无法使用resttemplate使用rest api

Question

我正在尝试使用这个api，这是链接https://www.live-rates.com/api/price?key=123456&rate=EUR_USD

我已经在我的控制器中尝试过了

@ResponseBody
    @RequestMapping(value = { "/start" }, method = RequestMethod.GET)
    public String start() { 
RestTemplate restTemplate = new RestTemplate();

        String quote = restTemplate.getForObject("https://www.live-rates.com/api/price?key=123456&rate=EUR_USD", String.class);
        return quote.toString();
    }

在我的日程安排程序中

package com.boilerplate.components;


import java.util.Date;
import org.slf4j.Logger;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Async;

import com.boilerplate.services.MessageListenerService;
import java.util.Random;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.query.Query;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;
import org.springframework.web.client.RestTemplate;

@Repository
@Transactional
@Configuration
@EnableAsync
@EnableScheduling
public class Scheduler {
//Database read and update and delete
    @Autowired
    private RabbitTemplate rabbitTemplate;

    private static final Logger LOGGER = org.slf4j.LoggerFactory.getLogger(MessageListenerService.class);

    @Autowired 
    private SessionFactory sessionFactory;

    @Async
    @Scheduled(cron="*/60 * * * * *")
    public void doSomething(){

        RestTemplate restTemplate = new RestTemplate();

        String quote = restTemplate.getForObject("https://www.live-rates.com/api/price?key=123456&rate=EUR_USD", String.class);
        LOGGER.info(quote.toString());

  }


    }

而他们都没能拿到汇率。

Server Error

为什么我不能使用rest模板获得汇率。

您是否尝试添加下面的代码。您正在尝试使用HTTPS调用。

CloseBleHttpClient httpClient=HttpClients.Custom（）.SetSSLHostNameVerifier（new NoPhostNameVerifier（））.build（）；HttpComponentsClientHttpRequestFactory requestFactory=新的HttpComponentsClientHttpRequestFactory（）；RequestFactory.SetHttpClient（httpClient）；RestTemplate RestTemplate=新建RestTemplate（requestFactoryString quote=restTemplate.getForObject（“https://www.live-rates.com/api/price?key=123456&rate=EUR_USD”，String.class)；
