[Java知识库]RestTemplate 根据传参 返回 对象

需求一：根据id，远程调用接口，返回集合

接口提供方

package com.ruoyi.controller.common;

import com.hidata.devops.selfops.domain.OpsResourceList;
import com.hidata.devops.selfops.service.IOpsResourceListService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import com.hidata.devops.selfops.service.IOpsHijobInfoService;

import java.util.ArrayList;
import java.util.List;
import java.util.Map;


@RestController
@RequestMapping("/hiapi")
public class HiApiContoller {

	@Autowired
	private IOpsHijobInfoService opsHijobInfoService;

	/**
	 * 根据nodeId获取ip列表
	 * @param nodeId
	 * @return
	 */
	@RequestMapping("/ip/list")
	public Object getIpListByNodeId(@RequestBody String nodeId){
		return opsResourceListService.getIpListByNodeId(nodeId);
	}
}

接口调用方

String nodeId = "112";
String url = "http://localhost:8180/hiapi/ip/list";
ResponseEntity<List> responseEntity = null;
try {
	responseEntity = restTemplate.postForEntity(url, nodeId, List.class);
} catch (RestClientException e) {
	XxlJobHelper.log(e);
}
		return responseEntity.getBody();

如果要返回对象，那么直接把ResponseEntity 改成 ResponseEntity即可
