需跳转接口

	@RestController
	@CrossOrigin
	@PostMapping("/gotoCarkeeper")
    public void gotoCarkeeper(HttpServletResponse response) throws IOException {
        Member member = memberMapper.selectByPrimaryKey(UserUtils.getThisMobileUser().getId());
        WxMpUserConfig wxUser = wxMpUserMapper.findWxUserByMemberId(member.getMemberId());
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("member",member);
        jsonObject.put("wxUser",wxUser);
        doPost(jsonObject);
    }

    public static JSONObject doPost(JSONObject date) {
        HttpClient client = HttpClients.createDefault();
        // 要调用的接口方法
        String url = "http://localhost:8082/weixin/chichengToLocal";
        HttpPost post = new HttpPost(url);
        JSONObject jsonObject = null;
        try {
            StringEntity s = new StringEntity(date.toString());
            s.setContentEncoding("UTF-8");
            s.setContentType("application/json");
            post.setEntity(s);
            post.addHeader("content-type", "text/xml");
            HttpResponse res = client.execute(post);
            
            /** 以下都是该端口需要做处 理所需要的一些数据 **/
            String response1 = EntityUtils.toString(res.getEntity());
            System.out.println(response1);
            if (res.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                String result = EntityUtils.toString(res.getEntity());// 返回json格式：
                jsonObject = JSONObject.parseObject(result);
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
        return jsonObject;
    }

跳转接口（接收方）

	@CrossOrigin
    @RequestMapping("chichengToLocal")
    public String chichengToLocal(@RequestBody String content){
        JSONObject json = (JSONObject) JSONObject.parse(content);
        String member = json.getString("member");
        String wxUser = json.getString("wxUser");
        return "index";
    }

以上就是SpringBoot 不同端口后台跳转(带参)的使用教程，有问题的小伙伴可以评论区或私信提出！
