Spring Boot 生產環境模板引入錯誤

生產環境引入模板報錯

使用SpringBoot 推薦的模板引擎Thymeleaf時，在Eclipse中運行正常，但打成Jar包運行時，報錯：
template might not exist or might not be accessible by any of the configured Template Resolvers

解決方案

修改application.properties 文件

spring.thymeleaf.prefix=classpath:templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.cache=false

修改Controller類的返回路徑

@RequestMapping("/user/list")
public String toList() {
    return "user/userlist";
}

其中：
return “/user/userlist”; //在eclipse中運行正常，打成jar找不到模板
return “user/userlist”;//在eclipse中運行正常、Jar形式運行正常
