java.lang.ClassNotFoundException: org.apache.commons.beanutils.Converter

当用maven构建struts的web项目时，容器抛出如下错误：

java.lang.ClassNotFoundException: org.apache.commons.beanutils.Converter

经检查，是struts中引用了一个jar包（xml-api）的冲突导致， 所以excluse掉就可以了，如下：

		<dependency>
			<groupId>org.apache.struts</groupId>
			<artifactId>struts-core</artifactId>
			<version>1.3.5</version>
			<exclusions>
				<exclusion>
					<groupId>xml-apis</groupId>
					<artifactId>xml-apis</artifactId>
				</exclusion>
			</exclusions>
		</dependency>

 

That's fine!

缺少commons包引起的错误。加入commons包就没事了
