我们已经使用 eclipse 构建了一个 spring-batch 应用程序。每当我通过 eclipse 执行程序时，它都运行良好。但是当我尝试生成并运行使用 ant 创建的 jar 文件时，我得到了这个难看的堆栈跟踪。

我已经在这上面花了超过 3 天的时间，但无济于事。我已确保我制作的 xsd 引用与我使用的 spring jar 版本兼容。
如有任何帮助，我们将不胜感激。
相同的 launch-context.xml 在 eclipse 中工作，它在通过给定的 ant build.xml 构建时抛出此错误。
我正在尝试将所有相关的 jar 打包到一个 fat jar 中。我遇到过一些暗示我不能那样做的帖子。要引用打包的 jar，我需要 one-jar 或 eclipse 的 jarinjarloader。否则我将不得不将依赖 jar 放在我的主 jar 之外。如果这是真正的问题，我会尝试这些选项并返回。同时，如果您对此编辑有任何意见，请更新您的答案，我会将其标记为正确。
最佳答案
您选择的 XML 编辑器/验证器是否成功验证了您的应用程序上下文(您称为启动上下文的那个)？它无效，因为 http://www.springframework.org/schema/batch/spring-batch-2.1.xsd 无效。
但是，您发布的内容(只是摘录吗？)甚至不需要 batch 命名空间。因此，您可以删除它，从而将它变成有效的 XML。

我有一个模型:classItem项目有一个属性“商店”基于存储的值，我希望Item对象对特定方法具有不同的行为。Rails中是否有针对此的通用设计模式？如果方法中没有大的if-else语句，这是如何干净利落地完成的？ 最佳答案 通常通过Single-TableInheritance. 关于ruby-on-rails-Rails-子类化模型的设计模式是什么？，我们在StackOverflow上找到一个类似的问题： https://stackoverflow.co
大约一年前，我决定确保每个包含非唯一文本的Flash通知都将从模块中的方法中获取文本。我这样做的最初原因是为了避免一遍又一遍地输入相同的字符串。如果我想更改措辞，我可以在一个地方轻松完成，而且一遍又一遍地重复同一件事而出现拼写错误的可能性也会降低。我最终得到的是这样的:moduleMessagesdefformat_error_messages(errors)errors.map{|attribute,message|"Error:#{attribute.to_s.titleize}#{message}."}enddeferror_message_could_not_find(obje
我主要使用Ruby来执行此操作，但到目前为止我的攻击计划如下:使用gemsrdf、rdf-rdfa和rdf-microdata或mida来解析给定任何URI的数据。我认为最好映射到像schema.org这样的统一模式，例如使用这个yaml文件，它试图描述数据词汇表和opengraph到schema.org之间的转换:#SchemaXtoschema.orgconversion#data-vocabularyDV:name:namestreet-address:streetAddressregion:addressRegionlocality:addressLocalityphoto:i

我有一个对象has_many应呈现为xml的子对象。这不是问题。我的问题是我创建了一个Hash包含此数据，就像解析器需要它一样。但是rails自动将整个文件包含在.........我需要摆脱type="array"和我该如何处理？我没有在文档中找到任何内容。 最佳答案 我遇到了同样的问题；这是我的XML:我在用这个:entries.to_xml将散列数据转换为XML，但这会将条目的数据包装到中所以我修改了:entries.to_xml(root:"Contacts")但这仍然将转换后的XML包装在“联系人”中，将我的XML代码修改为
