在http请求中，有Header和Body之分，读取header使用request.getHeader("...");
读取Body使用request.getReader()，但getReader获取的是BufferedReader，需要把它转换成字符串，下面是转换的方法。

public class TestController {
@RequestMapping("/a")
protected void doPost(HttpServletRequest request,
HttpServletResponse response, BufferedReader br)
throws ServletException, IOException {
//Header部分
System.out.print(request.getHeaderNames());
Enumeration<?> enum1 = request.getHeaderNames();
while (enum1.hasMoreElements()) {
String key = (String) enum1.nextElement();
String value = request.getHeader(key);
System.out.println(key + "\t" + value);
}
//body部分
String inputLine;
String str = "";
try {
while ((inputLine = br.readLine()) != null) {
str += inputLine;
}
br.close();
} catch (IOException e) {
System.out.println("IOException: " + e);
}
System.out.println("str:" + str);
}
