最新和旧版本冲突的两个 Maven 依赖关系

问题描述

我正在使用 here 的 spring-data-dynamoDB 项目，根据其 pom.xml 他们使用了 1.6.9.1 版本的 aws-java-sdk，但我需要为我的项目使用最新版本的 aws-java-sdk，以便使用它的一些功能来实现 Amazon s3.如果我包含它的依赖项，

Am using spring-data-dynamoDB project from here, as per its pom.xml they have used 1.6.9.1 version of aws-java-sdk, but I need to use latest version of aws-java-sdk for my project for using some of its features to implement Amazon s3 too. If I include its dependency,

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>1.7.9</version>
</dependency>

我得到如下异常，

12:51:25.298 [main] DEBUG o.s.b.f.s.DefaultListableBeanFactory - Retrieved dependent beans for bean '(inner bean)': [_relProvider]
12:51:25.307 [main] ERROR o.s.w.c.ContextLoader - Context initialization failed

我尝试了以下排除方法，结果也一样，

I have tried exclusions as follows and also the same result,

<dependency>
   <groupId>org.socialsignin</groupId>
   <artifactId>spring-data-dynamodb</artifactId>
   <version>1.0.0-SNAPSHOT</version>
   <exclusions>
      <exclusion>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk</artifactId>
      </exclusion>
   </exclusions>
</dependency>

现在可以在我的项目中使用最新版本的 aws-java-sdk 吗?否则 spring-data-dynamoDB pom.xml 必须更新，如果只有我能够使用它还是什么?感谢 Michaellavelle 完成了这个巨大的项目.它对我完成 DynamoDB 部分有很大帮助.

Is it possible to use latest version of aws-java-sdk in my project now?? or else spring-data-dynamoDB pom.xml have to be updated if so only I am able to use it or what?? Thanks Michaellavelle for that tremendous project. It helps me alot for completing DynamoDB part.

推荐答案

谢谢@user944849.问题是 aws-java-sdk 中使用的 jackson 库，它是 spring-data-rest-webmvc 中的较低版本并与之冲突，因此通过从 aws-java-sdk 中排除 jackson 库构建正确.我得到的解决方案是，

Thanks you @user944849. The problem is jackson libs used in aws-java-sdk which is lower version as of in spring-data-rest-webmvc and conflicts with it, so by excluding jackson libs from aws-java-sdk builds correct. Solution I got is,

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
    <version>1.7.9</version>
    <exclusions>
        <exclusion>
            <artifactId>jackson-core</artifactId>
            <groupId>com.fasterxml.jackson.core</groupId>
        </exclusion>
        <exclusion>
            <artifactId>jackson-databind</artifactId>
            <groupId>com.fasterxml.jackson.core</groupId>
        </exclusion>
        <exclusion>
            <artifactId>jackson-annotations</artifactId>
            <groupId>com.fasterxml.jackson.core</groupId>
        </exclusion>
    </exclusions>
</dependency>
