        //获取部门id
        String departmentId = (String)this.getRequest().getParameter("departmentId");
        //根据部门id查询用户list
        List<Admin> adminList = adminService.findAllListBydepartment(departmentId);
        try {
            JsonConfig jsonConfig = new JsonConfig();  //建立配置文件
            jsonConfig.setIgnoreDefaultExcludes(false);  //设置默认忽略
            jsonConfig.setExcludes(new String[]{"roles"}); //此处是亮点，只要将所需忽略字段加到数组中即可
            
            HttpServletResponse response = this.getResponse();
            response.setContentType("text/plain;charset=UTF-8");
            JSONArray array = JSONArray.fromObject(adminList, jsonConfig);
            response.getWriter().print(array);
        } catch (Exception e) {
            e.printStackTrace();
        }
