我有两种映射模式 /userdetails 一种用于获取请求，一种用于发布请求。

在我将 Spring 授权集成到我的项目中之前，它工作正常。现在我遇到错误了，知道为什么会这样吗？

我的两个映射是这样的。

@RequestMapping(value = "/userdetails* ", method = RequestMethod.GET) 

@RequestMapping(value = "/userdetails*", method = RequestMethod.POST)

请提出此错误的任何原因。

Caused by: java.lang.IllegalStateException: Cannot map handler 'LoginController' to URL path [/userdetails]: There is already handler of type [class com.sample.user.controller.MyController] mapped.

我遇到了类似的问题。我已经用“@Controller”定义了控制器类，并且在 Spring-config.xml 文件中定义了一个 bean 并注入了依赖项。

这是造成问题的原因。@Controller 正在定义 bean，xml 文件中定义的 bean 正在重新定义依赖项。我尝试自动装配依赖项并将其作为 bean 从 xml 文件中删除。然后它起作用了。
