SpringMVC接收json对象

请求参数json格式：

{
	"request": {
		"controlinfo ": {
			"sysCode": "xxx",
			"password": "xxx",
			"msgId": "xxx",
			"time": "xxx"
		},
		"param": {
		}
	}
}

解析：

/**
	 * @return 活动创建
	 */
	@RequestMapping(value = "/add", produces = "text/plain;charset=utf-8")
	public String taskInfoAdd(HttpServletRequest request, @RequestBody String reqStr) {
		logger.info("=====TASKINFO ADD======");
		logger.info("REQUEST DATA IS String:" + reqStr);
		ResponseInfo resultInfo = new ResponseInfo();
		ThreadLocalVariable.setTenantId(TENANT_ID);
		try {
			JSONObject reqInfo = new JSONObject(reqStr);
			JSONObject requestInfo = reqInfo.getJSONObject("request");
			JSONObject controlinfo = requestInfo.getJSONObject("controlinfo");
			// 校验权限信息
			boolean isValid = authUtil.validateAuth(controlinfo);
			String tenantId = TENANT_ID;
			if (isValid) {
				// String param = requestInfo.optString("param");
				// JSONObject taskInfoObject = new JSONObject(param);
				JSONObject taskInfoObject = requestInfo.getJSONObject("param");
				// 组装信息
				TObTask taskInfo = new TObTask();
            try {
					taskInfo = this.buildTaskAddInfo(taskInfoObject);
				} catch (Exception e) {
					throw new LengthException();
				}
}

public TObTask buildTaskAddInfo(JSONObject param) throws Exception {
		TObTask taskInfo = new TObTask();
		if (notEmptyStr(param.optString("TASK_NAME"))) {
			taskInfo.setTaskName(param.optString("TASK_NAME"));
		} else {
			throw new Exception("任务名称不能为空");
		}                    

返回参数：

resultInfo.setCode(-1);
				resultInfo.setReason("权限校验失败");
			}

		} catch (Exception e) {
			this.buildError(resultInfo, e);
		}
		return new JSONObject(resultInfo).toString();
