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);
