本文详细介绍了使用 CXF 框架发布 REST 服务时遇到的 URL 中文显示问题和参数编码问题，并提供了相应的解决方法。通过兼容处理，解决了浏览器访问与 HttpURLConnection 访问之间的差异，确保了服务的稳定性和兼容性。

用cxf 发部个rest服务，用浏览器访问和 HttpURLConnection 访问。

1. URL中有中文，浏览器访问正常，HttpURLConnection 失败。

解决： HttpURLConnection 方式需要做兼容处理。

queryParam 传入参数，服务实现方法中要处理，如果是乱码要转换，如果中文直接查询

if (!isChineseChar(queryParam))
 {
      queryParam = new String(queryParam.getBytes("iso8859-1"), "utf-8");
 }

// 判断中文
public static boolean isChineseChar(String str)
    {
        boolean temp = false;
        Pattern p=Pattern.compile("[\u4e00-\u9fa5]");
        Matcher m=p.matcher(str);
        if(m.find()){
            temp =  true;
        }
        return temp;
    }

2. HttpURLConnection 请求中参数中如果有空格，请求则会 505错误

解决：需要对有空格的参数做URL编码处理。

    public static void main(String[] args) 
    {
        JSONObject obj = new JSONObject();
        obj.put("XM", "匡匡");

        String urls = targetURL + obj.toString();

             HttpURLConnection httpConnection = (HttpURLConnection) restServiceURL.openConnection();

             httpConnection.setRequestProperty("Accept", "application/json");
             httpConnection.setRequestProperty("Accept-Charset", "UTF-8");

             if (httpConnection.getResponseCode() != 200) {
                    throw new RuntimeException("HTTP GET Request Failed with Error code : "
                                  + httpConnection.getResponseCode());
             }
            
             BufferedReader responseBuffer = new BufferedReader(new InputStreamReader(
                    (httpConnection.getInputStream()),"utf-8"));

             String output = "";
             String result = "";
             System.out.println("Output from Server:  \n");

             while ((output = responseBuffer.readLine()) != null) {
                    //System.out.println(output);
                    result = output;
             }
             obj = JSONObject.parseObject(result);
             System.out.println(obj.toString());
             httpConnection.disconnect();

        } catch (MalformedURLException e) {

             e.printStackTrace();

        } catch (IOException e) {
             e.printStackTrace();

        }
         return obj;
    }
    
    @SuppressWarnings("deprecation")
    <span style="color:#FF6666;">private static String getURLEncoder(String dest)
    {
        return URLEncoder.encode(dest);
    }</span>
}

修改后正常ok
