錯誤類型：Exception processing template "xxx": Error resolving template [xxx], template might not exist or might not be accessible by any of the configured Template Resolvers

初學SpringBoot+Thymeleaf，在寫項目時遇到如下錯誤：

[THYMELEAF][http-nio-8081-exec-6]
Exception processing template "xxx": Error resolving template [xxx], template might not exist or might not be accessible by any of the configured Template Resolvers
org.thymeleaf.exceptions.TemplateInputException: Error resolving template [homepage], template might not exist or might not be accessible by any of the configured Template Resolvers
	at org.thymeleaf.engine.TemplateManager.resolveTemplate(TemplateManager.java:869) ~[thymeleaf-3.0.11.RELEASE.jar:3.0.11.RELEASE]
	at org.thymeleaf.engine.TemplateManager.parseAndProcess(TemplateManager.java:607) ~[thymeleaf-3.0.11.RELEASE.jar:3.0.11.RELEASE]
	at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1098) [thymeleaf-3.0.11.RELEASE.jar:3.0.11.RELEASE]
	at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1072) [thymeleaf-3.0.11.RELEASE.jar:3.0.11.RELEASE]

問題根源：

以下是我在配置文件中寫存放路徑（參見Spring Boot企業級開發教程 黑馬程序員編著）

spring.thymeleaf.prefix= classpath:resources/templates/

解決方法

修改為

spring.thymeleaf.prefix= classpath:/templates/
