无法读取架构文档 spring xsd

Question

我知道这是一个常见问题，但我尝试了很多这里已经提出的解决方案，但没有一个有效：/

我有一个在旧的 Jboss 4.2.3 上运行的现有项目。 所以我将它迁移到 Wildfly 8。我在项目中的 pom.xml 中配置了 4.0.6 spring 版本。

在我的 databaseBeans.xml 中，我在迁移之前配置了 2.5 版本的 xsd，所以我放了新版本：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">

    <bean id="mappingList" class="java.util.ArrayList">

但我得到：

我也尝试删除 -4.0.xsd 让 spring 选择但同样的错误：

在此堆栈跟踪（spring-beans-4.0.6.RELEASE.jar:4.0.6.RELEASE）末尾列出的 jar 中，我检查了 META-INF/spring.schemas 并且我有：

我做错了什么？

编辑 ：

我尝试调试代码，当读取 XML 时，我发现 Jboss 版本和 Wildly 版本之间存在差异。

带有“UnifiedClassLoader”的 Jboss 版本中加载了十几个“包”（包括 spring-beans 和其他东西）：

带有“ModuleClassLoader”的 Wildfly 版本只有 2 个包，而不是 spring-beans jar：

我的 App 的两个文件似乎有问题：1 个 war 和 1 个 .ear 文件。

.ear 文件不像 Jboss 那样加载，并且错过了 spring 依赖项。

但是为什么在堆栈跟踪中我们看到这种情况下提到的“spring-beans-4.0.6.RELEASE.jar”？

Answer 1

我按照本教程成功解决了问题：

https://access.redhat.com/solutions/168093

简而言之，我创建了一个 modules/org/springframework/spring/main/module.xml 文件，其中包含资源中的 spring jar。 我将已经存在于服务器上的 tmp/deployment/vfs 中的 spring jar 复制到此目录中：modules/org/springframework/spring/main/ 然后我在我的应用程序中创建一个 jboss-deployment-structure 并添加 spring 模块。

但是，我真的不明白为什么我需要做所有这些，为 Wildfly 创建一个弹簧模块......等等

spring 是项目的依赖，jar 是可用的，那么为什么不能像这样简单地工作呢？
