问题

使用Spring OXM + Castor绑定 ，添加了Castor库，但是仍然遇到以下错误消息？

Exception in thread "main" java.lang.RuntimeException: 
	Could not instantiate serializer org.apache.xml.serialize.XMLSerializer: 
	java.lang.ClassNotFoundException: org.apache.xml.serialize.XMLSerializer
	at org.exolab.castor.xml.XercesSerializer.<init>(XercesSerializer.java:50)
	//...

Maven中的Castor依赖关系。

<dependency>
		<groupId>org.codehaus.castor</groupId>
		<artifactId>castor</artifactId>
		<version>1.2</version>
	</dependency>

解

如果没有记错， Castor需要Xerces来工作 ，因此，您还需要添加Xerces依赖项。

<dependencies>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-oxm</artifactId>
			<version>3.0.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.codehaus.castor</groupId>
			<artifactId>castor</artifactId>
			<version>1.2</version>
		</dependency>

		<dependency>
			<groupId>xerces</groupId>
			<artifactId>xercesImpl</artifactId>
			<version>2.8.1</version>
		</dependency>

	</dependencies>
