无法初始化 class com.amazonaws.partitions.PartitionsLoader
Could not initialize class com.amazonaws.partitions.PartitionsLoader
使用 Eclipse Mars。我已经通过从 help.Now 安装软件添加了 aws java sdk 1.11.123 当我 运行 Tomcat Server 7 我得到这个错误:
May 02, 2017 11:57:32 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [PdsServlet] in context with path [/PdsAWS] threw exception [java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.partitions.PartitionsLoader] with root cause java.lang.NoClassDefFoundError: Could not initialize class com.amazonaws.partitions.PartitionsLoader
我也得到
java.lang.NoSuchFieldError: ALLOW_FINAL_FIELDS_AS_MUTATORS
但是当我检查图书馆时，我可以看到 PartitionsLoader.How 这可以解决吗？

Tomcat 有自己的依赖文件。可以在 Eclipse 中配置构建路径并且不将依赖项添加到 build/deploy 的 Tomcat，这可能会导致 Java 抛出该错误。
在 Eclipse 中将您的项目重新创建为动态 Web 项目（如果您不熟悉，请查看有关如何操作的文档）。然后在自动生成的 'WEB-INF/lib' 文件夹中包含任何第 3 方 jar 或库，以及从 Eclipse 中的源代码 运行 所需的构建路径（也就是您现在正在做的方式）。然后，当您准备好部署时，导出到 war 文件，'WEB-INF/lib' 文件夹中的所有必要库将对您的编译源可见。
java.lang.NoSuchFieldError: ALLOW_FINAL_FIELDS_AS_MUTATORS
这听起来就像是从某处挑选旧版本的 Jackson。 PartitionsLoader 在初始化静态成员字段时引用 MapperFeature.ALLOW_FINAL_FIELDS_AS_MUTATORS。如果您在运行时选择的 MapperFeature 版本没有此字段，则由此产生的异常将导致 PartitionsLoader 的 class 初始化过程失败。随后尝试引用 class 将抛出您所看到的异常。
ALLOW_FINAL_FIELDS_AS_MUTATORS 是在 2.2 版本中添加的。您选择哪个版本？
好的，我也遇到过同样的依赖地狱挑战，并且花了很长时间来清理。
以下是我的一组依赖项，需要同步 -
- 经验法则：始终使用相同的 aws sdk 依赖版本（core/s3/ec2 等）
- 使其他依赖项（由 aws 使用）在您的项目中保持一致。
- 这包括我的以下内容
- commons-http 与 AWS 使用的 http-client 冲突
- 删除 commons-http，使用一致的 http-client 和 http-core 版本
- 冲突 fasterxml.jackson 库。使用一致的verison使用
噢。
- 这包括大约 4 个 jar（jackson-databind、核心、注释、cbor）
我过去遇到过同样的问题在我的情况下，我像上面那样设置 pom.xml 并解决了问题
