Spring xd SpringXD无法在Uber Jar'；s库

Spring xd SpringXD无法在Uber Jar'；s库,spring-xd,uberjar,Spring Xd,Uberjar,我在Spring XD中创建了一个自定义模块，其中我使用了Oracle DB并使用ehcache缓存结果。除了XD/lib中存在的jar之外，我在模块中使用了“ehcache-2.9.0.jar和ojdbc6-11.1.0.7.0.jar”。我为自定义模块创建了UBER jar。Uber Jar/lib包含我添加的两个附加Jar。当我在XD env中上载Uber Jar时，模块上载命令运行良好。但是，当我创建流时，我得到java.lang.NoClassDefFoundError:net/sf/

我在Spring XD中创建了一个自定义模块，其中我使用了Oracle DB并使用ehcache缓存结果。除了XD/lib中存在的jar之外，我在模块中使用了“ehcache-2.9.0.jar和ojdbc6-11.1.0.7.0.jar”。我为自定义模块创建了UBER jar。Uber Jar/lib包含我添加的两个附加Jar。当我在XD env中上载Uber Jar时，模块上载命令运行良好。但是，当我创建流时，我得到java.lang.NoClassDefFoundError:net/sf/ehcache/CacheManager。下面给出了堆栈跟踪。如果我将ehcache-2.9.0.jar放在xd/lib文件夹中并重新启动xd，我就能够创建流，但它无法实现uber jar的目的。有什么建议/解决方案吗

我的建议是使用Maven Shaded插件在uber jar中创建一个分解的依赖项。在您的例子中，ehcache位于模块Classloader中，而Spring上下文&Spring上下文支持位于父类加载器上。这将导致bean（类型）注入失败。使用着色插件创建Uber jar，它具有必要的依赖项以及Spring上下文和Spring上下文支持。这个uber jar版本将解决您的问题。

我将研究以下事项

1）如果自定义模块上传正确，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

，看看包含违规类的jar是否确实在Uber jar中

3）如果我正在运行分布式模式，那么我必须确保

自定义模块

文件夹在管理员和容器之间共享，并且容器节点

自定义模块

文件夹具有jar文件。这对于理解必须共享

自定义模块

文件夹，或者管理员和容器之间的目录内容通过外部方式保持同步非常重要-如果您没有将自定义模块文件夹设置为共享文件夹，XD将不会同步该文件夹。
