java springboot 工具类之post、get请求
org.springblade.modules.netprobe.utilsorg.springframework.http.*org.springframework.util.CollectionUtilsorg.springframework.util.MultiValueMaporg.springframework.web.client.RestTemplatejava.util.MapRestTemplateUtil {
RestTemplate =RestTemplate()<>(String urlObject entityClass<> cls){
HttpEntity<Object> request = HttpEntity<>(entity)(urlrequestcls)}
<>(String urlMultiValueMap<StringObject> paramsClass<> cls){
HttpHeaders headers = HttpHeaders()headers.setContentType(MediaType.)HttpEntity<Object> request = HttpEntity<>(paramsheaders)(urlrequestcls)}
<>(String urlHttpEntity<Object> requestClass<> cls){
ResponseEntity<> exchange = .exchange(urlHttpMethod.requestcls)exchange.getBody()}
<>(String urlMap<StringObject> paramsClass<> cls){
StringBuilder urlBuiler=StringBuilder(url)urlBuiler.append()(!CollectionUtils.(params)){
(Map.Entry<StringObject> entry : params.entrySet()) {
urlBuiler.append(entry.getKey()).append().append(entry.getValue()).append()}
}
.getForObject(urlBuiler.toString()cls)}
}post 请求直接调用post方法，传递url、params、返回的类型（可以自定义）
返回的类型，示例如下：
HttpResult {
Integer String BgpValuseDto }
