我正在尝试删除白标签错误页面，所以我所做的是为“ / error”创建了一个控制器映射，
<pre><code>@RestController
public class IndexController {

@RequestMapping(value = "/error")
    public String error() {
        return "Error handling";
    }

}
</code></pre>但是现在我得到了这个错误。
<pre><code>Exception in thread "AWT-EventQueue-0" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerMapping' defined in class path resource [org/springframework/web/servlet/config/annotation/DelegatingWebMvcConfiguration.class]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping found. Cannot map 'basicErrorController' bean method 
public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletR equest)
to {[/error],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}: There is already 'indexController' bean method
</code></pre>不知道我做错了什么。请指教。编辑：已经添加 error.whitelabel.enabled=false 到application.properties文件中，仍然出现相同的错误
