这是堆栈跟踪：

另外，我发现了另一个问题。我试图定制Spring MVC，因此我编写了一个配置类：

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Bean
    public WebMvcConfigurerAdapter webMvcConfigurerAdapter() {
        WebMvcConfigurerAdapter adapter = new WebMvcConfigurerAdapter() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                // welcome page
                registry.addViewController("/").setViewName("index");
                registry.addViewController("/index.html").setViewName("index");
            }
        };
        return adapter;
    }
}

但IDEA显示，

WebMVCConfigureAdapter

已被弃用。我该怎么办？我在Spring Boot参考文档中找不到解决方案。

要呈现视图，需要使用

@Controller

更改此项：

@RestController
public class LoginController {
}

致：

哦，我试过这个，但也没用。这很奇怪。是否提供stacktrace？使用

WebMvcConfigurer

而不是

WebMVCConfigureAdapter

。我怀疑的一件事是路径模式可能是原因。对于安全页面，您应该添加。@soorapadman我一次又一次地检查了查看路径，但没有发现问题所在。

@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Bean
    public WebMvcConfigurerAdapter webMvcConfigurerAdapter() {
        WebMvcConfigurerAdapter adapter = new WebMvcConfigurerAdapter() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                // welcome page
                registry.addViewController("/").setViewName("index");
                registry.addViewController("/index.html").setViewName("index");
            }
        };
        return adapter;
    }
}

@RestController
public class LoginController {
}

@Controller
public class LoginController {
}
