java中利用RestTemplate给特定接口传特定参数

import com.dykj.common.utils.R;
import org.springframework.http.HttpEntity;
import org.springframework.http.HttpHeaders;
import org.springframework.http.ResponseEntity;
import org.springframework.web.client.RestTemplate;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class Test {

    public static void main(String[] args) {
        RestTemplate restTemplate=new RestTemplate();
        String url="http://localhost:8080/demo/test";//接口url
        //1.map中定义的是请求接口需要的参数 这个url只想要我这边定义的参数
        String[] str=new String[]{"202306150001"};
        Map<String,Object> list=new HashMap<>();
        list.put("type","eq");
        list.put("column","incomeId");
        list.put("value",str);
        List<Map<String,Object>> qmList=new ArrayList<>();
        qmList.add(list);

        map.put("current",1);
        map.put("size",9999);
        map.put("queryMapList",qmList);
        //2.对浏览器请求信息进行的跨域设置以及token参数
        HttpHeaders headers = new HttpHeaders();
        String token = "eyJhbGciOiJIUzUxMiIsInppcCI6IkdaSVAifQ." +
                "H4sIAAAAAAAAAKtWKi5NUrJScon09tINDXYNUtJRSq0oULIyNLMws7SwNDU21VEqLU4t8kwBqjKAAEMliJhfYm4qUPT5uoXPJ7Q9nThDqRYAYjUhhE8AAAA." +

        headers.add("Authorization",token);
        headers.add("Access-Control-Allow-Origin","*");
        headers.add("Access-Control-Allow-Methods","GET, HEAD, POST, OPTIONS");
        headers.add("Access-Control-Allow-Headers","Content-Type");
        //HttpEntity<Map<String,Object>> 中 Map<String,Object>是此url需要请求的对应格式请求参数，这里只想传map集合，你那边要根据你的情况选择
        HttpEntity<Map<String,Object>> request =  new HttpEntity<>(map,headers);
        //利用restTemplate发送数据 post/get/put/delete 这里是post请求
        ResponseEntity<R> forEntity = restTemplate.postForEntity(url,request,R.class);
        System.out.println(forEntity.getBody());//如果有数据 getBody会显示
        //<200,[Vary:"Origin", "Access-Control-Request-Method", "Access-Control-Request-Headers", Content-Length:"0", Date:"Fri, 16 Jun 2023 07:49:48 GMT", Keep-Alive:"timeout=60", Connection:"keep-alive"]>
        //上面的错误是没有配置 HttpHeaders信息或者没传new HttpEntity<>(map,headers) 中的map
    }
