Stacktrace:] with root cause

java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'mlisBasicinfo' available as request attribute

緣由：form表單中的modelAttribute="mlisBasicinfo" 沒法獲取到，加載頁面是直接到jsp頁面，沒有modelAttribute，

解決：先通過controller類，再到jsp頁面的，可在controller類中添加@ModelAttribute 的get方法

@ModelAttribute

    public MlisBasicinfo get(@RequestParam(required = false) String id) {

        MlisBasicinfo entity = null;

        if (StringUtils.isNotBlank(id)) {

            entity = mlisBasicinfoService.get(id);

        }

        if (entity == null) {

            entity = new MlisBasicinfo();

        }

        return entity;

    }
