我正在尝试执行下面的推土机示例。我的 xml 文件与我的 java 文件位于相同的位置，但我得到了找不到文件的异常

Exception in thread "main" org.dozer.MappingException: Unable to locate dozer mapping file [dozerMapping.xml] in the classpath!
    at org.dozer.util.MappingUtils.throwMappingException(MappingUtils.java:87)
    at org.dozer.util.MappingValidator.validateURL(MappingValidator.java:63)

    at org.dozer.DozerBeanMapper.map(DozerBeanMapper.java:111)
    at com.mapping.CopyAttributes.main(CopyAttributes.java:28)

如果我提供完整的文件路径，它正在工作，但我得到以下异常

源代码

    String file = "C:/UnitTest/Dozer/src/com/mapping/mapping.xml";
    DozerBeanMapper mapper = new DozerBeanMapper(Arrays.asList(new String[]{file}));

好的。我解决了这个..

我将文件放入resources/META-INF/dozerBeanMapping.xml并使用以下方法访问该文件：

String file = "META-INF/dozerBeanMapping.xml";

DozerBeanMapper mapper = new DozerBeanMapper(Arrays.asList(new String[]{file}));

我希望这对你们也有帮助。

您正在使用String file = "C:/..."并且错误提到它不能将 C 识别为有效协议。

您应该尝试file://C:/...改用 - 它可能会有所帮助。如果没有，请尝试使用双反斜杠 ( C:\\UnitTest\\...)，如果这不起作用，只需将文件上传到某处
