简单粗暴，直接上代码。

@SuppressWarnings("resource")
        public static String deleteJson(String url, String json, int timeout, Object... objects) throws IOException {
    
            /** * 没有现成的delete可以带json的，自己实现一个，参考HttpPost的实现 */
            class HttpDeleteWithBody extends HttpEntityEnclosingRequestBase {
                public static final String METHOD_NAME = "DELETE";
    
                @SuppressWarnings("unused")
                public HttpDeleteWithBody() {
                }
    
                @SuppressWarnings("unused")
                public HttpDeleteWithBody(URI uri) {
                    setURI(uri);
                }
    
                public HttpDeleteWithBody(String uri) {
                    setURI(URI.create(uri));
                }
    
                public String getMethod() {
                    return METHOD_NAME;
                }
            }
    
            HttpClient httpclient = new DefaultHttpClient();
            httpclient.getParams().setIntParameter("http.socket.timeout", timeout * 1000);
            httpclient.getParams().setBooleanParameter("http.protocol.expect-continue", false);
            String retVal = "";
            try {
                String encoding = HTTP.UTF_8;
                if (objects != null && objects.length > 0) {
                    encoding = objects[0].toString();
                }
                HttpDeleteWithBody httpdelete = new HttpDeleteWithBody(url);
                StringEntity params = new StringEntity(json, encoding);
                httpdelete.addHeader("content-type", "application/json");
                httpdelete.setEntity(params);
                ResponseHandler<String> responseHandler = new BasicResponseHandler();
                if (objects == null || objects.length == 0) {
                    retVal = new String(httpclient.execute(httpdelete, responseHandler).getBytes(HTTP.ISO_8859_1),
                            HTTP.UTF_8);
                } else if (objects != null && objects[0].equals(HTTP.UTF_8)) {
                    retVal = httpclient.execute(httpdelete, responseHandler);
                } else if (objects != null && objects[0].equals("gb2312")) {
                    retVal = new String(httpclient.execute(httpdelete, responseHandler).getBytes("iso-8859-1"), "gb2312");
                } else {
                    retVal = new String(httpclient.execute(httpdelete, responseHandler).getBytes(), HTTP.UTF_8);
                }
            } catch (IOException e) {
                throw e;
            } finally {
                httpclient.getConnectionManager().shutdown();
            }
            logger.debug(retVal);
            return retVal;
        }
