log4j:ERROR 无法解析 url [file://.../mda/log4j.xml]

Question

我正在开发一个使用 Maven、andromda 3.4、CXF Web 服务和 Uml 1.4 的项目。

在我开始使用 Web 服务之前一切正常。我已经用 Webservice 刻板印象正确标记了分类，用 XmlSchema 标记了包。

然而，当我运行 mvn install 时，出现以下异常：

'wsgenjava:
     [echo] running wsdlvalidator for AndroMDA generated wsdl for service OrganisationService

有人知道这个问题是怎么回事吗？

Answer 1

如果您为文件定义的 URL 是 Linux/Unix 系统中的绝对路径，那么您需要在协议后添加一个额外的正斜杠。

例如

file://home/junior/Documents/business/jrsystems/devel/tsaditiro/main-app/mda/../mda/log4j.xml

应该是：

file:///home/junior/Documents/business/jrsystems/devel/tsaditiro/main-app/mda/../mda/log4j.xml

log4j:ERROR 无法解析 url [file://.../mda/log4j.xml]

log4j:ERROR Could not parse url [file://.../mda/log4j.xml]

java

web-services

cxf

maven

andromda
