Java 创建Springbean时未知属性accessExternalDTD

我继承了一个旧的（15年）Java应用程序，它维护得很差。Mavenizing没有正确完成，所以我尝试了一下，因为有很多库是手动添加到类路径的。现在我有了一个主pom，它将所有库作为pom文件中的依赖项

错误如下：

调用init方法失败；嵌套异常为java.lang.IllegalArgumentException:未知属性

但现在我在启动Web服务时遇到了一些解析器问题。旧项目使用的是用于XML的SaxParser，但它也使用Spring，我在初始化bean时看到冲突

我已经升级到Java8（也在Liberty配置文件上运行，因为我们使用IBMJDK8绑定到IBM）。添加了jaxp api以获取类路径上的“accessExternalDTD”属性。删除了xerces实现（也从xalan依赖项中排除），但没有任何效果

我在谷歌上搜索了很多，但都找不到任何方法来启动这个旧的应用程序。希望有人遇到过同样的问题，并能告诉我如何处理。

您的问题似乎与之相关，它是在spring ws 3.0.6.0版本中引入的。您需要改用3.0.7.BUILD-SNAPSHOT。

尝试从JDK 8安装TransformerFactory。JBoss中存在一个问题，但是代码快照应该以同样的方式工作

我在一个旧代码中遇到了同样的问题，在旧代码中，删除SaxonJ或其他依赖项是不可能的

最后，我添加了一个系统属性来定义要实例化的默认TransformerFactory：

-Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

---

注意：示例是使用OpenJDK8，您必须找到所需的

TransformerFactoryImpl

包

看看这个，谢谢，这确实解决了我的问题。现在我必须等待3.0.7.0版本，因为我不允许在配置中使用快照存储库（公司规则）。
