在pom.xml文件中添加以下配置
<properties> <thymeleaf.version>3.0.9.RELEASE</thymeleaf.version> <!-- 布局功能的支持程序 thymeleaf3主程序 对应 layout2以上版本 --> <!-- thymeleaf2 对应 layout1版本 --> <thymeleaf-layout-dialect.version>2.3.0</thymeleaf-layout-dialect.version></properties>123456如何找到这两项的配置呢？[官方文档已经告诉我们了]
找到spring-boot-dependencies这个文件，在里面找对应的配置即可
报错！！！
