查询activiti流程定义转换为json抛出的异常

请问这个错误如何解决，查询activiti流程定义转换为json抛出的异常

转换json数组的时候出问题了 贴下代码看看

你可以将这个processDefinition属性过滤掉

你先看看查出来的数据是什么，打个断点看看。

// 查看已部署的流程定义列表
@RequestMapping(value = "/process-list", method = { RequestMethod.GET, RequestMethod.POST })
@ResponseBody
public ResultMsg processList(HttpServletRequest request)
{
    try
    {
        List<Map<String, Object>> list = new ArrayList<>();
        Map<String, Object> map;

        ProcessDefinitionQuery processDefinitionQuery = activitiService.getProcessDefinitionQuery();
        List<ProcessDefinition> processDefinitionList = processDefinitionQuery.list();

        for (ProcessDefinition pd : processDefinitionList)
        {
            map = new HashMap<>();
            map.put("processDefinitionId", pd.getId());
            map.put("deploymentId", pd.getDeploymentId());
            map.put("name", pd.getName());
            map.put("key", pd.getKey());
            map.put("version", pd.getVersion());
            map.put("resourceName", pd.getResourceName());
            map.put("diagramResourceName", pd.getDiagramResourceName());
            map.put("deploymentTime", activitiService.getSingleDeployment(pd.getDeploymentId()).getDeploymentTime());
            list.add(map);
        }
        return new ResultMsg(ResultCode.SUCCESS, "获取流程定义列表成功", list);
    }
    catch (Exception e)
    {
        e.printStackTrace();
        return new ResultMsg(ResultCode.SYSTEM_INNER_ERROR, "获取流程定义列表失败", null);
    }
}
