博客管理控制层：

管理员控制层：
/** * @author yy */ @Controller @RequestMapping("/admin") public class CategoryController { @Resource private CategoryService categoryService; /** * @param request * @return java.lang.String */ @GetMapping("/categories") public String categoryPage(HttpServletRequest request) { request.setAttribute("path", "categories"); return "admin/category"; } /** * @param params * @return com.hbu.myblog.util.Result */ @RequestMapping(value = "/categories/list", method = RequestMethod.GET) @ResponseBody public Result list(@RequestParam Map<String, Object> params) { if (StringUtils.isEmpty(params.get("page")) || StringUtils.isEmpty(params.get("limit"))) { return ResultGenerator.genFailResult("参数异常！"); } PageQueryUtil pageUtil = new PageQueryUtil(params); return ResultGenerator.genSuccessResult(categoryService.getBlogCategoryPage(pageUtil)); } /** * @param categoryName * @param categoryIcon * @return com.hbu.myblog.util.Result */ @RequestMapping(value = "/categories/save", method = RequestMethod.POST) @ResponseBody public Result save(@RequestParam("categoryName") String categoryName, @RequestParam("categoryIcon") String categoryIcon) { if (StringUtils.isEmpty(categoryName)) { return ResultGenerator.genFailResult("请输入分类名称！"); } if (StringUtils.isEmpty(categoryIcon)) { return ResultGenerator.genFailResult("请选择分类图标！"); } if (categoryService.saveCategory(categoryName, categoryIcon)) { return ResultGenerator.genSuccessResult(); } else { return ResultGenerator.genFailResult("分类名称重复"); } } /** * @param categoryId * @param categoryName * @param categoryIcon * @return com.hbu.myblog.util.Result */ @RequestMapping(value = "/categories/update", method = RequestMethod.POST) @ResponseBody public Result update(@RequestParam("categoryId") Integer categoryId, @RequestParam("categoryName") String categoryName, @RequestParam("categoryIcon") String categoryIcon) { if (StringUtils.isEmpty(categoryName)) { return ResultGenerator.genFailResult("请输入分类名称！"); } if (StringUtils.isEmpty(categoryIcon)) { return ResultGenerator.genFailResult("请选择分类图标！"); } if (categoryService.updateCategory(categoryId, categoryName, categoryIcon)) { return ResultGenerator.genSuccessResult(); } else { return ResultGenerator.genFailResult("分类名称重复"); } } /** * @param ids * @return com.hbu.myblog.util.Result */ @RequestMapping(value = "/categories/delete", method = RequestMethod.POST) @ResponseBody public Result delete(@RequestBody Integer[] ids) { if (ids.length < 1) { return ResultGenerator.genFailResult("参数异常！"); } if (categoryService.deleteBatch(ids)) { return ResultGenerator.genSuccessResult(); } else { return ResultGenerator.genFailResult("删除失败"); } } }
处理管理员界面请求:
