的Module是否有web模塊，沒有則添加
    圖片描述
  5. 配置web模塊
    在idea中web資源的目錄是web文件夾，如果是eclipse項目web資源的目錄則是WebRoot，點擊Module中項目下的web進(jìn)行更改，改為WebRoot即可。這兩個地方都需要更改。
    圖片描述
  6. 配置Artifacts
    在idea中部署的都是Artifacts。在第4步添加web模塊的時候，添加完成后，對話框右下角是有提示創(chuàng)建Artifact的，選擇創(chuàng)建即可；這里我們手動創(chuàng)建
    圖片描述
  7. 給idea添加tomcat
    圖片描述


    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版本和啟動也有較大關(guān)系。
    圖片描述
    部署項目，添加后給項目配置Application context 路徑，只能有一個/路徑
  8. 添加tomcat依賴
    如果項目中使用了Servlet等 API，如果lib中沒有相關(guān)依賴，我們要添加Tomcat依賴到項目中
    圖片描述
    圖片描述
  9. 啟動項目，即可。

關(guān)于Tomcat運(yùn)行目錄的問題：

這里有三個目錄

  1. Project compiler output
    圖片描述
  2. Module compile out paht
    圖片描述
  3. Artifacts Out directory
    圖片描述

因為Tomcat部署的都是Artifact，所以就是Artifacts Out directory這個路徑。你看一個這個路徑，就知道了。會把項目中編譯好的資源拷貝到這個路徑下。在第一次運(yùn)行的時候，idea也會拷貝的，至于熱加載配置，在前文也提到了。

第一次回答問題，希望可以幫到你。

先回答你誤解的那個設(shè)置：

這里其實沒有什么好解釋，字面意思就很顯然是配置上下文地址的，至于你以為的“瀏覽器默認(rèn)打開這個網(wǎng)址”是這個：

關(guān)于TLD文件問題

你可以參考這里，也許能解決你的問題。

關(guān)于讓IDEA像Eclipse一樣在運(yùn)行時顯示更多關(guān)于Spring容器的日志

你覺得少，首先可能是你項目自身日志配置的問題，詳細(xì)的日志，例如log4j、slf4j等等請自行網(wǎng)上了解。
這里給出spring官方文檔說明：https://docs.spring.io/spring...

還有一種可能是在這里：

以前我也用eclipse，用了IDEA就再也回不去了，不是IDEA非主流，是你沒習(xí)慣。

如果坑實在太多，最簡單的辦法就是你在IDEA新建一個空的maven工程，再把以前的代碼一個個copy過來，這樣出問題的可能性會小很多。
