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

初学SpringBoot+Thymeleaf，在写项目时遇到如下错误：

[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:1072) [thymeleaf-3.0.11.RELEASE.jar:3.0.11.RELEASE]

问题根源：

以下是我在配置文件中写存放路径（参见Spring Boot企业级开发教程 黑马程序员编著）

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

解决方法

修改为

spring.thymeleaf.prefix= classpath:/templates/
