如何解决这个问题？。
提前感谢。

首先检查视图解析程序的配置是否正确。在代码中，我找不到正在配置的视图解析程序，这可能会导致问题。在application.properties中，您已禁用thymeleaf视图解析器，因此spring不会为您自动配置它：

spring.thymeleaf.enabled=false
如果您使用Thymeleaf，您还有一个名为thymeleafviewsolver的Thymeleaf解析器 “thymeleafViewResolver”。它通过围绕 带有前缀和后缀的视图名称。前缀是 spring.thymeleaf.prefix，后缀为spring.thymeleaf.sufix。 前缀和后缀的值默认为“classpath:/templates/” 和“.html”。您可以通过 提供相同名称的bean

还要确保在pom中添加了spring boot thymeleaf依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
    <version>1.4.0.RELEASE</version>
</dependency>
如果您使用的是jsp作为视图解析器，则可以通过
appapplication.yml
或
application.properties
使用默认配置进行配置。但是jsp只能与WAR一起正常工作，并注意添加必要的依赖项

spring.mvc.view.prefix=/WEB-INF/view/
spring.mvc.view.suffix=.jsp
如果我们没有明确注册任何ViewResolver，默认情况下将使用其“prefix”和“suffix”属性设置为空字符串的
InternalResourceViewResolver
实例。这意味着，我们必须在应用程序中使用完整视图路径。如果不这样做，由于视图路径的构造方式，将出现循环视图路径异常。

关于您的循环依赖关系，这里有一篇相关文章：
