如何在WebService中获取当前UserviewMenu插件的配置项

$.ajax({
    url:"${request.contextPath}/web/json/plugin/com.vps.menu.ShortcutButton/service?uvId="+UI.userview_id,
    data:{},
    method:'GET',
    dataType:'text',
    async:false,
    success:function(html){
        console.log("html",html)
        
    },
    error:function(err){
        console.error("err",err)
    }
})

String uvId = httpServletRequest.getParameter("uvId");
Map<String, Object> properties = getUserviewPropertiesByUserviewId(httpServletRequest,uvId);
