测试一下代码插件

public WebResult getCategoryListByParentId(Long parentId){
		List<Category> categoryList = this.categoryService.findAllCategoryByParentId(parentId,Constants.COURSE);
        JSONObject jResult = new JSONObject();
        jResult.accumulate("categoryList", categoryList);
        final String finalResultString = jResult.toString();
        JsonResult json = new JsonResult() {
            @Override
            protected void onSerialize(ServletOutputStream outputStream) throws IOException {
                outputStream.write(finalResultString.getBytes("UTF-8"));
            }
        };
        return json;
	}
