java调用其它服务接口并传参（亲测有效）

以spring Boot 为例 ：

1.引入jar包，pom.xml

   
            commons-httpclient
            commons-httpclient
            3.1
  

2.controller层直接调用即可

@GetMapping("sendPost")
    public String sendPost(){
        HttpClient client = new HttpClient(); 	 //创建Client
        PostMethod method=null;
        String result="";
        try {
            method = new PostMethod("换成你自己的路径");
            method.setParameter("id", "{id:12131}");// 设置参数
            client.executeMethod(method);
            if (method.getStatusCode() == HttpStatus.SC_OK) {// 响应成功
                result = method.getResponseBodyAsString();// 调用返回结果
                return result;
            } else {// 不成功组装结果
              return "error";
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return  null;
    }

	@RequestMapping(value = "/test",method = RequestMethod.POST)
	@ResponseBody
	public String test(String id){
        System.out.println(id);
		return "success"; 
	}

亲测有效，工作记录
