尝试编写授权jwt + csrf的api，但出现错误。
如何解决？
预先感谢
错误： 创建在类路径资源[org / springframework / data / rest / webmvc / config / RepositoryRestMvcConfiguration.class]中定义的名称为“ restHandlerMapping”的bean时出错：通过工厂方法实例化Bean失败；嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[org.springframework.data.rest.webmvc.support.DelegatingHandlerMapping]：工厂方法“ restHandlerMapping”引发了异常；嵌套的异常是java.lang.IllegalStateException：缺少路径映射。 Bean'repositoryController'中的处理程序方法'org.springframework.data.rest.webmvc.RepositoryController＃optionsForRepositories（）'必须映射到非空路径。如果要映射到所有路径，请显式映射到/ **或**。

答案 0 :(得分：0)
当我意外地为相同的请求方法和端点定义两个控制器方法时，这发生在我身上。
答案 1 :(得分：-1)
我确认问题是我拥有的spring boot版本。
只需将版本更改为2.2.0.M1，它就会起作用。
