Spring：如何从POST主体获取参数？ [英] Spring: How to get parameters from POST body?

问题描述

使用spring的网络服务，我必须从我的帖子请求的正文中获取参数？正文的内容如下： -

Web-service using spring in which I have to get the params from the body of my post request? The content of the body is like:-

source="mysource"

&json=
{
    "items": [
        {
            "username": "test1",
            "allowed": true
        },
        {
            "username": "test2",
            "allowed": false
        }
    ]
}

网络服务方法如下： -

And the web-service method looks like:-

@RequestMapping(value = "/saveData", headers="Content-Type=application/json", method = RequestMethod.POST)
    @ResponseBody
    public ResponseEntity<Boolean> saveData(@RequestBody String a) throws MyException {
        return new ResponseEntity<Boolean>(uiRequestProcessor.saveData(a),HttpStatus.OK);

    }

请告诉我如何从中获取参数身体？我可以把整个身体放在我的绳子里，但我认为这不是一个有效的方法。请告诉我如何进一步处理。

Please let me know how do I get the params from the body? I can get the whole body in my string but I don't think that would be a valid approach. Please let me know how do I proceed further.

推荐答案

您可以从请求中获取参数。

You can get param from request.

@ResponseBody
public ResponseEntity<Boolean> saveData(HttpServletRequest request,
            HttpServletResponse response, Model model){
   String jsonString = request.getParameter("json");
}
