71.10 Use Thymeleaf 3

By default, spring-boot-starter-thymeleaf uses Thymeleaf 2.1. You can use Thymeleaf 3 by overriding the thymeleaf.version and thymeleaf-layout-dialect.version properties, for example:

<properties>
    <thymeleaf.version>3.0.0.RELEASE</thymeleaf.version>
    <thymeleaf-layout-dialect.version>2.0.0</thymeleaf-layout-dialect.version>
</dependency>

To avoid a warning message about the HTML 5 template mode being deprecated and the HTML template mode being used instead, you may also want to explicitly configure spring.thymeleaf.mode to be HTML, for example:

spring.thymeleaf.mode: HTML

Please refer to the Thymeleaf 3 sample to see this in action.

If you are using any of the other auto-configured Thymeleaf Extras (Spring Security, Data Attribute, or Java 8 Time) you should also override each of their versions to one that is compatible with Thymeleaf 3.0.
