Eclipse用maven構建SSM框架遇到的問題及解決方法
聽說Maven很好用,剛剛好實驗了Spring+Mvc企業應用實踐的一個小專案,所以就拿它來練手了,用maven來重構它。
開發環境如下:
Eclipse:Eclipse Project Release Notes 4.7 (Oxygen)
JDK:JDK1.8.0_144
Maven:apache-maven-3.5.4
Tomcat:Tomcat 9
環境的配置就不多說了,其實只要有目錄就行,Eclipse中配好就可以了
首先新建Maven專案,如果是第一次建Maven專案的話,一定要確保網路狀態良好,因為任何下載中斷或者下載錯誤都會導致建立Maven專案失敗。
這裡選webapp
建立完成就報錯了,Could not resolve archetype org.apache.maven.archetypes:maven-archetype-webapp:1.0 from any of the configured repositories.可以看出是倉庫的問題
原因是archetype錯誤,去maven倉庫刪掉它的最後更新檔案,重新建就會再下了
建立成功,專案目錄如下
先把jdk換一下,因為我之前改了maven的settings.xml,所以直接1.8了,不然是1.5
新增的語句如下
<profile> <id>jdk-1.8</id> <activation> <activeByDefault>true</activeByDefault> <jdk>1.8</jdk> </activation> <properties> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion> </properties> </profile>
再新增tomcat9配置
看一下Project Facet,發現是Module版本是2.3
先不改,直接執行一下,成功了
在網上看了一些資料,說servlet和這個module是有對應版本的,還是把它改高一些把
再開啟
再執行,tomcat報了錯
再次執行,能成功進去了
接下來先改web.xml,因為改成3.1了,而web.xml裡的宣告還是2.3,直接刪掉就行了
如果你不刪會怎麼樣呢,我被這個錯誤弄了好久,哈哈Description Resource Path Location Type
Cannot change version of project facet Dynamic Web Module to 2.3. fkbookapp-maven line 1 Maven Java EE Configuration Problem
pom.xml新增一些依賴

Update一下,它會自動下載jar包到倉庫
建立src/main/java目錄存java檔案
匯入專案內容
結果:
哈哈哈,烏蠅哥
