尋找示例代碼以從 aws 參數存儲中讀取參數值

Question

尋找示例 java 代碼以從 aws 參數存儲中讀取參數存儲值，如 RDS 連接字符串。 appreicate 代碼或任何參考鏈接。 謝謝。

Answer 1

下面是從 AWS 參數存儲中讀取特定參數值的 V2（非 V1）示例：

import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.ssm.SsmClient;
import software.amazon.awssdk.services.ssm.model.GetParameterRequest;
import software.amazon.awssdk.services.ssm.model.GetParameterResponse;
import software.amazon.awssdk.services.ssm.model.SsmException;

public class GetParameter {

    public static void main(String[] args) {

        final String USAGE = "\n" +
                "Usage:\n" +
                "    GetParameter <paraName>\n\n" +
                "Where:\n" +
                "    paraName - the name of the parameter\n";

        if (args.length < 1) {
            System.out.println(USAGE);
            System.exit(1);
         }

        // Get args
        String paraName = args[0];

        Region region = Region.US_EAST_1;
        SsmClient ssmClient = SsmClient.builder()
                .region(region)
                .build();

        try {
            GetParameterRequest parameterRequest = GetParameterRequest.builder()
                .name(paraName)
                .build();

            GetParameterResponse parameterResponse = ssmClient.getParameter(parameterRequest);
            System.out.println("The parameter value is "+parameterResponse.parameter().value());

        } catch (SsmException e) {
        System.err.println(e.getMessage());
        System.exit(1);
        }
   }
}

import com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagement;
import com.amazonaws.services.simplesystemsmanagement.AWSSimpleSystemsManagementClientBuilder;
import com.amazonaws.services.simplesystemsmanagement.model.GetParametersRequest;
import com.amazonaws.services.simplesystemsmanagement.model.GetParametersResult;

...

private static AWSSimpleSystemsManagement ssmclient = AWSSimpleSystemsManagementClientBuilder
            .standard().withRegion(System.getProperty("SystemsManagerRegion")).build();

...

GetParametersRequest paramRequest = new GetParametersRequest()
                .withNames(parameterName).withWithDecryption(encrypted);
        GetParametersResult paramResult = new GetParametersResult();
        paramResult = ssmclient.getParameters(paramRequest);

Answer 3

我認為 GitHub 可能會有幫助。 我搜索了SsmClient getParameter language:java ，一些結果看起來很有希望。

這個例如：

    public static String getDiscordToken(SsmClient ssmClient) {
        GetParameterRequest request = GetParameterRequest.builder().
                name("/discord/token").
                withDecryption(Boolean.TRUE).
                build();
        GetParameterResponse response = ssmClient.getParameter(request);
        return response.parameter().value();
    }
