使用 restTemplate 实现get/post 请求

get 请求（这里是在 idea 的 test包中，所以需要直接 new RestTemplate() ）

即：RestTemplate restTemplate = new RestTemplate();

package org.darkblue.monitor;

import org.junit.Test;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

public class TestTemplate {

    @Test
    public void test() {
        RestTemplate restTemplate = new RestTemplate();

        HttpHeaders headers = new HttpHeaders();
        MultiValueMap<String, String> postParameters = new LinkedMultiValueMap<String, String>();
        HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<MultiValueMap<String, String>>(postParameters, headers);
        String str = restTemplate.postForObject("http://192.168.1.15/DETECT-X/", requestEntity, String.class);

        System.out.println(str.toString());

    }

}

post 请求（这里是在非test包中，所以可以自动注入）：

package org.darkblue.monitor.controller;

import com.kinome.surveillance.web.dao.RepoDao;
import com.kinome.surveillance.web.dao.RepoDaoImp;
import com.kinome.surveillance.web.entity.RepoEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.stereotype.Controller;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.client.RestTemplate;

import javax.servlet.http.HttpServletRequest;
import java.util.List;

@Controller
public class CensorStatusController {

    @Autowired
    HttpServletRequest request;
    @Autowired
    RestTemplate restTemplate;

    @ResponseBody
    @RequestMapping("updateCensorStatus")
    public String updateCensorStatus(RepoEntity re) {

        RepoDao repoDao = new RepoDaoImp();
        RepoEntity repoEntity = new RepoEntity();
        int intCensorStatus = re.getCensorStatus();
        int intRid = re.getRid();
        System.out.println("intRid =========> " + intRid);
        List<RepoEntity> repoByRid = repoDao.getRepoByRid(intRid);
        for (RepoEntity rbr :
                repoByRid) {
            repoEntity.setPtLink(rbr.getPtLink());
            repoEntity.setRemark(rbr.getRemark());
        }

        if (re.getCensorStatus() == 2) {
            repoDao.deleteRid(intRid);

            int userId = (int) request.getSession().getAttribute("userId");
            HttpHeaders headers = new HttpHeaders();
            headers.add("X-Auth-Token", "e348bc22-5efa-4299-9142-529f07a18ac9");

            MultiValueMap<String, String> postParameters = new LinkedMultiValueMap<String, String>();
            postParameters.add("item0_1", repoEntity.getPtLink());
            postParameters.add("item0_2", repoEntity.getRemark());
            postParameters.add("userid", String.valueOf(userId));

            HttpEntity<MultiValueMap<String, String>> requestEntity = new HttpEntity<MultiValueMap<String, String>>(postParameters, headers);

            String str = restTemplate.postForObject("http://localhost:8080/DETECT-X/BulkAddPtLinkAndRemark.action", requestEntity, String.class);
//        System.out.println(str.toString());
            return "1";
        } else {
            if (repoDao.setCensorStatusByRid(intCensorStatus, intRid)) {
                return "1";
            } else {
                return "0";
            }
        }

    }

}
