Question

我正在做一些春季启动示例。

一个就像下面一样;

@Controller
public class WebController {

    @GetMapping("/verify")
    public String showForm(PersonForm personForm) {
        return "form";
    }

    @PostMapping("/verify")
    public String checkPersonInfo(@Valid PersonForm personForm, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            return "form";
        }
        return "redirect:/results";
    }
}

和配置类：

@Configuration
public class WebMvcConfiguration extends WebMvcConfigurerAdapter {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/results").setViewName("results");
    }
}

哪种方法正常。

但是，如果我添加如下所示的RestController，则所有不存在的无效网址都会映射到下面的类（包括根“/”）。我不再获得WhiteLabel错误页面了。 results视图也映射到此类

@RestController
public class GreetingController {

    private static final String baseTemplate = "Hello, %s!";
    private final AtomicLong counter = new AtomicLong();

    @GetMapping(name = "/greeting")
    public Greeting greet(@RequestParam(value = "name", defaultValue = "World") String name) {
        return new Greeting(counter.incrementAndGet(), String.format(baseTemplate, name));
    }
}

添加WebMvcConfiguration时，为什么会忽略RestController？我在这里做错了什么？

注意：我使用的是Spring Boot Version 1.4.3.RELEASE。

一些日志：

如果添加了@RestController，则忽略SpringBoot ViewController
