具有不同树的同一个jar的依赖关系

Question

我正试图用弹簧罐来解决一个问题。我用很旧的罐子做一个很老的项目。

对于一个项目，我的依赖树拥有Spring 2.0.1，而对于另一个项目，它现在拥有Spring 2.0.2。它们都是依赖于一个jar :spring core:jar:1.0m3。

我遇到的问题是下面的例外:原来ClassUtils从2.0.1更改为2.0.2，而忽略了这个方法。：

ERROR [org.springframework.web.context.ContextLoader] (ServerService Thread Pool -- 94) Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityLoadJob' defined in class path resource [dri-applicationContext.xml]: Instantiation of bean failed; nested exception is java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.getConstructorIfAvailable(Ljava/lang/Class;[Ljava/lang/Class;)Ljava/lang/reflect/Constructor;

在我的poms中，我没有为Spring和Spring定义任何版本，我定义的唯一版本是父Pom中的org.springframework.ws:spring-ws-core:jar:1.0-m3:compile。

现在，拥有相同jar的两个项目如何能够拥有完全不同的依赖jar。我在Maven3，wildfly9，java8。

而且，奇怪的是，相同的war文件在我的本地windows wildfly9上运行良好，但它在SunOS和Linux机器上给我带来了错误。

编辑:我从NoSuchMethodError for XmlSchemaCollection.read()那里得到了NoSuchMethodError for XmlSchemaCollection.read()的想法，用它我找到了两个罐子。正如Harini所建议的，我已经尝试了排除依赖关系，但它仍然没有工作，所以我只是重构了我的代码，使其只有一个src，而且在战争中也是如此(在野苍蝇中，war用它自己的类加载器加载它的库)，所以在重构之后，我也遇到了同样的问题：

我是如何知道这是jar问题的，我对jvm做了详细的介绍，并看到了以下内容：

从vfs:/content/DirectRegistryServlet-1.0-SNAPSHOT.war/WEB-INF/lib/spring-core-2.0.1.jar加载org.springframework.util.ClassUtils

Answer 1

看一下我正在使用的org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean代码，它实际上是导致问题的原因，在春季2.0.1中，这个FactoryBean并没有提到ClassUtils.getConstructorIfAvailable，这是很好的。正是Spring-2.0.2或spring-support-2.0.2.jar也有这个类，这个行就是这个调用所在的地方。

(我看错了类，因为问题是MethodInvokingJobDetailFactoryBean来自不同的jar，而不是Spring2.0.1.jar，spring 2.0.1实际上使用spring，它使用spring-support2.0.2.jar，它具有相同的MethodInvokingJobDetailFactoryBean )所以我解决了它:只创建了一个库来删除库，或者排除了也有这个类并解决它的库。

奇怪的是，我无法理解在windows上，它是如何在没有问题的情况下工作的，而在Linux和unix上，它给出了一个问题。

Answer 2

在spring core:jar:1.0-m3依赖项中，不包含spring核心版本，而您不是using.Check，它是针对依赖项排除的。
