RestTemplate的getForObject和postForObject方法的使用

@RestController
public class DiscoveryClientController {

    @Autowired
    LoadBalancerClient loadBalancerClient;

    @GetMapping("/test")
    public String test() {
        // 通过spring cloud common中的负载均衡接口选取服务提供节点实现接口调用
        ServiceInstance serviceInstance = loadBalancerClient.choose("alibaba-nacos-discovery-server");
        String url = serviceInstance.getUri() + "/hello?name={name}";
        RestTemplate restTemplate = new RestTemplate();
        String result = restTemplate.getForObject(url, String.class,"hello");
        return result;
    }

    @GetMapping("/spark")
    public String spark() {
        // 通过spring cloud common中的负载均衡接口选取服务提供节点实现接口调用
        ServiceInstance serviceInstance = loadBalancerClient.choose("alibaba-nacos-spark-server");
        String url = serviceInstance.getUri() + "/wordCount?filePath={filePath}";
        RestTemplate restTemplate = new RestTemplate();
        HashMap stringStringHashMap = new HashMap<>();
        stringStringHashMap.put("filePath","D:\IdeaProjects\springboot-learning-experience\spring-boot-spark\wordcount.txt");
        //String result = restTemplate.getForObject(url,String.class,stringStringHashMap);
        String result = restTemplate.postForObject(url,null,String.class,stringStringHashMap);
        return result;
    }
}
