controller接收httpclient请求

1. 如果controller放在现有的项目中， 要绕过登录验证
2. 要responseBody返回xml需要配置applicationContext-mvc配置文件增加<mvc:annotation-driven/>
3. 实体类加xml注解

@Controller@RequestMapping("appTestVpn")public class AppTestVpnController  extends BaseController{    @RequestMapping(value="testVpn",method=RequestMethod.POST)      @ResponseBody          public Coffee testVpn() {        try {            BufferedReader in = new BufferedReader(new InputStreamReader(request.getInputStream(),Charset.forName("GBK")));            StringBuilder sb1 = new StringBuilder();            String line = null;            while ((line = in.readLine()) != null) {               sb1.append(line);            }            String jstr=sb1.toString();             //读取客户端发送来的信息            System.err.println(jstr);        } catch (IOException e) {            e.printStackTrace();        }        System.err.println("ssss");        Coffee coffee = new Coffee("蓝山", 100);        return coffee;    }}
