问题原因 #

该错误由AWS SDK模块版本不兼容导致：aws-java-sdk-sts模块尝试调用的CLIENT_ENDPOINT字段，在依赖的AWS核心模块（如aws-java-sdk-core）中不存在，说明两者版本不一致。

解决方案 #

• 统一AWS SDK版本：确保所有aws-java-sdk-*开头的依赖使用完全相同的版本，比如将aws-java-sdk-sts和aws-java-sdk-core都指定为1.11.986或同一新版本。
• 排查并排除依赖冲突：
  • 用依赖分析工具查看依赖树：Maven执行mvn dependency:tree，Gradle执行gradle dependencies，找出引入不同版本AWS SDK的依赖项。
  • 对冲突依赖进行排除，例如在pom.xml中排除旧版本的核心模块：

    <dependency>
        <groupId>com.amazonaws</groupId>
        <artifactId>aws-java-sdk-sts</artifactId>
        <version>1.11.986</version>
        <exclusions>
            <exclusion>
                <groupId>com.amazonaws</groupId>
                <artifactId>aws-java-sdk-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    

• 迁移到AWS SDK v2：考虑升级到AWS SDK for Java 2.x，它采用模块化设计，依赖管理更严谨，能从根源避免这类版本冲突问题。
