Question

我在使用 spring-boot-devtools 时遇到问题，当应用程序启动时，spring boot会加载控制器中定义的所有映射。

但是当在控制器中进行一些更改并使用CTRL + F9在Intellij IDEA中构建时，spring-boot-devtools会启动并重新加载类，但它不会再次加载控制器映射。

此应用程序没有/ error的显式映射，因此您将此视为后备。

我偶然发现了同样的问题。添加thymeleaf配置类为我解决了它。

类似的东西：

@Configuration
public class ThymeleafConfiguration {
    @Bean
    public ITemplateResolver defaultTemplateResolver() {
        TemplateResolver resolver = new FileTemplateResolver();
        resolver.setSuffix(".html");            
        resolver.setPrefix("/home/.../IdeaProjects/.../src/main/resources/templates/" );
        resolver.setTemplateMode("HTML5");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(false);
        return resolver;
    }
}

Spring Boot devtools控制器映射不会重新加载
