我很清楚这个问题已经被问过了,但是没有一个答案对我有帮助。stacktrace中提到的“webcontroller”不存在,它以前就存在过。我希望你能帮助我。。
**org.springframework.beans.factory.beancreationexception:创建名为“requestmappinghandlermapping”的bean(在类路径资源中定义)时出错
[org/springframework/boot/autoconfigure/web/servlet/webmvcautoconfiguration$enablewebmvcconfiguration.class]:调用init方法失败;嵌套异常为java.lang.illegalstateexception:不明确Map。无法Map“webcontroller”方法
com.example.demo.controllers.webcontroller#showform(personform)to{get[/register]}:已经有了'registercontroller'bean方法
**
Map了com.example.demo.controllers.registercontroller#showform(personform)。

这个问题就像你有两种相同的方法
Ambiguous mapping Cannot map
在registercontroller中,get和post具有相同的名称,并为这些Map方法指定了一些不同的名称。hi3rlvi22#
当您有多个具有相同名称和完全相同http predicate (get、post、put、delete)的请求Map时,会发生此异常。
在您的情况下,您必须声明
GET /register
在另一个文件中创建之前的端点Map。替换这个
GET /register
例如,具有某些前缀的端点/vehicle/register
使其与之前的Map区分开来。它会解决你的问题。
