将spring.thymeleaf.mode=HTML5(此行不写或这样写则表示默认严格检查)
改成spring.thymeleaf.mode=LEGACYHTML5
注意点:LEGACYHTML5必须是在引入了一个nekohtml依赖后,才起作用,所示必须依赖这个包
<!--为了使thymeleaf对html5非严格检查,LEGACYHTML5起作用--> <dependency> <groupId>net.sourceforge.nekohtml</groupId> <artifactId>nekohtml</artifactId> <version>1.9.22</version> </dependency>
如果不引入包,会报错:
There was an unexpected error (type=Internal Server Error, status=500). Cannot perform conversion to XML from legacy HTML: The nekoHTML library is not in classpath. nekoHTML 1.9.15 or newer is required for processing templates in "LEGACYHTML5" mode [http://nekohtml.sourceforge.net]. Maven spec: "net.sourceforge.nekohtml::nekohtml::1.9.15". IMPORTANT: DO NOT use versions of nekoHTML older than 1.9.15.
