spring mvc下http发送和接收xml请求

spring mvc下http发送和接收xml请求

本文主要介绍，如何在spring mvc框架下，配合swagger插件，通过http，发送和接受xml请求。

1、通过control编写，接收xml请求的接口，

其中@RequestBody标签，主要存放xml body中的内容看直接传xml内容

其中@RequestHeader  存放xml中的头部内容，主要用于接口安全性校验

2、swagger接口界面，便于用户使用，代码如下：

3、通过http，发送xml请求。

    public String doPostByContent(String url, String param) throws Exception {
        

        StringBuffer parameterBuffer = new StringBuffer();
        parameterBuffer.append(param);
        URL localURL = new URL(url);
        URLConnection connection = openConnection(localURL);
        HttpURLConnection httpURLConnection = (HttpURLConnection)connection;
        httpURLConnection.setDoOutput(true);
        httpURLConnection.setRequestMethod("POST");
        httpURLConnection.setRequestProperty("Content-type", "application/json;charset=UTF-8");
        httpURLConnection.setRequestProperty("Accept-Charset", charset);
        httpURLConnection.setRequestProperty("Content-Length", String.valueOf(parameterBuffer.length()));
        OutputStream outputStream = null;
        InputStream inputStream = null;
        InputStreamReader inputStreamReader = null;
        BufferedReader reader = null;
        StringBuffer resultBuffer = new StringBuffer();
        String tempLine = null;
        
        try {
        	//String s = parameterBuffer.toString();
            outputStream = httpURLConnection.getOutputStream();
            byte[]data = parameterBuffer.toString().getBytes();
            outputStream.write(data);
            if (httpURLConnection.getResponseCode() >= 300) {
                throw new Exception("HTTP Request is not success, Response code is " + httpURLConnection.getResponseCode());
            }
            
            inputStream = httpURLConnection.getInputStream();
            inputStreamReader = new InputStreamReader(inputStream,"utf-8");
            reader = new BufferedReader(inputStreamReader);
            
            while ((tempLine = reader.readLine()) != null) {
                resultBuffer.append(tempLine);
            }
            
        } finally {
            
            if (outputStream != null) {
                outputStream.close();
            }
            
            if (reader != null) {
                reader.close();
            }
            
            if (inputStreamReader != null) {
                inputStreamReader.close();
            }
            
            if (inputStream != null) {
                inputStream.close();
            }
            
        }

        return resultBuffer.toString();
    }
