import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpEntity;

@Service
@Slf4j
public class TestServiceImpl implements TestService
@Autowired
private RestTemplate restTemplate;
private final String URL = "http://15.15.82.127:8124/api/test/getData";
private final String USER_NAME = "test";
private final String PASS_WORD = "test123";
@Override
public String getData()
//1、构建body参数
JSONObject jsonObject = new JSONObject();
jsonObject.put("UserName",USER_NAME);
jsonObject.put("Password",PASS_WORD);
//2、添加请求头
HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type","application/json");
//3、组装请求头和参数
HttpEntity<String> formEntity = new HttpEntity<String>(JSON.toJSONString(jsonObject), headers);
//4、发起post请求
ResponseEntity<String> stringResponseEntity = null;
try
stringResponseEntity = restTemplate.postForEntity(URL, formEntity, String.class);
log.info("ResponseEntity----"+stringResponseEntity);
catch (RestClientException e)
e.printStackTrace();
//5、获取http状态码
int statusCodeValue = stringResponseEntity.getStatusCodeValue();
log.info("httpCode-----"+statusCodeValue);
//6、获取返回体
String body = stringResponseEntity.getBody();
log.info("body-----"+body);
//7、映射实体类
Wrapper wrapper = JSONObject.parseObject(body, Wrapper.class);
String data = wrapper.getData();
log.info("data-----"+data);
return data;
