Spring 安全错误循环视图路径 [索引]:将再次调度回当前处理程序 URL [/index].检查您的视图解析器设置

我在使用 gradle 运行 Spring 启动安全应用程序时遇到以下错误 -

javax.servlet.ServletException：圆形视图路径 [index]：将再次调度回当前处理程序 URL [/index]。检查您的视图旋转变压器设置！(提示：由于生成默认视图名称，这可能是未指定视图的结果。 at org.springframework.web.servlet.view.InternalResourceView.prepareForRendering(InternalResourceView.java：210( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.view.InternalResourceView.renderMergedOutputModel(InternalResourceView.java：148( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.view.AbstractView.render(AbstractView.java：316( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java：1373( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java：1118( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.DispatcherServlet.doDispatch(DispatcherServlet.java：1057( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java：943( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java：1006( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java：898( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at javax.servlet.http.HttpServlet.service(HttpServlet.java：634( [tomcat-embed-core-9.0.29.jar：9.0.29] at org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java：883( [spring-webmvc-5.2.2.RELEASE.jar：5.2.2.RELEASE] at javax.servlet.http.HttpServlet.service(HttpServlet.java：741( [tomcat-embed-core-9.0.29.jar：9.0.29]

我在应用程序中添加了以下代码 -

你忘记了一个依赖关系。请补充

implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'

到您的依赖项。
