我們正在將我們的應用程式從 Spring Boot 版本 2.6.7 升級到 2.7.0，并且在應用程式啟動時開始出現錯誤：
java.sql.SQLException: Identity plugin 'AWS-IAM' is used without having AWS SDK in classpath. Please add 'software.amazon.awssdk:rds' to classpath
我們已經添加了以下依賴項：
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-rds</artifactId>
<version>1.12.221</version>
</dependency>
代碼中沒有進行其他更改。有想法該怎么解決這個嗎？

uj5u.com熱心網友回復：
Spring Boot 2.7 已經從 2.7.x 升級到 3.0.x 的mariadb-java-client. 在 3.0.x 中，他們對AwsIamCredentialPlugin. 以前，它會尋找存在，com.amazonaws.auth.BasicAWSCredentials但現在會尋找software.amazon.awssdk.auth.credentials.AwsBasicCredentials不同模塊中的存在。
正如例外訊息所暗示的，添加依賴項software.amazon.awssdk:rds應該可以解決問題。2.17.199是撰寫本文時的最新版本：
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>rds</artifactId>
<version>2.17.199</version>
</dependency>
