問題描述

我有一個多模塊maven項目： parent-proj ，它有兩個子模塊： child-dao-proj和child-web-proj 。 child-dao-proj是一個Maven Java項目，而child-web-proj是一個Web項目。 在pom父項目中，我聲明了兩者都需要的所有必需依賴項： 

 <modelVersion>4.0.0</modelVersion>
<groupId>fr.myproject</groupId>
<artifactId>parent-proj</artifactId>
<version>1.0-SNAPSHOT</version>
<modules>
    <module>child-dao-proj</module>
    <module>child-web-proj</module>
</modules>
<packaging>pom</packaging>

        </dependency>
    </dependencies>
</dependencyManagement>

我將所有必需的持久性jar（休眠，spring-orm，spring-data等）的依賴項放在child-dao-proj並將所有web jar（spring-mvc，spring-web等）放入child-web-proj 。

當我運行mvn clean install並在Tomcat中部署Web項目時，遇到以下錯誤： java.lang.ClassNotFoundException:org.springframework.web.context.ContextLoaderListener 。

搜索后，似乎彈簧罐未復制到WEB-INF/lib目錄中。

有人知道我該如何解決這個問題？

[編輯]這是Web項目的pom： 

<parent>
    <artifactId>parent-proj</artifactId>
    <groupId>fr.myproject</groupId>
    <version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>

<packaging>war</packaging>

        <groupId>org.assertj</groupId>
        <artifactId>assertj-core</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

我忘了提到我正在與Intellij合作。

這是處理您的情況的正確方法：

您可以在您的父部分的dependencyManagement中導入spring-framework-bom，以確保所有spring依賴項處於相同版本。 

    <dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-framework-bom</artifactId>
            <version>4.1.0.BUILD-SNAPSHOT</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

在您的戰爭項目中，您可以通過以下方式聲明依賴關系： 

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-web</artifactId>
    </dependency>
<dependencies>

這樣，您可以避免對每個彈簧模塊重復使用彈簧版本
