spring mvc 集成resttemplate

RestTemplate，Spring Web提供的轻量级HTTP Client，用于简化HTTP调用。

RestTemplate restTemplate = new RestTemplate();
String replay = restTemplate.getForObject("http://localhost:8080/get",String.class);
System.out.println(replay);

//占位符
replay = restTemplate.getForObject("http://localhost:8080/test/{id}",String.class,1);

获取相应码

ResponseEntity<String> responseEntity = restTemplate.getForEntity(url,String.class);
System.out.println(responseEntity.getBody());
System.out.println(responseEntity.getStatusCode());

发生post请求

RequstObject requestObject =  RequstObject.builder()
        .age(10)
        .name("abc")
        .build();
responseEntity = restTemplate.postForEntity(url,requestObject,String.class);
System.out.println(responseEntity.getBody());
System.out.println(responseEntity.getStatusCode());

spring集成如下

@Bean
public RestTemplate restTemplate(){
    return new RestTemplate();
}
