Spring RestTemplate Authentication Basic

Authentication Basic 로 인증되는 서버에서 제공하는 API를 이용 하는 중 Spring RestTemplate 활용 방법

[환경]

Spring-4.1.6

HttpClient-4.3.5

1. 호출 URL 에서 인증 하는 방법

Map<String, Object> resultMap = ezRestTemplate.get("http://admin:1234@localhost:12345/api/overview", HashMap.class);

2. 설정 부분에서 인증 하는 방법

// EzRestTemplate 는 RestTemplate 감쌓놓은 Wrapper Class임.
@Resource EzRestTemplate	ezRestTemplate;

Map<String, Object> resultMap = ezRestTemplate.get("http://localhost:12345/api/overview", HashMap.class);
System.out.println("resultMap: " + resultMap);
