我正在开发一个几乎干净的 grails 1.3.7 项目，其中安装了 weceem 1.0RC2、spring-security-core 1.1.3、spring-security-ui 0.1.2、weceem-spring-security 1.0 及其依赖项。

除用户登录外，一切正常。当我想通过 http://localhost:8080/appname/login 登录时我只收到以下错误消息:

Sorry, we were not able to find a user with that username and password.

最佳答案

我刚刚解决了一个症状相同的问题。

事实证明，我在 Config.groovy 中的映射闭包有错字，我将一个不存在的字段映射到用户 weceem View 中的“密码”字段。

所以插件注入(inject)的自定义 UserDetailsS​​ervice 只是讨厌我的用户对象，并且没有任何工作正常。

我在映射的域侧将 passwd 更改为密码，以使其与我的 User 对象中的实际内容相匹配，并且一切正常。

关于grails - 为什么我无法使用 grails 框架 1.3.7 中安装的 spring security 和 weceem 插件登录，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/6341348/
