原因

子項目與副項目的web.xml文件下重複出現了jar包，並且版本不一致。導致版本衝突。

//子項目下的pom.xml
		<dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>5.0.3.RELEASE</version>
            <scope>compile</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>5.0.3.RELEASE</version>
            <scope>compile</scope>
        </dependency>

//父項目下個的pom.xml
	<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
        <!-- spring版本號 -->
        <spring.version>5.0.2.RELEASE</spring.version>
        <!-- mybatis版本號 -->
        <mybatis.version>3.2.6</mybatis.version>
        <!-- log4j日誌文件管理包版本 -->
        <slf4j.version>1.7.7</slf4j.version>
        <log4j.version>1.2.17</log4j.version>
        <c3p0.version>0.9.5.2</c3p0.version>

解決方法

將子項目中的重複部分刪除即可
