使用Spring+iBatis开发，测试是发生如下异常，百思不得其解啊！求高人指点
`Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlMapClient' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is org.springframework.core.NestedIOException: Failed to parse config resource: class path resource [sql-map-config.xml]; nested exception is com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: java.lang.RuntimeException: Error parsing XPath '/sqlMapConfig/sqlMap'. Cause: com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 1; 文件提前结束。`
以下是我的代码
