添加以下依赖项：

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>secretsmanager</artifactId>
     <version>2.14.7</version>
 </dependency>

  <dependencyManagement>
            <dependencies>
                 <dependency>
                    <groupId>software.amazon.awssdk</groupId>
                    <artifactId>bom</artifactId>
                     <version>2.17.46</version>
                    <type>pom</type>
                </dependency>
    
            </dependencies>
    </dependencyManagement>

您可以在配置数据源时在 spring mvc 项目中使用以下组件。

config.properties

newSecretName= <Set the secret name>
secretValue= <Set the secret value>
modSecretValue= <Set an updated secret value>

        getValue(secretsClient, secretName);
        secretsClient.close();

            GetSecretValueResponse valueResponse = secretsClient.getSecretValue(valueRequest);
            String secret = valueResponse.secretString();
            System.out.println(secret);

        } catch (SecretsManagerException e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
    }
    }
