springboot整合thymeleaf手动渲染

Thymeleaf手动渲染

为提高页面访问速度，可缓存html页面，客户端请求从缓存获取，获取不到再手动渲染

在spring4下

@Autowired ThymeleafViewResolver thymeleafViewResolver; @Autowired ApplicationContext applicationContext; public String list(HttpServletRequest request, HttpServletResponse response, Model model) { //取缓存 String html = redisService.get("goods_list", String.class); if(!StringUtils.isEmpty(html)) { return html; } //获取商品列表 List<GoodsVo> goodsList = goodsService.listGoodsVo(); model.addAttribute("goodsList", goodsList); //手动渲染 SpringWebContext ctx = new SpringWebContext(request,response, request.getServletContext(),request.getLocale(), model.asMap(), applicationContext ); html = thymeleafViewResolver.getTemplateEngine().process("goods_list", ctx); //写缓存 if(!StringUtils.isEmpty(html)) { redisService.set("goods_list", html); } return html; @Autowired private ThymeleafViewResolver thymeleafViewResolver; SpringWebContext ctx = new SpringWebContext(request, response, request.getServletContext(), request.getLocale(), model.asMap(), applicationContext); // 手动渲染 html = thymeleafViewResolver.getTemplateEngine().process("这里写html页面名称", ctx);

在spring5

@Autowired ThymeleafViewResolver thymeleafViewResolver; model.addAttribute("user", user); //查询商品列表 List<GoodsVo> goodsList = goodsService.listGoodsVo(); model.addAttribute("goodsList", goodsList); String html = redisService.get(GoodsKey.getGoodsList, "", String.class); if (!StringUtils.isEmpty(html)){ return html; } WebContext ctx = new WebContext(request,response,request.getServletContext(), request.getLocale(),model.asMap()); thymeleafViewResolver.getTemplateEngine().process("goods_list",ctx); return "goods_list";

 

@Autowired private ThymeleafViewResolver thymeleafViewResolver; WebContext ctx = new WebContext(request,response,request.getServletContext(),request.getLocale(),model.asMap()); // 手动渲染 html = thymeleafViewResolver.getTemplateEngine().process("这里写html页面名称", ctx);
