spring Boot的thymeleaf自动配置试图解决rest应用程序的错误模板时出现问题

Question

我的Spring Boot REST应用程序只对邮件模板使用Thymeleaf。

不幸的是，当遇到错误时，我的引导配置试图解决错误模板。

参见下面的例外情况：

server.error.whitelabel.enabled=false

Answer 1

在application.properties中使用此属性：

spring.thymeleaf.enabled=false

似乎禁用了spring mvc的thymeleaf-同时仍然保留邮件模板的thymeleaf。

请参见这里的spring boot源代码。
