SpringXD 无法在 Uber Jar 的库中找到 类
SpringXD not able to find classes present in Uber Jar's lib
我在 Spring XD 中创建了一个自定义模块，其中我正在使用 ehcache.Other 访问 Oracle DB 并缓存结果，而不是我正在使用的 xd/lib 中存在的罐子"ehcache-2.9.0.jar and ojdbc6-11.1.0.7.0.jar" 在我的 module.I 中为我的自定义模块创建了 UBER jar。 Uber Jar/lib 包含额外的 jar 我 added.Module 当我在 XD env.How 中上传 uberjar 时，上传命令运行良好，当我创建流时，我得到 java.lang.NoClassDefFoundError: net/sf/ehcache/CacheManager。给出了堆栈跟踪 below.If 我将 ehcache-2.9.0.jar 放在 xd/lib 文件夹中并重新启动 xd 我能够创建流但是它违背了 uber jar 的目的。任何 suggestions/solution?

我的建议是使用 Maven Shaded Plugin 在 uber jar 中创建一个分解的依赖项。在您的情况下，ehcache 在模块类加载器中，Spring-Context & Spring-context-support 在父类加载器中。这将导致 bean(type) 注入失败。使用阴影插件创建具有必要依赖关系的 Uber jar 以及 Spring-Context 和 Spring-context-support。这个uber jar版本可以解决你的问题。
我会调查以下事项
1) 如果自定义模块已正确上传，即如果 uber jar 可用，请检查您的自定义模块文件夹。
2) 我会做一个 jar -vft <jar file name> 来查看包含违规 class 的 jar 是否确实在 Uber jar 中。
3) 如果我是 运行 分布式模式，那么我必须确保 custom-modules 文件夹在管理员和容器之间共享，并且容器节点 custom-modules 文件夹具有 jar 文件.了解必须共享 custom-modules 文件夹或通过外部方式使 admin 和容器之间的目录内容保持同步非常重要 - 如果您尚未设置，XD 将不会同步自定义模块文件夹作为共享文件夹。
