Accessing AWS Lambda environment variables in Java code
提问by Java Programmer
The AWS has introduced Environment variables for accessing in the Lambda function. I could not find any documentation which shows how to access the environment variables from the Lambda function using Java. Can anyone help me?

If You are using Spring Core then PropertySourcesPlaceholderConfigurer class can be initialized as a part of Configuration and then @Value("${RESOURCE_URL}") annotation can be used to access environment variables.
如果您使用的是 Spring Core，则可以将 PropertySourcesPlaceholderConfigurer 类初始化为 Configuration 的一部分，然后可以使用 @Value("${RESOURCE_URL}") 注释来访问环境变量。
@Bean
public static PropertySourcesPlaceholderConfigurer placeholderConfigurer() {
return new PropertySourcesPlaceholderConfigurer();
}
@Value("${RESOURCE_URL}")
private String url;
