HttpServletRequest获取POST请求Body参数方式
第一种方式
request.getInputStream()
/**
* If the parameter data was sent in the request body, such as occurs
* with an HTTP POST request, then reading the body directly via
* @see javax.servlet.ServletRequest#getInputStream or
* @see javax.servlet.ServletRequest#getReader
* @param request HttpServletRequest
* @return String
*/
public static String getPostData(HttpServletRequest request) {
StringBuilder data = new StringBuilder();
String line;
BufferedReader reader;
try {
reader = request.getReader();
while (null != (line = reader.readLine())) {
data.append(line);
}
} catch (IOException e) {
return null;
}
return data.toString();
}第二种方式
@RequestBody
@RequestMapping(value = "hello", method = {RequestMethod.POST})
@ResponseBody
public String batchDisabledUsers(@RequestBody xxxDTO xx) {
}第三种方式
@RequestParam
@RequestMapping(value = "/testurl", method = RequestMethod.POST)
@ResponseBody
public StringTestUrl(@RequestParam("username")String username,
@RequestParam("pwd")String pwd) {
String txt = username + pwd;
return txt;
}总结
