我有使用Spring Boot和thymeleaf的以下问题，我无法解决它。 在错误发生后立即运行Application类时发生错误。
我与百里香的布局在于

将以下内容添加到您的properties应修复它。
... other properties here ... 3.0.3.RELEASE 2.2.1
我正在使用基于以下项目的相同设置：
org.springframework.boot spring-boot-starter-parent 1.5.2.RELEASE
当我开始将Spring Boot 1.5.14升级到Spring Boot 2.0.4.时，我得到了错误classnotfoundexception: org.thymeleaf.spring5.ispringtemplateengine Spring Boot 2.0.4. 谷歌搜索时，这个post是最好的结果。
我已经在使用Thymeleaf 3.0.7 。 Spring Boot升级后，它不再有效。 经过一些反复试验后，我注意到我没有将依赖性thymeleaf-spring4升级到thymeleaf-spring5 ，当我在它时，我将Thymeleaf升级到3.0.9 。 这对我来说就是诀窍。
