• SpringBoot如何同时整合thymeleaf html和jsp

关键点在于两个： 1、配置order属性  2、配置viewnames属性

 

Controller 层

 return new ModelAndView("jsp/index");

或者

return "jsp/index"


 对应访问 /WEB-INF/jsp/index.jsp
 ==========================
直接返回String类型字符串 
return  "index".

对应访问 /WEB-INF/templates/index.html

}

Controller层

 @GetMapping("testJsp")
    public String testJsp(Model model) {
        model.addAttribute("message", "this is index jsp page");
        return "jsp/test";
    }

    @GetMapping("testThymeleaf")
    public String testVue(Model model) {
        model.addAttribute("message", "this is index html Thymeleaf");
        return "test";
    }

 

整合完成   jsp文件放置再/WEB-INF/jsp/下  同时访问jsp文件 字符串必须以  jsp/ 为标记通知springMvc使用 jsp引擎

其余的就使用Thymeleaf 引擎

多引擎同理设置即可
