关于URLEncoder.encode的用法

公司项目需要访问jira平台，需要对传输数据进行转码，否则乱码导致查询出错。

# 一、前端代码 #

//获取系统和相应系统的领域负责人
      function getSystem(){ 
      	$.ajax({ 
            url : '${pageContext.request.contextPath}/IT00015Controller/doGet.action',
            type : 'get',
            async : false,
            data : { 
            	   url: 'http://***.***.com/rest/insight/1.0/iql/objects?objectSchemaId=21&iql=objectTypeId=266'
            },
            dataType : 'json',
            success : function (result) { 
            	systemManager = result;
            }
          });
      }

这里将"服务名称"中文字符转换成了

%E7%B3%BB%E7%BB%9F%E5%B7%A5%E5%85%B7

# 二、Controller层 #

@RequestMapping("/doGet")
        @ResponseBody
        public List<Map<String,Object>> doGet(String url) { 
            Session session = SecurityUtils.getSubject().getSession();
            try { 
                String objectType = URLEncoder.encode("服务名称", "UTF-8");
                URL urlStr = new URL(url + objectType + "&resultPerPage=500");
                List<Map<String, Object>> result = it00015Service.doGet(urlStr,"s-servicedesk:BenDan11");
                return result;
            } catch (IOException e) { 
                e.printStackTrace();
            }
            return null;
        }

Service层

public List<Map<String,Object>> doGet(URL urlStr, String token) { 
            HttpURLConnection connection = null;
            InputStream is = null;
            BufferedReader br = null;
            String result = null;// 返回结果字符串
            List<Map<String,Object>> maps = new ArrayList<>();
            try { 
                // 通过远程url连接对象打开一个连接，强转成httpURLConnection类
                connection = (HttpURLConnection) urlStr.openConnection();
                connection.setRequestProperty("Content-Type","application/json;charset=UTF-8");
                connection.setRequestProperty("accept", "*/*");
                connection.setRequestProperty("connection", "Keep-Alive");
                connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
                connection.setDoInput(true);
                connection.setDoOutput(true);
                connection.setRequestProperty("Authorization","Basic " + new Base64Encoder().encode(token.getBytes()));
                //connection.setRequestProperty("Authorization","Basic " + new Base64Encoder().encode("60055859:169533#A".getBytes()));
                // 设置连接方式：get
                connection.setRequestMethod("GET");
                // 设置连接主机服务器的超时时间：15000毫秒
                connection.setConnectTimeout(15000);
                // 设置读取远程返回的数据时间：60000毫秒
                connection.setReadTimeout(600000);
                // 发送请求
                connection.connect();
                // 通过connection连接，获取输入流
                if (connection.getResponseCode() == 200) { 
                    is = connection.getInputStream();
                    // 封装输入流is，并指定字符集
                    br = new BufferedReader(new InputStreamReader(is, "UTF-8"));
                    // 存放数据
                    StringBuilder sbf = new StringBuilder();
                    String temp = null;
                    while ((temp = br.readLine()) != null) { 
                        sbf.append(temp);
                        sbf.append("\r\n");
                    }
                    result = sbf.toString();
                    Map<String,Object> map = JSON.parseObject(result);
    
                    JSONArray jsonArray = new JSONArray(map.get("objectEntries").toString());

                        for(int j = 0;j <jsonArray1.length();j++ ){ 
                            //生产环境
                            if(("2345").equals(jsonArray1.getJSONObject(j).get("objectTypeAttributeId").toString())){

                                    map2.put("owner",jsonArray2.getJSONObject(0).get("displayValue").toString());
                                }
                                break;
