“循环视图路径将分派回当前处理程序 URL。” 使用 Spring Boot 和 Thymeleaf 时

Max*_*nol 5 java spring maven thymeleaf spring-boot

使用 Spring Boot 和 Thymeleaf 时,尝试访问 /home URL 时,我收到以下信息:

ServletException:循环视图路径 [home]:将再次分派回当前处理程序 URL [/home]。检查您的 ViewResolver 设置!(提示:这可能是由于默认视图名称生成而导致未指定视图的结果。)

使用注释 @RestController 而不是 @Controller 来注释控制器类“HomeController”。
似乎与循环视图路径错误重复 Spring boot
