Dozer文件未找到异常

Question

我正在尝试执行下面的推土机示例。我的xml文件与我的java文件位于同一个位置，但是我得到的文件没有找到异常。

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.loader.CustomMappingsLoader.loadFromFiles(CustomMappingsLoader.java:101)
    at org.dozer.loader.CustomMappingsLoader.load(CustomMappingsLoader.java:56)
    at org.dozer.DozerBeanMapper.loadCustomMappings(DozerBeanMapper.java:213)
    at org.dozer.DozerBeanMapper.getMappingProcessor(DozerBeanMapper.java:186)
    at org.dozer.DozerBeanMapper.map(DozerBeanMapper.java:111)
    at com.mapping.CopyAttributes.main(CopyAttributes.java:28)

如果我给出了完整的文件路径，它就能工作了，但是我得到了下面的异常

Exception in thread "main" org.dozer.MappingException: java.net.MalformedURLException: unknown protocol: c

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..。

我将该文件放入resources/META-INF/dozerBeanMapping.xml并通过以下方法访问该文件：

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

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

希望这也能帮到你们。
