枚举 AWSConfigConstants.CredentialProvider

java.lang.Object

java.lang.Enum<AWSConfigConstants.CredentialProvider>

org.apache.flink.connector.aws.config.AWSConfigConstants.CredentialProvider

所有已实现的接口:

Serializable, Comparable<AWSConfigConstants.CredentialProvider>

封闭类:

AWSConfigConstants

public static enum AWSConfigConstants.CredentialProvider
extends Enum<AWSConfigConstants.CredentialProvider>

Possible configuration values for the type of credential provider to use when accessing AWS. Internally, a corresponding implementation of AwsCredentialsProvider will be used.

枚举常量概要

枚举常量

枚举常量和说明
ASSUME_ROLE Create AWS credentials by assuming a role.
AUTO A credentials provider chain will be used that searches for credentials in this order: ENV_VARS, SYS_PROPS, WEB_IDENTITY_TOKEN, PROFILE in the AWS instance metadata
BASIC Simply create AWS credentials by supplying the AWS access key ID and AWS secret key in the configuration properties.
ENV_VAR Look for the environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to create AWS credentials.
PROFILE Use a AWS credentials profile file to create the AWS credentials.
SYS_PROP Look for Java system properties aws.accessKeyId and aws.secretKey to create AWS credentials.
WEB_IDENTITY_TOKEN Use AWS WebIdentityToken in order to assume a role.

方法详细资料

values

public static AWSConfigConstants.CredentialProvider[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (AWSConfigConstants.CredentialProvider c : AWSConfigConstants.CredentialProvider.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static AWSConfigConstants.CredentialProvider valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值
