Spring MVC获取HTTP请求的body方式

1、通过字符流或字节流获取

@ApiOperation("desc")
@RequestMapping(value = "/api", method = {RequestMethod.GET, RequestMethod.POST}, produces = "application/json;charset=UTF-8")
public RespData<Boolean> api(
        HttpServletRequest request,
        HttpServletResponse response) {
    BufferedReader br = request.getReader();
    String str, body = "";
    while((str = br.readLine()) != null){
        body += str;
    }
    log.info(body);

}

@ApiOperation("desc")
@RequestMapping(value = "/api", method = {RequestMethod.GET, RequestMethod.POST}, produces = "application/json;charset=UTF-8")
public RespData<Boolean> api(
        HttpServletRequest request,
        HttpServletResponse response) { int length = request.getContentLength();
        ServletInputStream input = request.getInputStream();
        byte[] buffer = new byte[length];
        input.read(buffer, 0, length);
        log.info(new String(buffer));

}

2、通过字@RequestBody获取

@ApiOperation("desc")
@RequestMapping(value = "/api", method = {RequestMethod.GET, RequestMethod.POST}, produces = "application/json;charset=UTF-8")
public RespData<Boolean> api(@ApiParam(value = "id", required = false) @RequestParam(value = "id",required = false) Long id,@RequestBody String body,
        HttpServletRequest request,
        HttpServletResponse response) {
   log.info("body---->{}",body);
}
