The error message suggests that the application is unable to locate the templates in the specified classpath directory. You need to ensure that the templates are present in the correct directory and that the Thymeleaf configuration is properly set up. 1. Verify the templates directory: Check that the templates are present in the correct location (i.e., `classpath:/templates/`). Ensure the templates are in the resources directory (usually `src/main/resources/templates/` in a Maven project structure). 2. Check Thymeleaf configuration: Make sure you have correctly configured Thymeleaf in your application. Thymeleaf requires a `ViewResolver` to locate templates. Check that you have configured the `ViewResolver` correctly and that it is mapping the correct template location. 3. Verify dependencies: Ensure that you have the required dependencies for Thymeleaf in your project. Check your `pom.xml` (for Maven) or `build.gradle` (for Gradle) file to ensure that the necessary Thymeleaf dependencies are included. If the issue persists, please share your application configuration or relevant code so that I can provide more specific help. [2023-10-07 10:58:25 | AI写代码神器 | 1147点数解答]
