由於之前的系統寫了大量的jsp 要將模板升級到thymeleaf會造成工作繁瑣 所以整合成了雙模板 這裡對雙模板的整合做詳細記錄 一邊以後檢視。

一、專案結構

二、application.properties

三、java配置(展示檢視解析的配置)

    	viewResolver.setCache(false);
    	
        return viewResolver;
    }


}
 

如圖所示，使用thymeleaf模板的html檔案我會放在resource/templates/thymeleaf下，jsp檔案我會放在webapp/WEB-INF/views/路徑下。

四、Controller

使用jsp模板:

	@GetMapping(produces = "text/plain;charset=utf-8")
	public String page_List(Model  model) {
		
		return "views/admin/sys/legal/legal_list";
	}

使用thymeleaf模板：

		@GetMapping(produces = "text/plain;charset=utf-8")
		public String page_List(Model  model) {
			
                    model.addAttribute("msg", "thymeleaf歡迎你");

		 return "thymeleaf/index";
		}
		
 

五、靜態頁面及展示
