1,分析

2， interface层

E3Result upadateContentCategory(long id, String name);
    E3Result deleteContentCategory(long id);

3，service层

/** * 重命名分类 */
    @Override
    public E3Result upadateContentCategory(long id, String name) {
        // 建立一个tb_content_category表对应的pojo对象
        TbContentCategory node = contentCategoryMapper.selectByPrimaryKey(id);
        // 更新名字
        node.setName(name);
        contentCategoryMapper.updateByPrimaryKey(node);
        return null;
    }

    /** * 删除分类 */
    @Override
    public E3Result deleteContentCategory(long id) {
        TbContentCategory contentCategory = contentCategoryMapper.selectByPrimaryKey(id);
        if (contentCategory.getIsParent()) {
            List<EasyUITreeNode> list = getContentCatList(id);
            // 递归删除
            for (EasyUITreeNode tbcontentCategory : list) {
                deleteContentCategory(tbcontentCategory.getId());
            }
        }
            if (getContentCatList(contentCategory.getParentId()).size() == 1) {
                TbContentCategory parentCategory = contentCategoryMapper
                        .selectByPrimaryKey(contentCategory.getParentId());
                parentCategory.setIsParent(false);
                contentCategoryMapper.updateByPrimaryKey(parentCategory);
            }
            contentCategoryMapper.deleteByPrimaryKey(id);
            return E3Result.ok();

        }

4， controller层

@RequestMapping("/update")
    @ResponseBody
    public E3Result update(Long id, String name) {
        E3Result result = contentCategoryService.upadateContentCategory(id, name);
        return result;
    }

    @RequestMapping("/delete")
    @ResponseBody
    public E3Result update(Long id) {
        E3Result result = contentCategoryService.deleteContentCategory(id);
        return result;
    }
