优点
1、动静结合:Thymeleaf 在有网络和无网络的环境下皆可运行,即它可以让美工在浏览器查看页面的静态效果,也可以让程序员在服务器查看带数据的动态页面效果。
2、开箱即用:它提供标准和spring标准两种方言,可以直接套用模板实现JSTL、 OGNL表达式效果,避免每天套模板、该jstl、改标签的困扰。同时开发人员也可以扩展和创建自定义的方言。
3、多方言支持:Thymeleaf 提供spring标准方言和一个与 SpringMVC 完美集成的可选模块,可以快速的实现表单绑定、属性编辑器、国际化等功能。
4、与SpringBoot完美整合,SpringBoot提供了Thymeleaf的默认配置,并且为Thymeleaf设置了视图解析器,我们可以像以前操作jsp一样来操作Thymeleaf。
#缓存配置,默认即是true,开发阶段设置为false
spring.thymeleaf.cache = false
#设置模板使用的编码为utf-8
spring.thymeleaf.encoding = UTF-8
#指定为模板使用的模式为html5,默认html
spring.thymeleaf.mode = HTML5
#指定前缀,默认位置为/templates/,可以修改成其它位置
spring.thymeleaf.prefix = classpath:/templates/
#指定模板文件后缀,默认值为.html,可以修改成其它值
spring.thymeleaf.suffix = .html
